How to Replace a Lawn Mower Battery

The Best Way to Choose a Lawnmower Battery

In the mowing seasons, a lawn mower is an essential tool for the maintenance of your lawn. Do you need to replace its battery? As there are various kinds of land mowers available. Such as electric lawn mowers, gas mowers, self-propelled mowers. For it to work in the best conditions, you need the right battery for the type of lawn mower you have. To choose the right one, you must be based on several important criteria, including the type of your mower.

Battery for Riding Mower

We often tend to neglect the lawn mower battery, yet it plays a fundamental role in its operation, especially when starting. When signs alerting the lack of battery power appear, it is essential to think about replacing it. You might find various brands of riding mower batteries to suit your needs. High-end, high-performance batteries at affordable prices are at your disposal. Consider the voltage, battery run times, amperage, and type of battery in question. If you buy online, be aware that the weight of the battery in your riding mower can influence the price.

Battery for Cordless Mowers

To boost the potential of your cordless mower, it needs a powerful and suitable battery. The battery must be powerful with sufficient autonomy for unconstrained use. To preserve your cordless mower, opt for manufacturer batteries because they are more resistant and adapt perfectly to your device. Adaptable batteries can be more affordable but less durable. The choice of battery is decisive for the longevity of your mower so do not neglect this step.

Battery for Robotic Lawnmower

To free yourself from this chore which can take time, you have equipped yourself with a robot lawnmower? You can say, A robotic mower is a lifesaver! You will therefore not be there to manage its operation, which is why having a powerful battery with an autonomy of several hours is necessary for the mowing of your lawn to be completed. Robotic mowers need a powerful battery.

To make the right choice for robotic lawnmowers, pay attention to battery life and power. You might even get a spare battery for convenient use.

What is a Lawn Mower Battery?

The lawn mower battery is a device used to start your electric mower. It is often found under the hood next to the engine. Its performance depends on its quality. The more powerful and suitable it is for your lawn mower, the better it will start it. The lawn mower battery usually does an excellent start. You can therefore effectively mow your garden.

How do I know when to replace my mower battery?

Before being unusable, a used battery shows various signs of weakness. Before the failure, the battery seems to lack power. This should alarm you, especially when the mower stops chronically. The reasons for the failure can be varied: lack of maintenance, wear, incident … A battery of poor quality or unsuitable for your mower can also prove to be less effective in the long term. Better to invest in a new battery, matching your lawn mower. This will prevent you from having to change the battery frequently, which can be more expensive than having a suitable battery first.

Which Battery for My Lawn Mower?

Do you need to change the battery in your lawn mower/ cordless lawn mower? For this, you must know its technical characteristics as well as the model of your agricultural machine.

If the battery you want to replace has little power or runs out quickly, we can choose a battery with a higher voltage and amperage. Check the user manual to make sure it is compatible.

The battery of the lawn mower 12 V 28Ah Universal, allows a starting and a range of traction. You can mow your lawn optimally.

All new batteries have a technical sheet indicating the model or part number of compatible mowers. Remember, this is an innovative area. Thus, the type or shape of the connection may have changed if your mower is older.

Finally, although you have the choice between several batteries, we recommend that you opt for a battery with a minimum current of 12 Ah and a voltage of 12 or 24 volts. The standard battery of a mower has a voltage of 12 V, sufficient for long-term use.

Battery Capacity and Intensity

The capacity and the intensity are expressed in Amperes (Ah) in Volt (V). They directly influence the power and the battery life.

The intensity of a battery indicates a higher or lower voltage. Thus, a 54 V battery will be much more powerful than an 18 V or 36 V battery. Note, however, that the battery of a riding mower does not require too much voltage. Indeed, cutting the lawn is a little difficult work and not very consuming, much less than a machine used to cut trunks or branches, for example.

The amperage will allow us to use the battery for a longer or shorter time. It is also linked to the power required to perform any type of gardening work. Those who need more power will use a lower amperage battery earlier.

Considering all this, we can say that the duration of a battery depends on:

  • The voltage (measured in volts) that the mower consumes.
  • The current capacity required by the tool (measured in Amps).
  • The type of task to be performed.

The Different Types of Batteries

In recent years, the different types of batteries have evolved considerably. We can distinguish :

  • lead-acid batteries can be opened with electrolytes of sulfuric acid diluted with distilled water or closed with a gel electrolyte. The second is easier to maintain and handle and is much more stable. But they are obviously more expensive.
  • NiMH nickel batteries appeared after NiCd with high energy density. However, they are of low capacity.
  • Lithium batteries of which there are three types including lithium-metal, lithium-polymer and lithium-ion. The latter is the most stable with the highest energy density on the market. They are especially suitable for robot mowers for optimal autonomy. Among them, Lithium-ion batteries are the most popular. Some studies said that lithium-ion batteries last longer than others.

To conclude, the choice of battery for your lawn mower is therefore essential to guarantee its longevity and performance.

Purchase Criteria for Lawn Mower Battery

Purchasing a lawn mower is not an easy decision, especially when you have to factor in things like the type of blades it has! If it has a single blade or spinning blades, and whether or not they are durable.  But before we get into that, let’s talk about what makes batteries so darn important! With all those big machines out there today with computers telling them how fast and hard to work–which can consume up as much power as some small towns–batteries ensure everything runs smoothly by giving the machine enough juice. That means if your blade isn’t sharp enough because it needs more fuel (aka gas) then one way of getting around this problem would be finding better quality batteries:

The right size and the right type

When purchasing a battery for your riding lawn mower or lawn mower, it is important to make sure that the battery is suitable for your equipment. This applies to the physical size of the battery as well as its specifications. Consult your mower’s owner’s manual to find out which batteries are recommended by the manufacturer. The size indicates whether the dimensions of a battery are suitable for installation in your mower.

In general, lawn mowers require 12 V batteries. However, car batteries are not suitable. The capacity here should be 30 Ah maximum. Often motorcycle batteries are also offered as lawn mower batteries. As long as they match the specifications of your equipment they can be used, if you have a motor wheelbarrow you can also check if the battery is compatible. Recreational batteries for jet skis, small boats, and the like may also be suitable.

However, there are also batteries specifically designed for lawn mowers and riding mowers. They are characterized by high starting power, are protected against vibrations, and do not leak. If possible, you should give preference to these batteries.

Cold start current

The cold start current or the cold test current is decisive for good starting ability. This is the current that a battery can deliver at a temperature of -17.8 ° C for 30 seconds until its voltage finally drops to an unusable level. The higher the cold test current of a battery, the easier your mower will start. The cold test current is given in A.

The capacity

The capacity of the batteries suitable for lawn mowers and ride-on mowers is approximately between 9 Ah and 30 Ah. Larger capacity batteries usually require too much space to fit into a lawn mower. In general, the required capacity depends on the engine power, the type of fuel, and the electric consumption of the vehicle. Check your mower’s owner’s manual to find out what the manufacturer’s recommended capacity is.


In the meantime, you have the choice between different technologies. In addition to the classic lead-acid battery, there are lead-acid batteries (AGM) and lead-gel batteries. All types have their advantages and disadvantages. Choose a type of battery that matches your needs.

The Advantages and Disadvantages of Lawn Mower Batteries

Batteries that are suitable for riding mowers but also for lawn mowers have advantages and disadvantages. We will analyze this in detail.


Buying a lawn mower battery can be tough work. There are so many options and it’s hard to know what will suit your needs the best. Fortunately, there is one type that always stands out as being perfect for everyone: power wheels batteries! They come in all shapes and sizes from 12-volt up to 36-volt models with varying amp-hours rated at 10 or 20 amps per hour depending on how long you want them last before needing recharged again—it really just depends on your yard size. The benefits of Power Wheels Batteries include high-quality materials designed by professionals which provide peace of mind against overheating safety performance standards while also giving superior starting power over any other model available today!

Easy to start

With an electric start system, starting your mower is a snap. Just like with a car, all you have to do is put the key in the ignition and turn it. The starter battery starts the engine.

Mow lawns in summer, remove snow in winter

With the right battery, your lawn mower can be used in all weather conditions. A high-quality battery ensures the engine starts in both arctic cold and summer heat. This is especially useful for equipment that can be used for snow removal during the winter.

Many lawn mowers can be fitted with a snow blade and thus can be used for snow removal. Snow blade is kinda different from spinning/ single blade. The right battery can be used all year round without a problem.

Modern batteries are durable

Over time, a wide variety of technologies have been developed for batteries. This gives you the flexibility to choose the right product for your lawn mower. Now there are maintenance-free batteries that you don’t need to recharge. You can buy batteries for the warm season as well as variants that are also suitable for winter. With the right choice, you can enjoy your battery for a long time.

The inconvenience

As a professional, I know that many people are interested in the disadvantages of Lawn Mower batteries. This article will list some current concerns about them to help those who want more information on this topic feel better informed and well-rounded when discussing it with others.

Service, maintenance, and testing required

The insufficient charge can shorten the battery life. It is therefore important to check the charge level and recharge the battery in time. A state-of-charge indicator can help you detect low charges in time.

Even though the battery is absolutely maintenance-free, there is still a certain amount of work to be done. Depending on the type of battery, the electrolyte should be checked and topped up with distilled water if necessary.

Deep discharge damages the battery

A faulty charger, a short circuit, long periods of inactivity, a faulty alternator and a host of other causes can lead to the almost total depletion of battery capacity. Lead-acid starter batteries are very sensitive in this regard. The constant deep discharge exerts excessive stress on the active mass of the positive plates. This can cause irreversible damage.

What is the Role of the Battery in the Lawn Mower?

As with a car, the starter battery of a lawn mower or ride-on mower provides the energy needed to start the engine. If the mower has an emergency light, this is powered by the battery when the engine is not running. When the engine is running, the alternator takes over the power supply and recharges the battery.

On most lawn mowers, the engine is equipped with an alternator which is responsible for charging the battery. Over time, the battery will weaken and should be replaced. However, there are times when the alternator is to blame when there are starting problems.

How to choose the best Mower Battery?

A better battery for a lawn mower must meet certain criteria. Because lawn tractor batteries are the most important thing to maintain your tractor. Indeed, to make a good choice, it is necessary to know the intensity and the voltage required for your battery. But whatever the engine model, consider buying a mower mower battery with a voltage of 12V. If you can’t find one, a 6V battery will be perfect. But in this case, the two 6V devices will have to be combined and connected in series. The intensity will depend on your needs and the time of use of the mower. The size is still an important parameter to take into account.

How to assemble and disassemble a lawn mower battery?

Once the choice is made, you must now remove the old battery to place the new one. This maneuver does not necessarily require the use of a technician. With a little care and prevention, you will be able to assemble your mower mower battery. Before anything else, you should get rid of any object that can conduct current to avoid the risk of electric shock.

Next, shut down the circuit and attempt to remove the battery terminals, negative terminal first. Remove the battery from its tray, taking care to put it out of harm’s way to children. Finally, put the new one in its place, then connect the terminals, this time, the positive terminal first.

Battery Maintenance for Lawn Mower

If you want to optimize the durability of your mower battery, you will need to maintain it rigorously. During periods of low temperatures, equipment must be sheltered. The ideal would be to disconnect the mower mower battery each time you finish mowing. Recharge it from time to time so that it can keep the same level of performance. When the mower is inactive, it is best to take the opportunity to charge the battery. Get a powerful charger to charge it regularly.


Is the battery of my Lawn Mower dead?

If you have a battery model lawn mower, connect the battery to a charger. And If it does not fully charge within eight hours, its lifespan is over and it should be replaced. If the battery charges fully but quickly lose its charge when not in use, it should also be replaced. When in doubt, a multimeter can help you determine if the battery is really losing power.

How to test the alternator of my riding mower?

Does your battery keep its charge while testing with the multimeter, but you still have starting problems? Then the alternator is probably broken. If your mower has headlights, turn them on with the engine running, then turn off the engine. If the lights dim, the alternator is working.

How to Check the Charge level of Lawn Mower Battery?

Battery mowers need to check the charge level regularly. Regular and sufficient charging contributes significantly to long service life. Avoid battery voltage drop and especially deep discharge by recharging the battery in time. Regular testing will help you detect a weak battery before a deep discharge occurs. Batteries with a charge level indicator are particularly useful in this case. If your battery does not have this asset, you can determine the state of charge using a multimeter.

How do I Know if my Current Battery is Bad?

If your batteries are not holding a charge or are discharging quicker than they used to then it’s time to replace them. When this happens you should consider replacing your old batteries with new ones.

Can I Clean my Riding Lawn mower battery?

In battery-powered models, lawn tractor batteries should clean if needed. If dirt and moisture get onto the battery terminals, it can promote leakage currents. Therefore, carefully clean the terminals and connections when installing the battery. In this way, you prevent corrosion of the contacts and improve load absorption as well as cold-starting ability. You can also lubricate the terminals with terminal grease.

Things to Know about Using a Lawn Mower & Lawn Mowers Battery

  • You have to be very careful about your lawn tractor batteries. There is a risk of it being completely unloaded by staying connected to the tractor or even freezing. For this reason, it is recommended to disconnect the battery, to prevent any element from draining current from ending up draining it. This is how lawn tractor batteries last long.
  • We are sad to say that we speak from experience about the dangers of corded lawn mowers. There’s nothing like accidentally bending the power cord and hearing it cut abruptly to ruin a sunny day in the garden.
  • Fortunately, you can avoid that risk entirely by choosing a cordless lawn mower, going wireless in the same way that we have done in many other walks of life. A cordless lawn mower is a lifesaver. But if you have a low budget, you should go for corded mowers. Because cordless lawn mowers’ price is higher than corded mowers. & if you have a small area to maintain, you can go for Gas mowers also. But cordless models are highly recommended if you can afford them..
  • The electric lawn mower’s power can be decreased when the battery becomes weak or begins to run out. So, don’t forget to recharge it regularly.
  • The robotic lawn mowers work well to handle thick, tall grass. Some studies said that Battery-powered mowers/Cordless Lawn Mower/ are best for tall grass or overgrown grass.
