battery is how u take care of it
do u still leave it in the laptop when u using adapter?
do u fully drain the batt power before recharging?
1. Try not to leave the battery in the laptop when using
external power especially during prolong usage (unless u expecting
power outage). Lithium batteries tends to dies faster when over fed
( yes even with protective circuitry in place). Once the battery is
fully charge you should always stop charging immediately.
2. Allow 1 to 2 hours of cool off time after you have finished
charging the battery before using it again.
3. Lithium batteries do not require deep discharge before
charging since it does not suffer from memory effect (like NiCd).
In fact lithium battery best not to over discharge and avoid
keeping in discharge state. For long term storage of
lithium, it is best charge to 70 to 90 % capacity.
4. For first charge, charge for 7-8 hours (your phone or laptop,
if the batt is inside, should be switch off). This is to
allow the battery to reach its full charge capacity using the least
charge cycle.
5. Avoid charging below temp of 15c or above 45c.
