Automatic SLA battery chargers are
designed so that they can and will not charge defective SLA batteries. This is a
safety feature. If a defective SLA battery is attempted to be charged it could
overheat and melt or damage the equipment that it is located in.
Good SLA batteries bounce back above
their rated Voltage level within a few minutes after being fully discharged. If
a SLA battery's Voltage does not bounce back to above its rated Voltage level
within a few minutes after being discharged then it is usually considered
defective or worn out.
Some riders want to
use their electric scooters for more than one battery cycle per day so they use
a battery charger with a higher Amp rating than the original battery charger.
These fast rate battery chargers are typically rated in the 3 Amp through 6 Amp
power output range and recharge most electric scooter battery packs in 2-3
hours, however they will slightly lower the longevity of the battery pack when
compared to using a standard slow rate battery charger.
To preserve the life of the
a slow rate battery charger whenever possible. If a scooter is driven for more
than one battery cycle per day then using a smaller battery charger overnight,
and a larger battery charger during the day is the best solution.
Do not use
automotive or motorcycle battery chargers to charge SLA batteries. These type of
battery chargers are designed for charging wet cell lead-acid batteries and if
used on SLA batteries may cause permanent damage to the battery and equipment
due to overcharging and overheating.
