Battery Ibm Laptop T40t41r50 ThinkpadRemove the battery from the device, reinsert it and repeat the charging procedure. • It is important to condition fully discharge and then fully charge the. battery every two to three weeks. Failure to do so may significantly shorten the battery s life this does not. apply to Li-Ion batteries, which do not require conditioning. To discharge, simply run the device under the battery s power until it shuts down. or until you get a low battery warning. Then recharge the battery as instructed battery ibm laptop t40t41r50 thinkpad in the user s. manual. • If the battery will not be in use for battery ibm laptop t40t41r50 thinkpad. a month or longer, it is recommended that it be removed from the device and. stored in a cool, dry, clean place. • It is normal for a battery to become warm to the touch during charging. and discharging. • A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period. • The milliamp-hour mAH rating of the Hi-Capacity battery will often be higher. than the one on the original battery. A higher mAH rating is indicative of a longer lasting higher capacity battery. and will not cause any incompatibilities. A Hi-Capacity battery will, in most cases, outperform the original by 30 to 50. • Actual battery run-time depends upon the power demands made by the equipment.

Keeping the battery in a cool place can prolong its life. The Li-ion battery should be stored battery ibm laptop t40t41r50 thinkpad at 40 percent rather. than full-charge state. An increasing number of modern batteries fall prey to the cut-off problem induced by a. deep discharge. This is especially evident on Li-ion batteries for mobile phones. If discharged below 2. 5V cell, the internal protection circuit often opens. Many chargers cannot apply a recharge and the battery appears to be dead. Chapter 5 Page 3 Lithium-based batteries have a defined age limit. Once the anticipated cycles have been delivered, no method exists to improve the battery. The main reason for failure is high internal resistance caused by oxidation. Operating the battery at elevated temperatures will momentarily reduce this condition. When the temperature normalizes, the condition of high internal resistance returns. The speed of oxidation depends on the storage temperature and the battery s charge state. Keeping the battery in a cool battery ibm laptop t40t41r50 thinkpad place can prolong its. life. The Li-ion battery should be stored at 40 percent rather than full-charge state. |
