We advise to carry out some general rules and Your battery pack will work longer.

We recommend:

• to charge only original and certificated chargers;
• to store the battery pack in a room temperature;
• to warn against short circuit.

Not recommended:

• to use the battery pack in high >45°C and low <0°C temperatures;
• to charge the battery pack on a frost;
• to place in fire and in water;
• to assort;
• to discharge, using improvised means;
• to store discharged battery pack.

And it is necessary to mean, that some rules are various for Ni-MH and Li-ion battery packs:

Ni-MH battery packs:

• the operating mode with a full charge and full discharge is preferable;
• to charge better a small current, 20-30 % from capacity, within 8-10 hours;
• periodically to do training the battery pack: to make some cycles full charge - full discharge. Is better to use for this purpose the special equipment.

Li-ion battery packs:

• the deep discharge of the battery pack accelerates its ageing, therefore it is better for charging to a bowl, not supposing the full discharge;
• for a charge it is better to use high currents, from 50 % up to 100 % of capacity within 3 hours;
• never to train the battery pack - it quickly grows old.

What to do if the battery pack:

• at charging or conversation heats up more 60°C (such temperature burns a hand) - it is necessary to stop at once use of such battery pack, to test or replace;
• it was inflated - it is necessary to stop at once use and to replace;
• it is quickly charged or is quickly discharged - Ni-MH battery pack can be restored, and Li-ion it is necessary to replace the battery pack;
• the information on the display is not correct, not charged, switched off during a set or conversation or there are other not clear and inconvenient phenomena - it is necessary to test phone, the battery pack and charging device.
