charger is malfunctioning. Allow battery/charger to
normalise and try again. If a fault remains after
trying this then contact Draper Tools.
9.2 BATTERY PACK PROTECTION
FEATURES
Overcharging protection: This feature that
ensures that the battery pack can never be
overcharged. When the battery pack reaches full
charge capacity, the transformer/charger will
automatically shut off, protecting the internal
components from being damaged.
Over-discharging protection: This feature will
stop the battery pack from discharging beyond the
recommended lowest safety voltage.
Overheating protection: The battery pack
contains an internal thermistor cut-off sensor which
shuts off the battery pack should it become too hot
during operation. This can happen if the tool is
overloaded or being used for extended periods. Up
to 30 minutes cooling time may be required,
depending on ambient temperature.
Current protection: Should the battery be
overloaded and the maximum current draw be
exceeded, the battery will shut off to protect the
internal components. The battery pack will resume
working once excessive current draw has returned
to normal, safe level.
Short circuit protection: If, for any reason, the
battery pack was to short circuit, the short circuit
protection would immediately stop the battery pack
from operating.

9.4 BATTERY LIFE EFFICIENCY AND CHARGING ADVICE
– Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after use, its internal chemical substance will
deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has
cooled for a while.
– The battery should only be used and/or charged when battery temperature is between 5°C and
30°C.
– The battery needs to be warmed-up or cooled down in order to prevent damage to the
batteries internal components,
Note: If battery is too hot or too cold, allow it to ‘normalise’ before use or charging.
Note: Failure to warm up or cool down a battery could result in serious damage to the battery,
charger and user.
