Battery care and safety
 Keep the battery in a cool, ventilated place and out of direct sunlight.

Although the battery is rechargeable, it'll eventually start to lose its ability to
recharge. If you find that the battery won't recharge, it's time to replace it.
 Please don't throw old batteries into your household rubbish. You'll find there
are special bins for batteries at refuse collection points. And some high
street electrical stores provide a battery recycling service too.
 Never throw the battery into a fire – it's highly inflammable and could
explode, hurting you or somebody else.
 When you put the battery into your phone, there's no need to use force.
Exerting too much pressure could make it leak, overheat, explode or burst
into flame.

Never take the battery apart. This may result in leakage, overheating,
explosion or fire.

If the battery becomes hot, changes colour or shape at any time (when in
use, charging or even while in storage) please stop using it immediately and
replace.
 Keep the battery dry. Damp or wet conditions can cause it to overheat or
corrode.
