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 machine products can be devided into handheld, stepping, riding and intelligent. And thereare 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.

Power Type Application Advantage Disadvantage
Lithium Battery Outdoor operations such as gardens, roads, courtyards, etc. Environment Friendly
easy to use
low operating cost
low noise
The purchase cost is relatively high

The using time for each time is relatively poor
AC Power Small-scale operations such as gardens and courtyards Environment friendly
Long Service Life
Poor Portacility
Fuel power Outdoor operations such as gardens and roads Strong power,
good portability
long using time per time
Poor environmental protection
high cost of use

What kind of lithium-ion lawn mower should be selected to make consumers spend less money and meet work needs at the same time?

Below we take you to understand the precautions for the selection of lawn mower lithium battery:
1. Can the battery life of lawn mower meet the time requirements?
Industrial-grade electric garden tools, keep a single battery working continuously for at least 4 hours, and the charging time cannot exceed 1. 5 hours at the same time, which is convenient for charging at noon and does not affect afternoon work.
2. Can the lawn mower meet the work intensity of the workers?
During the use of lithium-ion lawn mower, for a variety of different environments, there can be no caton and constant pruning. The best inspection method is to limit the test, cut the iron wire, and constantly increase the thickness of the iron wire to see which machinery can cut it. At the same time, the blade does not crack. This method is a better way to test the working strength, hardness, blade material, and hardness.
3. Does the Ergonomics of the Machine Conform to the Operating Habits?
The machine must conform to the operating habits of workers all the time. At present, the age of workers in the Chinese garden maintenance market is generally between 55-70 years old. Heavy garden maintenance machinery is not suitable for workers to operate. Try to choose lighter garden tools. Garden tools with knapsack batteries cannot be used because knapsack batteries are generally heavier. Workers carry them on their backs. The battery emits heat to the skin on the back of the worker when working. Long-term continuous work will cause the skin on the back of the worker to fester. At the same time, the connection between the knapsack battery and the machine requires a wire. The field environment is complex and there is a great safety risk.
4. Is the Lithium Battery Safe?
The battery is small, the heat is less, the waterproof technology, the operation settings are safer, and whether it can be operated safely in a fool-like manner are all indicators that we have to consider. These are closely related to the quality of garden tool connectors. It is necessary to choose a high-current plug for garden tools with good regular materials.
5. Is the Battery Performance for Lawm Mower Good?
A good battery decays more slowly after repeated charging. Most of the current battery cycles in China are 200 times a year. If imported batteries are used in conjunction with an excellent battery management system, the number of charge and discharge cycles of the battery can reach 800-1000 times, and the battery can be used for several years. At the same time, choosing a high—quality charge and discharge plug can make the battery perform more efficiently and safer.

Advantages Of Lithium Lawn Mower Batteries

*Besides longevity, lithium lawn mower batteries have several other advantages over lead-acid batteries.
*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.
*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.
*They are non-toxic and you can store them indoors.
*They need no maintenance compared to lead-acid batteries.
*Lithium batteries are more resilient against extreme hot and cold temperatures.
*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.
*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.
