Lenovo MB40B Laptop Battery: Overview
The Lenovo MB40B Battery is a 4000mAh, 3.8V Lithium-Ion replacement battery listed for Lenovo devices that use the BL234 battery, including the Lenovo A5000, Vibe P1M, P1MA40 and the P70 family (P70, P70t, P70-T, P70A, P70-A). It is for owners whose device battery drains too fast, will not charge, or has swollen.
This is a replacement (compatible) battery, not an original Lenovo part, and it comes with a 6-month warranty. Because Lenovo uses many similar battery codes, matching the code is the most important step before buying.
Key Features
- 4000mAh capacity – restores a full day of normal use on a device with a worn-out battery.
- 3.8V Lithium-Ion – the rated voltage of the battery it replaces.
- Part number MB40B – listed against the BL234 battery type.
- Listed device range – Lenovo A5000, Vibe P1M, P1MA40, P70, P70t, P70-T, P70A and P70-A.
- 6-month warranty – cover against early faults after fitting.
Best For
Users who want to keep an older Lenovo device in service instead of replacing it, and repair technicians who need a BL234-type battery for customer devices. A fresh battery can make an older device practical again for calls, messaging and light use.
Things to Check Before Buying
- Open your device or check the old battery label and confirm it shows BL234 or MB40B.
- Check the voltage on the old battery label; it should read 3.8V. Laptop batteries normally run at much higher voltages, so a 3.8V pack only suits devices built for it.
- Confirm your exact device model is on the list above; if it is not, ask us before buying.
- If the old battery is swollen, stop charging it and replace it straight away.
- Have a technician fit it if the battery is glued or sits under a sealed back cover.
FAQs about the Lenovo MB40B Battery

Q: Can I use it in a Lenovo laptop?
A: Only if your device's original battery is the same 3.8V MB40B / BL234 type. Most laptop batteries are 10.8V or higher, so check your old battery label first.
Q: Is this an original Lenovo battery?
A: No. It is a replacement (compatible) battery with a 6-month warranty.
