Do not leave a fully charged battery connected to acharger since overcharging may
shorten battery lifetime.If leftunused, a fully charged battery will lose power with time
past.Leaving the device in hot or cold places, such as in closed car insummer or winter
conditions, will reduce the capacity andlifetime of the battery. Should always try to keep
the battery between 15 ℃ and 25 ℃ . Battery performance is particularly limited in
temperatures well below freezing.Do not dispose of batteries in a fire as they may
explode.Battery may also explode if damaged.
