How to prolong the lifetime of IBM THINKPAD R40 battery ?

1.Avoid frequent full discharges because this puts additional strain on the IBM THINKPAD R40 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.Keep the IBM THINKPAD R40 batteries cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
3.Consider removing the IBM THINKPAD R40 battery from a laptop when running on fixed power.
4.If you have a spare battery for IBM THINKPAD R40, 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.

How to store IBM THINKPAD R40 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 batteries:
1.Keep IBM THINKPAD R40 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 lithium-ion 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 IBM THINKPAD R40 laptop battery; avoid buying dated stock,Observe the manufacturing date, if available.
