45 Wh Li-polymer battery for Toshiba laptops

The TAURKENAM PA5208U-1BRS is a new 10.8 V lithium-polymer replacement battery rated at 45 Wh. It targets owners of Toshiba Chromebook and Satellite models who need a direct substitute for part numbers PA5208U-1BRS, P000619700, P000645710 or PA5208U. The pack is CE, FCC and RoHS certified and built for over 500 charge cycles.

Replaces worn or failed original packs

This battery takes the place of the factory unit when runtime has dropped or the original pack no longer holds charge. The jump is worth it when the laptop shuts down unexpectedly, run time falls below usable levels, or the system flags a battery health warning. It fits Chromebook 2 Series, CB30 and CB35 Series, Satellite E45W, L55W, P55W and Radius 14 and 15 Series machines. Buyers whose laptop uses a different form factor or voltage cannot use this pack.

45 Wh capacity for daily mobile work

At 45 Wh the pack delivers enough energy for typical office, browsing and streaming sessions on the supported 14 and 15 inch platforms. High sustained loads such as video rendering or gaming will deplete the charge faster, and the fixed 45 Wh limit means runtime cannot be extended without an external power source. The 500-cycle rating indicates gradual capacity loss over years of daily charging.

Questions about this item

Will the PA5208U-1BRS pack fit inside a Toshiba Satellite E45W-C4200 chassis?

The PA5208U-1BRS is built to the exact form factor used by the Satellite E45W-C4200, Chromebook CB35-B3340 and Radius 14 L40W-C-10V series, so it slides into the existing battery bay without modification.

What is the correct sequence for installing the PA5208U-1BRS and the step users often skip?

Power off the laptop, disconnect the AC adapter, remove the old pack, insert the new PA5208U-1BRS until the latch clicks, then reconnect AC power and let the battery charge fully before first use; the skipped step is allowing that initial full charge.

How many charge cycles can the 45 Wh lithium-ion cell deliver before replacement is needed?

The cell is rated for over 500 charge and discharge cycles, so under typical daily use it will last several years before capacity drops enough to warrant a new pack.
