How to prolong the lifetime of COMPAQ 136175-B21 battery ?

1.Avoid frequent full discharges because this puts additional strain on the COMPAQ 136175-B21 battery.Recharging a partially charged lithium-ion does not cause harm because there is no memory. Short battery life in a PDA is mainly cause by heat rather than charge / discharge patterns.
2.Consider removing the COMPAQ 136175-B21 battery from a PDA when running on fixed power.
3.Keep the 136175-B21 batteries cool. For prolonged storage, keep the batteries at a 40% charge level.
4.If you have a spare COMPAQ battery for 136175-B21, 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.Should I remove the COMPAQ 136175-B21 battery from the charger when full?
Yes, it is best to remove the COMPAQ 136175-B21 battery pack from the charger when full. A prolonged trickle charge to a fully charged battery can be harmful.
2.Should I use up all COMPAQ 136175-B21 battery energy before charging?
No, it is better to recharge more often; avoid frequent full discharges. To maintain the optimum performance of COMPAQ 136175-B21 battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
3.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.)
4.Should the COMPAQ 136175-B21 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.
5.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.
