Factors to Consider When Buying Lawn Mower Battery

Battery building material

The AGM and SLA technology offer a durable exterior that makes the battery in your lawn mower reliable and robust. It restricts any acid spillage. The best battery can withstand vibration and shock, and this will reduce the battery self-discharge. The calcium found in the plates helps to prevent corrosion. Therefore, when buying a lawn mower battery, you need to consider battery building material.

Cold Cranking Amps (CCA)

The cold-cranking amps indicate how much energy a battery can generate in cold temperatures. This test focuses primarily on determining battery reliability during a cold start in the morning. When looking for a lawn mower battery, make sure you check the manufacturer's specification on cold-cranking amps. Obtaining a low CCA battery can be a significant disappointment, as the product cannot start the lawn mower in certain climatic conditions. Likewise, a battery with a very high CCA can work well but will cost more without the added benefits.

Battery compartment compatibility

Many people forget to consider this factor, which is a big mistake. It is essential to check if the lawn mower battery you purchased fits or not in the model. Many lawnmower owners often have an overheated battery compartment. Typically, this happens when a small battery fits into a large case. Also, it can be due to restricted air circulation in a case. There must be space in a compartment for air to circulate correctly. Rusting and corrosion are the results of battery compartment problems. These problems can also lead to spillage. So, consider the battery compartment compatibility when buying one

Terminal size

The lawn mower batteries are available in different sizes. They are divided into various groups based on voltage and size. Typically, general batteries are included in the U1 group with 8.3" long x 5.1 "wide x 7.25 "high. Depending on the position of the positive terminal, they are divided into two types: U1R and U1. U1R batteries come with the positive terminal to the right and the 1U on the left. Although it can seem simple, the length of the battery cables has a significant impact on the connection. Before deciding on U1 or UR1, check the location of the battery positive terminal.

Mounting position

It should be ideal for mounting the battery of the lawn mower in any direction. The position for mounting the battery varies from one model to another. It should be positioned in a way that it will withstand rough roads and other similar conditions. To avoid spillage when mounting, you must purchase a fully sealed battery.

Battery life

The worst mistake you can make when buying the lawn mower battery is to get the old one. With a durable product, you can find yourself getting back to a store sooner than you think of a replacement. Note that the longer the battery remains after the manufacturing date, the less power will be produced. Buy the model, which is six months old or less. You can specify the age with the serial number.


The battery capacity of the lawn mower should be listed in the product information. Capacity is the ability of a battery to hold a charge. Also, it must be compatible with a mower requirement. Battery manufacturers measure capacity in ampere-hours or Ah. The battery with a higher capacity will cost more but provide better overall performance than the lower capacity battery.


Due to the strength, the lawn mower battery must be durable inside and out. The higher-end version inside includes the pressed glass, which absorbs vibrations. Avoid cracks that can cause spills and leaks. The external structure helps to prevent collision damage.


The battery must be inserted into the mower. Some models are easier to install than others. The best way to evaluate this is to verify whether it comes with the required hardware to install. If a battery has everything you need to use, you may be sure that all parts are well-matched with themselves.


Voltage determines the current flow within a certain period. Many batteries in lawn mowers have 12 volts. Older models can use different voltage. They are those built using the higher voltage, like 36 and 40 volts. A 12-volt charger may not be fit for devices that operate at different voltages. Some batteries are labeled lawnmower batteries, but they have a high voltage of 36-40V.

Although they have different purposes, they have been specially developed to power lawn mowers. While charging, first connect the suitable cable, then the left one. Most of the lawn batteries are serving various purposes.


Modern products can require little or no maintenance. However, you may need to continue checking the battery whether it has sat in the right place for a long time, especially in winter. So, when buying the lawn mower battery, you should consider this factor to prolong the battery's life.

Recharge speed

You need to charge the lawn mower battery, whether it is empty or you have tested the battery on the way. This means you don't have to spend a lot of time. Some models only take a few hours to recharge. This reduces maintenance costs and ensures you use the battery whenever you need it.

Reserve capacity

Always choose a battery that guarantees a high reserve capacity. This determines its ability to continue operating independently. Over time, a reserve capacity may decrease, so buying a product, which is six months old or less from the manufacturing date.

Regular charge cycle

The current batteries contain lead-acid, so organizing a regular charge cycle can extend the battery life. It makes crystallization difficult but does not affect the battery life. Also, the maintenance charger is a helpful device. This will help to keep the batteries new.
