How to store TOSHIBA Qosmio F20 batteries?

Batteries are perishable products that start deteriorating right from the moment they leave the factory. There are simple preventive measures that battery users can apply to slow the aging process. We provides guidelines to reduce age-related capacity losses and how to prime new and stored Qosmio F20 batteries:
1.Keep TOSHIBA Qosmio F20 batteries in a cool and dry storage area. Refrigeration is recommended but freezers should be avoided. When refrigerated, the battery should be placed in a plastic bag to protect against condensation.
2.Do not fully charge lithium and nickel-based batteries before storage. Keep them partially charged and apply a full charge before use. Store lithium-ion batteries at about 40% state-of-charge (3.75-3.80V/cell open terminal).
3.Do not store TOSHIBA Qosmio F20 fully depleted. If empty, charge for about 30 minutes before storage. Self-discharge on a depleted battery may cause the protection circuit to trip, preventing a recharge.
4.Do not stockpile TOSHIBA Qosmio F20 batteries; avoid buying dated stock,Observe the manufacturing date, if available.

What every battery user should know?

1.Can I damage my TOSHIBA Qosmio F20 battery if incorrectly prepared?
No; Li-ion is forgiving to partial and full charge. No priming is needed when new.
2.Should I use up all TOSHIBA Qosmio F20 battery energy before charging?
No, it is better to recharge more often; avoid frequent full discharges. To maintain the optimum performance of Qosmio F20 battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
3.Should I charge my TOSHIBA Qosmio F20 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.)
4.Should I remove the AC adapter when my TOSHIBA Qosmio F20 laptop is not in use?
It does not matter. The charger automatically cuts the charge current when the battery is full. TOSHIBA Qosmio F20 laptop may be connected to the AC when not in use.
5.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.
6.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.
