Questions about this item

How long will the 53 Wh rating actually run my Portege X30L-J?

The 53 Wh cell stores roughly the same energy as the original pack, so a full charge typically delivers several hours of mixed office work on the Dynabook Portege X30L-J.

Does the 15.4 V output match the laptop’s charging circuit exactly?

Yes, the battery is built to the OEM 15.4 V specification, so the laptop’s controller recognises it without any firmware or hardware changes.

Will the black matte casing fit the X30L-J battery bay without gaps?

The pack is moulded to the same footprint as part numbers PS0011UA1BRS and PS0010UA1BRS, so it seats flush in the Dynabook Portege X30L-J and Toshiba DURABOOK X30W-J.
