How to identify the correct battery for your Toshiba / Dynabook

Check the full model on the bottom label: examples include Satellite C660/C850/L50, Satellite Pro C50, Tecra A50/Z40/X40, Portégé Z30/X30, Qosmio X70, or newer Dynabook Satellite Pro C40/C50, Tecra A50-J, Portégé X30L.
Find the battery part number (P/N): common Toshiba codes include PA3817U-1BRS, PA5107U-1BRS, PA5109U-1BRS, PA5024U-1BRS, PA5195U-1BRS, PA5185U-1BRS, and older PABAS series (e.g. PABAS263). Newer Dynabook P/Ns may appear as G71C000xxx. Matching the exact P/N is the most reliable way to ensure fit.
Removable vs built-in: some Satellite/Satellite Pro models use clip-in batteries; ultrabooks (Portégé/Tecra Z-series) are typically internal. Check the service cover or user manual.
Match voltage & capacity: verify the voltage family (e.g. 10.8/11.1 V or 14.4/14.8 V; newer packs may list 11.4/15.2 V) and the capacity (Wh) printed on your old battery.
Windows quick check (no opening required): Win+R → msinfo32 for the exact model; or run powercfg /batteryreport to capture battery details before you buy.

How to search on our website

Search by battery P/N (e.g. PA3817U-1BRS, PA5109U-1BRS, PABAS263) for an instant match.
No P/N? Enter your full laptop model (e.g. “Satellite Pro C50-H”, “Tecra A50”, “Portégé X30”, “Qosmio X70”). Adding the sub-series/year helps narrow results.
Use filters (series, capacity, voltage/cell count) to refine quickly.
Open the product page to confirm compatible models and technical specifications before purchase.

Still unsure? Leave your model name and/or battery P/N in the checkout notes and our
Compatibility Assurance team will double-check your order before we ship — so you get the right fit first time.

Battery care tips

Avoid frequent 0–100% cycles; partial charges (20–80%) help reduce wear.
Keep vents clear; heat is the main factor accelerating battery ageing.
For long storage, power down around 40–60% charge and store in a cool, dry place.
After installation, one calibration cycle can improve fuel-gauge accuracy (charge 100% → rest → discharge to ~10–15% → recharge to 100%).

FAQs

Can I upgrade to a higher-capacity pack?

Where multiple Wh options exist for the same model, you can choose a higher capacity if voltage, connector and outline match. Expect a small increase in weight/charge time.

My code is similar but not identical — is it compatible?

Toshiba P/Ns (PA****U-1BRS / PABAS***) can vary by region or production. Match by series/model, voltage, capacity, and connector layout, or contact us to confirm.

What’s the difference between Toshiba and Dynabook naming?

Recent laptops are branded Dynabook, but many parts remain cross-compatible with earlier Toshiba models. Always verify using the model and battery P/N.
