1. Your new 9-Cell Dell Latitude D820 laptop battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity.
2. When charging 9-Cell Dell Latitude D820 laptop battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.
3. It is important to condition (fully discharge and then fully charge) 9-Cell Dell Latitude D820laptop 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 your device under the battery’s power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user’s manual.
4. If 9-Cell Dell Latitude D820 laptop battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.
5. It is normal for 9-Cell Dell Latitude D820 laptop battery to become warm during charging and discharging.
