The new battery isn't charging. Is it defective battery?

New batteries are shipped in a discharged condition or with very low capacity and must charged before use. We generally recommend an overnight charge (approximately twelve hours). Refer to the user's manual for charging instructions. Rechargeable batteries should be cycled (fully charged and then fully discharged) three to five times initially to allow them to reach their full capacity.(Note: it is normal for a battery to become warm to the touch during charging and discharging).

Note: New batteries are hard for the device to charge; they have never been fully charged and are therefore "unformed". Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.

How to discharge and charge laptop battery ?

A typical charge and discharge cycle is as follow:

1. Install your newly purchased battery into your laptop.
2. Disconnect the AC adapter and use your laptop until it itself shuts down. In this situation, the battery is fully discharged.
3. Connect the AC adapter and your battery should start charging.
4. Charge until the battery is full. Repeat this charge and discharge cycle a few times and your battery pack will be conditioned to perform at full capacity.
5. Note: Please do not overdischarge and overcharge your battery.
