Questions about this item

Will the PA3420U-1BRS-AX battery fit my Toshiba Satellite L10 and L20 models without modification?

Yes, this battery is guaranteed compatible with Toshiba Satellite L10 and L20 series notebooks and meets or exceeds the original OEM power specifications for those models.

How can I verify the 10.8V 4300 mAh battery is functioning correctly after installation?

After installing the battery, charge it fully and confirm the operating system reports a design capacity near 4300 mAh and a voltage of 10.8V; the integrated IC board protects against over-charging, over-discharge and short-circuits during normal use.

Does the package include a charger or only the lithium-ion battery itself?

The product is a replacement notebook battery only; no AC adapter or power cord is included, so you must use your existing Toshiba charger or purchase a compatible adapter separately.
