If you own a PDA or mobile phone, you need batteries to go with it. Without a battery, your gadget can't function and it practically useless. How to keep your Battery PDA healthy, here the tips only for You.

New PDA and mobile phone battery should be charged and discharged fully. It need to be charged at least 12 hours before using it. we suggest charging and then discharging the battery 2 to 4 times so they can reach their full, rated capacity. You can discharge most batteries by unplugging the AC adapter and leaving them turned on until completely discharged.

After you have fully charged the new phone battery, never charge your phone battery for more than 14 hours. If you are using a Nickel-Metal Hydride (NiMh) or Lithium-Ion (Li-Ion) battery, your charging time should be less than 14 hours. Manufacturers' manuals normally state not to charge a battery for more than 24 hours, but if you leave it on the charger for more than 14 hours you risk damaging the battery by overcharging.

Nickel-Cadmium (NiCad) batteries suffer from an affliction known as the memory effect. The battery will only charge to the level of which the battery was last discharged due to an accumulation of gas bubbles on the cell plates. If a battery is discharged to 30% and then recharged, the battery will only charge to 30% of its capacity and thus shrinking the battery's 'gas tank.'

To increase the life of your phone batteries, don't leave them dormant for extended periods of time. Even if you use AC power most of the time, use the battery periodically to keep it fresh and healthy. Unplug your AC adapter when the phone or PDA is not in use.

Store PDA batteries in a cool, dry place away from heat and metal objects. PDA batteries left idle for extended periods of time will self-discharge. Just remember to charge them before use.

Turn off your phone if you are in the areas of difficult to get a signal. The phone will continue to try to find signal causing the battery spendthrift.

If your battery phone used to last 8 hours and now only lasts 2 hours, it could be memory effort or just time for a new battery. NiCad batteries last approximately 700 charge/discharge cycles, or about one and a half years on average. However, NiMh batteries will normally last for only approximately 400 charge/discharge cycles.
