Batteries for Electric Bikes and Scooters
How SLA Batteries Work
When you charge your battereies, you fill up the storage plates with as many electrons as possible, much like filling up your car's gas tank. Gradually, when the batteries age, or are not porperly cared for, the "tank" capacity gets smaller due to sulfation (rust). The older the batteries get, the less capacity they hold - leading to less and less range and ride time. Stored electrons help the battery fight against sulfating (rusting). Partially or totally empty batteries allow the sulfating process to damage the energy storage plates. So, SLA batteries need to be kept at a full charge when not in use. If left partially discharged for any length of time without a full charge, the battery cells will be damaged. Recharge promptly after each use and, when storing for extended time, recharge every month.
Signs that you may need to replace your batteries:
Shorter ride time than normal.
- Less power while riding than when your scooter/bike was new.
- Power cut-out (due to low voltage) much sooner than when your scooter/bike was new.
- Dead batteries fully charge too quickly.
- Unable to fully charge batteries, i.e. the charger never stops charging even after 12 hours.
