Tips for Lenovo ThinkPad T420si Battery:

1. Your new Lenovo ThinkPad T420si 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 Lenovo ThinkPad T420si 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 Lenovo ThinkPad T420si 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 Lenovo ThinkPad T420si Battery to become warm during charging and discharging.
5. A charged Lenovo ThinkPad T420si Battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.
