Basic Battery Knowledge

New batteries come in an uncharged condition. To break in a new battery, 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. Some phones have a desktop charger/conditioner which will speed up the process.
Never charge your 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, the battery may be destroyed by overcharging.
To increase the life of your 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, computer, etc. is not in use.
Store batteries in a cool, dry place away from heat and metal objects. Batteries left idle for extended periods of time will self-discharge. Just remember to charge them before use.
If your battery used to last 8 hours and now only lasts 2 hours, it could be memory effort or just time for a new battery.
