To maximise battery life, recharge as soon as possible after
every use.
Avoid leaving the battery charger ON and plugged
into your battery for more than 12 hours at a time. Once
the battery is fully charged, turn OFF the charger and
unplug it from the pack.
Avoid charging the battery at a temperature lower
than 0 °C (32 °F) or over 40 °C (104 °F). If possible charge
the battery at room temperature.
You may recharge the battery at any time, re-gardless
of its state-of-charge. As your battery ages, it will gradually
lose capacity. With proper care and maintenance, your
battery will retain up to 80% of its capacity over at least 500
discharge/recharge cycles. As capacity diminishes, you will
notice a gradual drop-off in maximum range capability. When
range falls to an unacceptable level, contact your Ultra Motor
dealer for a replacement battery.
Low battery charge
The motor controller and battery management system
(BMS) are designed to turn off the power to the motor
when the voltage of the battery drops to a predetermined
point. This is to protect the battery from the harmful effects
of over-discharge.
When the power turns off due to a low battery, plug
the battery into the charger supplied with your A2B to
recharge the battery within 3 days. It will take 4 - 6 hours to
fully recharge a completely discharged battery.
If you have any questions about this battery or its usage,
contact our Customer Services Department.
Never attempt to use remaining power once the
BMS has switched off the battery. You will damage
your battery.
