The battery temperature is high, making
recharging impossible.
extended period is not activated, the electric
discharge might be low when using them the first
and second time. This is a temporary phenomenon,
and normal capacity will be restored by recharging
the batteries 2 – 3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become com-
pletely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the
electric current, the battery may be damaged and
its life will become shorter.
(2) 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.
CAUTION
If the battery has been heated just after operation
(or due to sunlight, etc.), the charger's pilot lamp
