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.

Questions about this item
How long does the 4400 mAh capacity last before the 10.8 V output drops under continuous load?
The 48 Wh pack delivers 4400 mAh at 10.8 V; run-time depends on the notebook's power draw, so the voltage will sag only when the cells reach their low-voltage cutoff.
Does the built-in smart control chip generate noticeable heat or fan noise during all-day charging cycles?
The protection chip manages charging current and temperature internally; it adds no moving parts, so the battery itself stays silent and only warms slightly under heavy load.
Which original Toshiba part numbers must already be on the old battery for this MPL16230P-21 to fit?
It replaces PA3816U-1BAS, PA3816U-1BRS, PA3817U-1BAS, PA3817U-1BRS, PA3818U-1BRS and PA3819U-1BRS — match one of those codes on your original pack.
