Fujitsu FMVNBP233B Battery for Fujitsu FMV LIFEBOOK AH Review
Fujitsu FMVNBP233B battery for the FMV LIFEBOOK AH 15.6 inch line, with the AH45, AH43 and 2020 to 2021 AH models it fits.
FMVNBP233B is Fujitsu's own 3 cell 45Wh internal pack, listed on Fujitsu's option pages as equivalent to the battery that ships in the box. It fits the 2020 to 2021 AH models (AH-X/D3, AH77/E3, AH53/E3, AH50/E3, AH43/E3, AH42/E1 and the F3 models) and the 2022 to 2023 AH45 and AH43. It does not cover the 2022 to 2023 AH50, AH53 and AH77, which use a 51Wh pack. Fujitsu says the pack is internal and not user replaceable, so plan on opening the base or using Fujitsu repair.
Fitment answer
OEM confirmed. FMVNBP233B is Fujitsu's 3 cell 45Wh internal pack, listed on Fujitsu's option pages as equivalent to the battery shipped with the laptop.
The 10.8V and 4170mAh figures come from seller listings, not Fujitsu. Fujitsu publishes 3 cells and 45Wh only.
Which laptops this fits
2020 to 2021 (Fujitsu option pages): AH-X/D3 (FMVAXD3B), AH77/E3, AH53/E3, AH50/E3, AH43/E3, AH42/E1, AH53/F3, AH50/F3, AH43/F3 and AH42/F3.
2022 to 2023: AH45/G2 and AH45/H1 on Fujitsu's option pages, plus AH45/H2 and AH43/H2, whose spec pages show the same 45Wh battery.
The full FMVA model codes are in the specification table above.
What to check before you buy
Match the model code, not the AH number. In the 2022 to 2023 range, AH45 and AH43 take this 45Wh pack while AH50, AH51, AH53, AH54 and AH77 use a 51Wh pack (FPB0364 on our site). We have no source showing the two swap, so treat them as different parts.
Fujitsu says this battery is internal and not user replaceable. Expect to open the base, or book Fujitsu's repair service.
We found no 48Wh or 90Wh variant for these models.
Part numbers this replaces
FMVNBP233, Fujitsu's earlier code for the same 3 cell 45Wh pack. Sellers also cross reference FPB0307S and FPCBP424. If the label on your old pack shows any of these, this is the replacement.
Safety and handling
If the pack looks swollen, bulges the case or lifts the keyboard or touchpad, stop using the laptop and stop charging it. Do not puncture, bend or press on it.
New lithium packs ship at partial charge because transport rules cap how charged a battery can be in transit. A pack that arrives low is normal, not faulty.
Recycle the old pack at an electronics or battery drop-off point. Never mail a used or swollen battery back to a seller.
Age and condition
Fujitsu sells FMVNBP233B as a genuine option, but the pages we read state no manufacture date policy. Ask for the date code on the label before you pay, especially from a marketplace seller.
Lithium packs lose capacity sitting on a shelf, so a pack made years ago can arrive below its 45Wh rating before its first cycle.
If this is not yours
Read the part number printed on the battery you are replacing and the model code on your laptop's label. If neither appears on this page, this is not your part.
If your AH model is an AH50, AH51, AH53, AH54 or AH77 from 2022 to 2023, look at the Fujitsu FPB0364 page instead. For everything else, browse our full laptop parts catalog at /laptop-parts.

FAQs
Can I fit a higher capacity battery in my LIFEBOOK AH45 or AH43?
We found no larger pack for these models. Fujitsu lists only the 3 cell 45Wh FMVNBP233B. The 51Wh FPB0364 belongs to the AH50, AH53 and AH77 models, and we have no source showing it fits an AH45 or AH43.
Why does my LIFEBOOK say the battery is not genuine?
We have not found Fujitsu documentation on how LIFEBOOK firmware treats a non Fujitsu pack, so we cannot tell you what a third party battery will do. Buying the genuine FMVNBP233B avoids the question entirely.
Why did my new FMVNBP233B arrive at 30 percent?
Lithium packs have to ship partly charged under transport rules, so a low reading on arrival is expected. Fit it, charge it to full on the laptop's own adapter, and judge runtime only after a full cycle.
Can I replace this battery myself?
Fujitsu says the pack is internal and not user replaceable. It can be done with the base off, but if you are not comfortable opening the laptop, we recommend Fujitsu's repair service.
