Key features

Compatibility
Fits the Samsung Galaxy A91. It does not fit other A-series phones such as the Galaxy A90 or Galaxy A71, which have their own batteries. To check your model, go to Settings > About phone and look at the model number before you order.
How to fit a Galaxy A91 battery
The battery sits under the glass back panel, so you will need a heat gun or heat mat, a suction cup, opening picks and a small Phillips screwdriver. Heat and lift the back glass, remove the wireless charging and NFC cover, disconnect the battery first, then ease the old battery out with isopropyl alcohol under the adhesive. Never pierce or bend a battery. Fit new battery adhesive and a new back cover adhesive so the phone closes flat and stays sealed.

Frequently asked questions
Will this battery fit my Galaxy A91?
Yes, if your phone is the Samsung Galaxy A91. Check the model number in Settings > About phone before ordering.
Does this battery have built-in protection?
Yes. It uses lithium-ion cells with protection against overcharging, overheating and short circuits, as on the factory battery.
Do I need to calibrate the new battery?
It is not required. Charging to 100% and then using the phone normally for a couple of cycles helps the battery percentage read accurately.
How fast will it arrive?
Orders placed before 4pm, Monday to Friday, are dispatched the same day from Manchester.
