Dr. Battery MPL16230P-21 6-cell 4400 mAh 10.8 V laptop battery

Replacement battery for Toshiba Satellite series

This 6-cell lithium-ion unit replaces original batteries in Toshiba Satellite A660, A665, C645D, C650, C650D, C655, C655D, L510, L515, M500, M505, M645, P745, P750, P755, P755D, P770, P770D, P775, P775D and U405 models. It delivers 10.8 V and 4400 mAh capacity for mobile operation. The pack is supplied new and includes a one-year warranty.

Fits existing chassis without modification

The battery uses the original form factor and connects directly to the laptop's battery bay, requiring no extra cables, adapters or BIOS updates. Its integrated smart control chip manages charging, discharge and safety protections such as short-circuit, overheat and overload prevention. This frees the user from carrying an external power bank during typical work sessions.

Upgrades from lower-capacity or worn-out packs

Owners of the listed Satellite models whose original 6-cell batteries have degraded will regain full runtime with this 48 Wh replacement. It is not suitable for laptops that require a 9-cell or higher-capacity pack, nor for models outside the compatibility list. Buyers needing longer unplugged time than 4400 mAh provides should look for a higher-capacity alternative.
