What are the common faults of battery wheelchair batteries

For electric wheelchairs, batteries are the key to the drive of electric wheelchairs. In general, high-end electric wheelchairs have a relatively high price for their batteries in the market. Therefore, in the use of electric wheelchairs, battery maintenance is very important.
There are two types of batteries for electric wheelchairs on the market, one is lead-acid batteries and the other is lithium batteries.

Lead-acid battery is a kind of battery whose electrode is mainly made of lead and its oxide, and the electrolyte is sulfuric acid solution; lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution.
In terms of service life, lithium batteries can be charged and discharged 1000 times without memory, and their service life can usually reach more than 6 years, while lead-acid batteries are about 500 times or less and have a memory effect. Usually the service life is two years.
The problem that the battery is prone to is that there is no way to charge and it is not durable after charging. First, if the battery cannot be charged, check whether the charger is normal, and then check the fuse. Small problems basically occur in these two places.
Secondly, the battery is not durable after being charged, and the battery is worn out during normal use. Everyone should know this; the battery life will gradually weaken over time. This is normal battery loss; if it occurs suddenly Endurance problems are generally caused by excessive discharge.
