HP HSTNN-CB73 Battery

1. Your new HSTNN-CB73 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 HSTNN-CB73 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. If HSTNN-CB73 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. 4. It is normal for HSTNN-CB73 battery to become warm during charging and discharging. 5. A charged HSTNN-CB73 battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.
