How to choose correct battery?
The shape of laptop battery and the location of connection must be as same as your original battery.
Your battery part number or laptop model is listed on the compatibility list before making a purchase.
Note:
10.8v and 11.1 are compatible
14.4v and 14.8v are compatible
The 10.8v(=11.1v) and 14.4v(=14.8v) are the different voltages. They are not compatible. Please ensure you choose the right battery for your laptop.
You also can send the picture of your old battery to us and we can help you to choose it.

Warning About The Toshiba Laptop Batteries
If your capacity drops faster than you think, it means you should treat your Laptop battery or replace the original Laptop battery in time. Do not leave your Toshiba battery PA3634U dormant for long periods. We recommend using the battery at least once every two to three weeks. It's a good idea to store the Laptop part in a dry and cold place if it is not used. Clean the battery's metal contacts with rubbing alcohol on a damp cloth. Clean contacts increase energy efficiency. Turn off the wireless devices. This will save the Toshiba Satllite M300 M305 U400 U405 Pro M300 Pro U400 series battery power. Batteries degrade more quickly when they’re hot.
