There are mainly manual lawn mowers, electric lawn mowers, gasoline lawn mowers, ride-on lawn mowers, and we need to choose the most suitable batteries according to different types of lawn mowers. Lawn mower batteries are mainly lead-acid batteries, lithium-ion batteries, but the use of the battery time needs to be analysed according to different situations, in daily life on the lawn mower battery care and maintenance, in order to maximize the use of lawn mower battery time.
Different types of lawn mower batteries can be how long
1. How long can a lawn mower battery with lead-acid be used?
Mowers using lead-acid batteries have the lowest cost, generally can be used for about 3 years, but during this period you need to lead-acid batteries for regular inspection, refilling electrolyte or distilled water, avoid overcharge and overdischarge, etc., the number of times the battery is recycled can be up to about 500 times.
There are also some sealed lead-acid batteries that do not need to be refilled with electrolyte or distilled water, but the cycle life is also about 3 years. (Note: the number of cycle use refers to a complete discharge and a complete charge)
2. How long can the mower use lithium battery?
With the development of lithium battery technology, in the field of lawn care, the use of lithium batteries is becoming more and more common, mainly because of the advantages of lithium batteries, such as high energy density, high output power, long cycle life, small self-discharge rate, etc.
Gardens and lawns and so on are using different forms of lithium batteries, such as lithium-ion batteries, lithium-iron-phosphate batteries, lithium-polymer batteries, etc., and we will mainly introduce the commonly used lawn mower batteries:
2.1 Mowers use lithium-ion batteries
Lithium-ion batteries are very common in lawn mowers, mainly for manual lawn mowers, electric lawn mowers, ride-on lawn mowers, because of the high energy density of lithium-ion batteries, in the weight, efficiency and life of a good balance between the weight, efficiency and longevity, and other types of batteries compared to the same weight can be higher energy efficiency, very suitable for lawn mowers, but lithium-ion batteries for the number of times of recycling 1000 times The service life of lithium-ion battery is about 3 years.
2.2 Mowers use lithium iron phosphate batteries
Mowers using lithium iron phosphate batteries are mainly used in residential areas or places with high security requirements, mainly because lithium iron phosphate batteries are more stable and not easy to overheat, compared with lithium-ion batteries for higher security.
In general, lithium iron phosphate batteries will not be overcharged or overheating combustion or explosion phenomenon, used by people from all walks of life, and lithium iron phosphate batteries can be recycled up to 10,000 times, the service life of 10 years or so, but the price is relatively high, if you do not look at the price of lithium iron phosphate batteries is the best choice for lawn mowers.
2.3 Mowers use lithium polymer batteries
Lithium polymer batteries than lithium-ion batteries have the possibility of lower manufacturing costs, and packaging shapes, more reliable and durable, but the electric capacity is relatively small, used in lawn mowers less.
Factors affecting the duration of a lawn mower battery
1. First time charging of lawn mower battery
When charging a lawn mower for the first time, you need to make sure that the battery is charged to more than 80%, insufficient charging may lead to a reduction in the capacity of the battery, affecting the service life, so it is necessary to be fully charged, so that the battery is in the best working condition.
Of course the first charge should not be overcharged, which will also affect the service life of the battery. You can read the mower instructions to make sure the first charge is correct.
2. Avoid overcharging the lawn mower battery
Whether our lawn mower battery is lead-acid battery or lithium battery, we should avoid overcharging. Overcharging lithium batteries will cause oxidization, corrosion and other reactions, which will produce flammable gases, and the temperature inside the battery will rise and the pressure will increase, causing thermal runaway or fire.
Overcharging of lead-acid batteries will cause the active substance of lead-acid batteries to fall off, resulting in deformation of lead-acid batteries and loss of water, which will cause internal damage to the batteries in serious cases, affecting the normal use of the batteries and threatening the life and health of individuals.
3. Avoid over-discharge of lawn mower battery
Avoid over-discharge of lawn mower battery, if it is lead-acid battery over-discharge, it will make the concentration of electrolyte drop, there will be heating inside the battery, and in serious cases, the battery will undergo irreversible sulfation, resulting in the death of the battery.
If it is a lithium battery over-discharge impact relative to lead-acid batteries to be a little smaller, but it will also affect the capacity and cycle life of the battery, resulting in battery life shrinkage.
4. Reasonable storage of lawn mowers
When we do not use the lawn mower, we should reasonably store the lawn mower to avoid affecting the battery. If the ambient temperature of the storage mower is too high, the battery will become hot, and the battery’s capacity and efficiency will decrease, which may cause permanent damage, and the battery’s lifespan will be greatly reduced, resulting in the battery not being able to be used.
If the storage environment temperature is too low it will cause the internal resistance of the battery to increase, the range of the battery will be weakened, causing the capacity of the battery to decrease, causing damage to the battery.
Therefore, when we store the mower, we should pay attention to the ambient temperature around, avoid extremely high or low situation, park the mower in a dry, well-ventilated area.
5. Mower battery charger
The battery charger of the lawn mower will also affect the life of the battery, when the charger will mismatch the specification and parameters of the lawn mower battery, it will cause the charging voltage to be too high or too low, when the charging voltage is too high, it may cause the battery and the charger to be overheated, which affects the service life of the battery, and when it is serious, it will be on fire. When the charging voltage is too low, it will not be able to charge, which also affects the battery life.
6. Avoid mower battery and related wiring failure.
Avoiding mower battery and related wiring failures requires us to physically inspect the battery on a daily basis.
6.1 Check the appearance of the lawn mower battery for dents or protrusions, which may affect the integrity of the battery and affect its use.
6.2 Check the appearance of the lawnmower battery for cracks or fissures, which can lead to leakage.
6.3 Check the appearance of the lawnmower battery for foreign objects or pollution, the presence of foreign objects or pollution will affect the performance of the battery and reduce the efficiency of its use.
6.4 Check the insulation of the connection harness of the lithium-ion battery, whether there is a phenomenon of breakage, if there is a breakage will have the possibility of leakage.
6.5 Check whether the connection terminals of the mower battery harness are connected reliably to improve the performance of the battery.
6.6 Check the lawn mower battery voltage, use a multimeter to check the battery voltage, when the voltage is 0 or very low, it means that the battery is short-circuited internally or the battery is damaged, then you need to replace the battery.
How to protect the mower battery in winter
If the lawn mower battery is a removable battery, it is best to remove the battery, then fully charge the battery, purchase a battery storage box, put the battery inside the storage box, place the storage box with the battery in a dry, warm place, and charge the battery every 3 months, which I think is the best protection for the battery.
If the mower battery is non-removable, you may need to park the mower in a dry, warm place and check, charge and maintenance the battery on a regular basis in order to avoid winter damage to the battery.
What systems are available for lawn mowers
1 Electric mowers
Electric lawn mowers can be used both corded and cordless, corded electric mowers are suitable for small places and cordless electric mowers are suitable for large places, in short, electric mowers are friendly to the environment and are quieter.
2 Gasoline powered lawn mowers
They are powered by conventional gasoline, not electricity.
3 Dual purpose mowers
A combination of gasoline power and battery provided power is also a good option.
Conclusion
How long a lawn mower battery will last depend not only on the type of battery, but also on your maintenance and care of the battery, only by paying attention to the battery, we can use the battery for the longest life.
