The Best Lawn Mower Battery Buying Guide & FAQ
There are a couple of situations where you will need a new lawn mower battery. Perhaps your battery ran out of steam and can’t be brought back to charge. It could be that you got a second-hand lawn mower and want to rig it to work like new. Alternatively, you might be planning ahead (which is especially useful if you have a lot of lawn to tackle). So, what do you need to look for when buying a lawnmower? The good news is that the answer is pretty simple.
The first thing to think about is what you want out of the lawnmower. Consider how long it needs to work. Think about the area you need to cover and how frequently you are likely to need to have it in use. Once you know that, you can keep an eye on the finer details and find the features most advantageous to you.
Benefits of Lawn Mower Batteries
When you get a lawn mower battery, there are a few ways you can expect to benefit. Ever tried using a low-powered battery on your flashlight? Did you notice how much dimmer it was? Well, the same is true with lawn mower batteries. They give you the necessary amount of power and energy to get your outdoor chores done. Of course, the benefits are more far-reaching than that.
Using a battery-powered battery is often better than those with a cord (or gas-powered for that matter). The lawnmower stays lightweight and unencumbered by the restrictions of the length of your electrical cord. You can use it just about anywhere; and, when you find the right battery, it will last as long as you need it.
Lawn mower batteries offer you the necessary amount of power and the ability to recharge them. Unlike using gas, a consumable source that requires physical refills, you can simply plug the battery into a charging station. It enhances the utility of the battery, along with its overall lifespan.
- Batteries work for long periods and provide a steady, reliable supply of power to the motor.
- You don’t require a supply of gas or an electrical cord (and plug-in) to power the lawnmower.
- High-quality batteries that have well-structured interior cells are capable of lasting longer than other models.
- Battery-powered lawn mowers are more portable, especially since you can bring along a spare battery when you do off-site projects.
- Like a car battery, you can boost a lawn mower battery to bring it back to life.
- Lawn mower batteries tend to charge quickly, making lighter work of lawn maintenance.
Popular Types of Lawn Mower Batteries
Batteries are subject to voluntary standards as set forth by the United States Consumer Product Safety Commissions. As a result, most batteries for specific devices, like lawnmowers, tend to be quite similar. That said, not all batteries are made the same just as not all lawn equipment is made alike. The vast majority of batteries are standardized at 12 volts, simply because that is how most lawn mowers are made. Though the voltage is consistent, the structure and chemicals used in the batteries do differ.
Easily the most common type of lawn mower battery, 12-volt options come in all shapes and sizes. Since most lawnmowers require a power source of this voltage, this type continues to be the most prevalent on the market. Bear in mind that you can find lower voltage options if needed.
In most cases, the battery runs on a lithium-ion chemical structure. The dense chemical component holds potential energy in chemical bonds until it converts that power into electricity for the motor. There are other formulas, such as lithium-sulfur and thin film, each offering different advantages in terms of lasting power and recharge speed.
The batteries come encased in an inert material which, most of the time, consists of a polymer. The thickness and stability of this case directly impact its ability to resist damage. The battery must be capable of withstanding vibrations to ensure that it won’t leak or spill.
This is a unique kind of battery since it works as a supplement to the existing batteries on the market. Instead of fitting into the place of the battery, it acts as an external power source that feeds the battery. A key reason this type is popular is that it is compatible with any battery structure. It is similar, though not the same, as a battery charger.
In most cases, the trickle charger plugs into the wall and takes in the charge. Since the structure is so compact, you can simply keep it on hand, in case the power on your battery drops too low. The power bank feeds a steady amount of energy into the battery. This enables you to preserve your actual battery for longer.
Ideal for unique lawn mowers where getting a replacement battery isn’t as easy to do, trickle chargers enable you to keep using the mower without a retrofit. Keep in mind that, while some trickle chargers incorporate a power bank, not all of them do. It is better to stick with the options that don’t need a live power source all the time.
Though a lot of push mowers work with 12-volt batteries and thus fall into a different category, there are lawn mowers that require a higher voltage to operate. The batteries are often a bit smaller than their 12-volt counterparts yet larger than a trickle charger. This is because they are designed for smaller equipment.
When looking for a push mower battery, the first thing to look at is how much power it requires. The electrical specifications will tell you precisely what amperage/voltage you require. From there, so long as the battery is properly encased and reasonably long-lasting, it is a good option. Keep in mind that push mower batteries tend to run out of steam faster than other options since they are designed for less demanding scenarios.
What to Consider When Buying Lawn Mower Battery
When you go to pick your lawn mower battery, there are a couple of things you’ll want to keep an eye out for. The first thing you need to do is check out the land the mower will be moving over. If the land is bumpy and hilly, you will want to pick a battery that is fortified against these issues. Choose something resistant to damage, both in terms of temperature and impact. This way, you can get the longest-lasting benefits out of it.
Of course, it is more than a matter of quality. You want a lawn mower battery that fits onto your actual lawnmower. Though most are 12-volt, that doesn’t mean that the anode and cathode placement are compatible with your setup. Be sure that it is designed to fit with your lawn care machine. To take it a step further, there are a few other things to think about.
- Structure. The shape and design of the battery are about more than the electrode placement. The battery has to be able to fit onto your lawnmower. Plus, it shouldn’t be too heavy that it creates extra resistance. You want a balanced unit that fits seamlessly into your lawnmower.
- Recharge Speed. Eventually, you will need to recharge the battery, whether it died altogether or you tested the battery along the way. That said, this doesn’t have to be a hefty time investment. Some models take a mere couple of hours to charge. It cuts down on maintenance demands and ensures that you can use the battery when you need to.
- Durability. A matter of strength, the battery needs to be sturdy both on the inside and the outside. Inside, higher-end versions include a type of pressed glass that absorbs vibrations. It prevents cracks that can lead to leaks and spills. The exterior structure is there to prevent damage from impact (flying rocks, etc.).
- Installation. You are going to need to place the battery on the lawnmower. Some designs make this easier than others. A good way to assess this is to check if it comes with the necessary hardware for setup. If the battery comes with everything you need to use it, then you can be certain that all the parts are compatible with the battery itself.
Most Important Features of Lawn Mower Batteries
When you choose your lawn mower battery, there are a few key features that it must have to work. Without meeting these criteria, the battery either won’t fit or won’t perform. To find a suitable battery, an essential step is assessing each of these features. By understanding the merit of each trait, you can get a complete picture of the battery.
A critical part of the battery, this is the point of physical connection between the battery and the mower. Terminals are different on each battery in terms of strength, placement, and material. Since most of these batteries fall under the group U1 criteria, they are in the range of eight by seven by five inches in size. The terminals are most often located at the top front of the battery.
The material is another consideration. While they need to be made out of metal to ensure conductivity, the type of metal speaks directly to the lasting effects. You want a highly conductive material that isn’t prone to damage from heat. So long as they are marked properly (red for the anode and black for cathode) and made of a hardy metal, you can rely on good function.
Lastly, this feature speaks to the actual location of the terminals. You need to be able to connect them to the actual lawnmower. You can do a visual check of the battery and assess if it would fit your mower. Conversely, you can investigate the specs of the battery to be sure of compatibility.
This refers to the amount of amperage the battery can produce in half a minute when the temperature is zero degrees. Most batteries are effective in warmer conditions since heat causes the excitation of particles in the battery. The ability to work at cold temperatures means that the battery itself is a lot stronger.
While you aren’t likely to need your lawnmower in winter, the cold-cranking amps give you a complete picture of the battery’s actual abilities. It showcases the honest capacity of the chemicals and how they react with the battery’s design. In short, the higher the number of cold-cranking amps, the more effective the battery will be.
Another essential feature of any lawn mower battery is the voltage. This represents the current that can pass through the system at any point in time. In addition to the placement of the electrodes, the voltage is the other part that absolutely must be compatible. Most systems run on 12 volts, though there are always outliers. Be sure that your lawnmower matches the voltage of the system.
Ride-on lawnmowers tend to exclusively work with 12-volt batteries. That said, there are higher-voltage options out there for lawnmowers that you push. The voltage will be noted on each battery, giving you the chance to match it to the requirements of your lawnmower.
Care and Maintenance for Lawn Mower Battery
Every tool requires a certain amount of upkeep to work optimally. Lawn mower batteries are no different. The good news, however, is that caring for them is fairly simple. Most of it is a matter of storing it responsibly and protecting the battery from damage. Naturally, you want to keep it in a cool, dry location where it won’t encounter any bumps and bruises.
Before installation, you want to be sure that the battery is fully charged. While some batteries come pre-charged, this is not true of all of them. Use the screen or light indicators to determine if it needs refueling. As with any chemical-based battery, it is important to handle charging properly. Recharging (and an occasional dusting) is all the upkeep the battery needs. So long as you take care of these needs, the lawn mower battery will keep working for as long as possible.
- Store the lawnmower, the battery, and any spares indoors or under a cover.
- Be sure that your connections are firm and reliable to prevent damage.
- Clean off the electrodes before you put it into place to optimize the connection.
- Don’t overstrain the lawnmower since it can cause the battery to overheat.
- Allow the battery to drain fully before you recharge it to prevent chemical build up.
- Always charge the battery to the fullest amount possible.
