G-MAX N512 User's Manual
I did not use my spare battery for a few days. Even though it was
fully recharged, there wasn't as much power left as a newly
charged one. Why?
The batteries will self-discharge (1% per day for Li-Ion) when they are not
being recharged. To make sure a battery pack is fully charged, recharge before
use. Always keep the battery inside your notebook computer G-MAX N512 and
have the AC adapter connected whenever possible.
I did not use my spare battery for months, now I have problem
in recharging it.
If you happen to leave your battery pack to go through an extended period of
self-discharge, say more than three months, the battery voltage level will
become too low and needs to be Pre-Charged (to bring the battery voltage
level high enough) before it automatically (for Li-Ion only) resumes its normal
Fast Charge. Pre-Charge may take 30 minutes. Fast Charge usually takes 2~3
hours.
Why can't I charge my battery to 100% charged when it is
99-95% charged?
To preserve the life of the battery, the system only lets you charge the battery
when its capacity falls below 95%. However, it is recommended that you bring
an extra battery and let the battery in the system use up its power before
charging it.
