Knowing how to take care battery
| This is for Lithium-ion (Li-ion) battery only. | |
| Should I use up all battery energy before charging? |
No, it
is better to recharge more often; avoid frequent full discharges. Yes, on batteries with a fuel gauge (Smart Battery), allow a full discharge once a month to enable reset the gauge. If your battery return % back to Microsoft Windows, it is a smart battery. If your battery has indicate light on it. it is a smart battery, too. |
| Should I charge my battery partially or fully? | Does not matter. Charging in stages is acceptable. Full charge termination occurs by reading the voltage level and charge current. Charging a full battery is safe and does not cause harm. |
| Should the battery be kept charged when not in use? | Best to store at 40% charge. Cool storage is more important than state-of-charge. Do not fully deplete battery because Li-ion may turn off its protection circuit. (in other words, do not leave your battery without charging for more than one month, the voltage might go lower than the required minimum voltage.) |
| Will the battery heat up during charge? | No, little heating is generated during charge. A large laptop battery may get lukewarm. Do not allow the battery to heat during charge. |
| What are the allowable charging temperatures? | Important: Rechargeable batteries can be used under a wide temperature range. This does not automatically permit charging at these extreme conditions. The maximum allowable charge temperatures are shown below: |
| Charging Temperature Range | 5C° - 45°C (41°F - 113°F), if you charge the battery beyond this temperature, sensor may prevent charge or cut off the charge prematurely. |
