How to prolong the lifetime of IBM 02K6620 battery ?

1.Avoid frequent full discharges because this puts additional strain on the IBM 02K6620 battery.Recharging a partially charged lithium-ion does not cause harm because there is no memory. Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
2.Consider removing the IBM 02K6620 battery from a laptop when running on fixed power.
3.Keep the IBM 02K6620 laptop batteries cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
4.If you have a spare battery for IBM 02K6620, use one to the fullest and keep the other cool by placing it in the refrigerator.Do not freeze the battery. For best results, store the battery at 40% state-of-charge.


What every battery user should know?

1.How should I prepare my new battery?
Batteries comes partially charged. You can use the Lithium-ion(Li-ion) battery right away and charge it when needed, But prime new Nickel-based battery by putting on a 14-16h charge.
2.Should I remove the AC adapter when my IBM 02K6620 laptop is not in use?
It does not matter. The charger automatically cuts the charge current when the battery is full. A laptop may be connected to the AC when not in use.
3.Should I remove the IBM 02K6620 battery from the charger when full?
Yes, it is best to remove the IBM 02K6620 battery pack from the charger when full. A prolonged trickle charge to a fully charged battery can be harmful.
4.Can I damage my Li-ion battery if incorrectly prepared?
No; Li-ion is forgiving to partial and full charge. No priming is needed when new.
5.Should I use up all IBM 02K6620 battery energy before charging?
No, it is better to recharge more often; avoid frequent full discharges. To maintain the optimum performance of IBM 02K6620 battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
6.Should I charge my battery partially or fully?
Full charge termination occurs by reading the voltage level and charge current. Fully charged a Li-ion battery is safe and does not cause harm. However, regarding the Nickel-based batteries, allow full charge without interruptions. Repeated partial charge can cause heat buildup. (Many chargers terminate charge by heat. A fully charged battery will re-heat, causing overcharge.)
7.Should the IBM 02K6620 battery be kept charged when not in use?
Best to store at 40% charge or 3.75-3.80V/cell open terminal. Store in a cool, dry and clean place. Do not fully deplete battery because Li-ion may turn off its protection circuit. However,NiMH battery can be fully depleted and recharged. Priming may be needed.
8.What should I know about chargers?
Charger should apply full charge. Avoid economy chargers that advertise one-hours charge. Fastest full-charge time: 2-3 hours.
9.What are the allowable charging temperatures?
Rechargeable batteries can be used under a wide temperature range. Slow charge: 0°C - 45°C (32°F - 113°F) Fast charge: 5°C - 45°C (41°F - 113° F) Temperature sensor may prevent charge or cut off the charge prematurely. Charging a hot battery decreases the charge time. The battery may not fully charge.
