All Things You Need to Know about Lawn Mower Batteries

The garden machinery industry originated in Europe and it has a history of more than a hundred years. In 1830, the world’s first forage lawn mower powered by an internal combustion engine came out, marking the birth of garden machinery.

According to the working method, garden machinery products can be divided into handheld, stepping, riding and intelligent. And there are many kinds of lawn mowers for your selection because of their different power supply sources. In general, the power supply sources for gardening tools are devided into three parts: Fuel-based, AC-based and lithium battery based.

The Difference among Fuel-based, AC-based and Lithium battery based:
*Fuel-based engine lawn mowers are easy to use and powerful, but they have significant defects. There are two environmentally friendly elements, noise pollution and emission pollution. They are not clean in use and the storage of fuel is unsafe. Considering the increasingly serious global fuel resources and the increasingly stringent environmental protection requirements in Europe and the United States, in the long run, engine garden tools will become more and more restricted in the household field, and it is now difficult to be replaced in the professional field.

*AC garden tools are cheap, have enough power, and do not emit pollution, but they have significant defects, are inconvenient to use outdoors, and have a high risk of electric shock.

*The price of lithium battery lawn mower is relatively high and the power is weak, but the advantage is that it is convenient for outdoor use, clean and environmentally friendly. Moreover, the risk of electric shock is low. The price of power battery safety and other issues are also being gradually dealt with with the development of battery technology.

Following the further decline in battery prices, the advancement of battery specific energy and power, and the development of permanent magnet brush-less position sensor motors, lithium battery garden tools will gradually replace AC electricity and engine garden tools in the household field. Lithium battery manufacturers will also make more efforts in this regard.

Advantages Of Lithium Lawn Mower Batteries:
1. Besides longevity, lithium lawn mower batteries have several other advantages over lead-acid batteries.
2. There’s no cool-down period after charging, because lithium batteries feature a built-in battery management system (BMS). So they won’t overcharge or over-heat on the charger like lead-acid batteries.
3. Lithium batteries have a 15x lower discharge rate. They hold their charge longer than other batteries. They also charge 4 to 6 times faster than lead-acid batteries.
4. They are non-toxic and you can store them indoors.
5. They need no maintenance compared to lead-acid batteries.
6. Lithium batteries are more resilient against extreme hot and cold temperatures.
7. They feature a built-in emergency start function! Just press a button and your battery will start back up again, thanks to the battery reserve.
8. Lithium batteries are 70% lighter than lead-acid batteries.

How Long Do Lawn Mower Lithium Batteries Last?
For batteries, lead-acid battery was popular in many equipments in the past. Lithium Batteries draw people’s eyes step by step because of their great performance. Why this article illustrate that there is no position for lead-acid battery in the garden tool power supply? Lithium battery becomes main stream in electricity backup power supply becausse of low internal resistance, high voltage, large capacity and significient safety performance and etc.

Lead-acid batteries are inexpensive, but often very heavy, need a lot of maintenance. Moreover, lead-acid batteries have to be replaced far more often. Those are other resons for the phenomenon that lead-acid batteries are grandually out of date. LiFePO4 battery is one of lithium batteries which is popular in lawn mowers. LiFePO4 battery cost more upfront but weigh about 50% less than lead-acid batteries. LiFePO4 battery can last 4-6x longer, and it does not require any maintenance. You’ll likely save a lot of money for that lithium battery can run for longer time. So, now we can answer the question of how long do lawn mower batteries last. Buying replacement batteries for your lawn mower is expensive, so it’s important to have batteries that can keep going as long as your mower does.

Generally speaking, battery type, output voltage, current of a lawn mower, method of storing and maintaining lawn mower are key factors to decide how long lithium battery can last for a lawn mower.
