Plug the battery charger into the electric scooter,
bike, go kart, or vehicle before plugging it into the wall outlet.
When charging is complete unplug the charger from the wall outlet before
unplugging it from the vehicle. This will prolong the life of the battery
charger and also help to prevent sparking between the battery
charger's output plug and the charger port to prolong the life of
To get the most life out of your batteries recharge
them after every ride, even very small rides. Leaving an electric
vehicle's battery in
a partially discharged state lowers the
useful lifespan of the battery.
When a an electric scooter, bike, go kart, or
vehicle is in
storage or not being used frequently recharge the batteries every 30 days.
Some battery chargers are for standard SLA
batteries and other are for Lithium (Li-ion, LiFePO4, and LiPo) batteries. The
right type of battery charger needs to be used with the
corresponding type of battery or battery pack. Any brand of SLA battery charger may be used on any
electric scooter, bike, go kart, or vehicle that uses SLA batteries as long as the
output Voltage and Amp rating plus Connector and Connectors Terminal Polarities
are the same as the vehicles original battery charger. Battery chargers for
Lithium (Li-ion, LiFePO4, and LiPo) batteries need to have the
same output Voltage and Amp rating plus Connector and Connectors
Terminal Polarities as the vehicles original battery charger. We have a chart on our
LiFePO4, Li-ion and LiPo Battery Chargers page that can help with determining the
correct Lithium battery
charger Voltage for different batteries and battery packs.
We sell automatic "smart" battery chargers which are
designed so that they can and will not charge faulty batteries. This is a safety feature. If an
worn out, faulty, or overdischarged battery is attempted to be charged it could
overheat and damage the equipment that it is located in.
Good SLA batteries
bounce back above their rated Voltage level within a few minutes
after being discharged. If a SLA battery's Voltage does not
bounce back above its rated Voltage level within a few minutes
after being discharged then it is usually faulty
or worn out.
Sometimes riders and rental stores want to use their
electric scooters, bikes, go karts, and vehicles which have SLA
batteries for more than one battery cycle per day so
they use battery chargers with a higher Amp rating than the
original battery charger. These quick 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 slower rate
battery charger. For fast charging Lithium (Li-ion, LiFePO4, and LiPo) batteries
use only a battery charger with the same Voltage rating and a higher
Amp rating that the vehicle's manufacturer approves for use with
To preserve the life
of the SLA batteries use
a standard rate battery charger whenever possible. If a vehicle 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.
not use automotive or motorcycle battery chargers to charge SLA
or Lithium batteries. These type of battery chargers are designed for
charging wet cell lead-acid batteries and if used on SLA
or Lithium batteries may cause permanent damage to the battery and
equipment due to overcharging and overheating of the batteries.
Common Battery Charger Indicator Light Guide
||When the battery charger is plugged into the wall
and not plugged into the charger port the light will
turn green. We recommend plugging the battery
charger into the charger port first and then into the
wall to help prevent damage to the charger plug
and port from sparking.
||When the battery charger is plugged into the
charger port and plugged into the wall the red light
will glow during the first and second stages of the
charging cycle which are the bulk charging and
absorption charging stages.
||When the battery is charged between 90%-95%
the light will turn green This is the third
stage of the charging cycle which is the saturation
stage. We recommended to continue charging the
battery for 2-3 hours after the light turns green to
achieve optimal charge saturation. The maximum amount of time we
recommend charging the battery for in the saturation stage is 48 hours.
