How to maintain the lithium battery of a golf cart to extend its lifespan.

Do not replace the charger casually, and do not remove the speed limit of the controller
Chargers from various manufacturers generally have personalized needs, so do not replace them casually when unsure. If the required driving range is relatively long and multiple chargers must be equipped for long-distance charging, the charger that was recharged during the day should be replaced with a separate charger, while the original charger should be used at night. Removing the speed limit of the controller can increase the speed of some cars, but it will not only reduce the safety of the car, but also shorten the service life of the lithium battery.

Protect the charger
The general user manual contains instructions on protecting the charger. Many users do not have the habit of reading the manual, and often only think of looking for it after the problem is solved. It is often too late, so it is necessary to read the manual first. In order to reduce costs, most current chargers have not been designed with high vibration resistance. Therefore, chargers should not be placed in the trunk and basket of electric bicycles. Under special circumstances, the charger must be moved and packed with foam plastic to prevent vibration. After many chargers undergo vibration, their internal potentiometers will drift, causing the entire parameter to drift, resulting in abnormal charging status. Another thing to note is to keep the charger ventilated during charging, otherwise it may not only affect the lifespan of the charger, but also cause thermal drift and affect the charging state. This will cause damage to the battery. So, protecting the charger is also very important.

Charge every day
Even if your driving ability is not required to last long and can be used for 2 to 3 days on a single charge, it is still recommended that you charge it every day to keep the battery in a shallow cycle state, which will prolong its lifespan. Some early mobile phone users thought that it was best to charge the battery after it was basically used up. This view is incorrect, as the memory benefits of lead-acid batteries are not as strong. Frequent discharge has a significant impact on the lifespan of the battery. Most chargers may charge 97% to 99% of the battery after the indicator light changes to indicate full charge. Although only 1% to 3% of the battery is under charged, the impact on the driving ability can be almost ignored. However, it can also form under charging accumulation. Therefore, after the battery is fully charged, it is still advisable to continue floating charging as much as possible, which is also beneficial for suppressing battery vulcanization.

Charge in a timely manner
After the battery is discharged, the vulcanization process begins, and obvious vulcanization occurs within 12 hours. Timely charging can remove minor sulfurization. If not charged in time, these sulfurization crystals will accumulate and gradually form coarse crystals. General chargers are powerless against these coarse crystals, which will gradually lead to a decrease in battery capacity and shorten the battery's service life.
