Motorola RAZR & Foldable Batteries

Two Very Different Phones, One Iconic Name

The Motorola RAZR name covers more ground than almost any other phone line. The original RAZR V3 launched in 2004 as one of the best-selling flip phones ever made, and a lot of them are still working today. Nearly two decades later, Motorola brought the name back on a foldable touchscreen smartphone, first in 2019 and again with an updated 2022 model. These are completely different devices with completely different batteries, so knowing which one you have matters more here than with almost any other Motorola phone.

Whichever generation you own, the signs of a worn-out battery look similar:

• The phone loses a noticeable amount of charge overnight, even sitting idle
• It shuts off unexpectedly while still showing 20% or more remaining
• Charging takes far longer than it used to, or the phone barely holds a charge
• The battery cover, hinge area, or screen feels like it's lifting or bulging

That last sign matters most, especially on a foldable, where a swollen battery can put pressure on the hinge and screen. Replace it right away rather than continuing to use the phone.

We carry batteries for the classic RAZR V3 and its variants, along with the RAZR2 series (V8, V9, and related models), and for the modern RAZR foldable released in 2019 and 2022. Every battery is cross-referenced against the original Motorola part number and phone model, and ships with a 1-year warranty.

How to Choose the Right RAZR Battery

Because "RAZR" covers such a wide range of phones, matching the exact model is essential:

• Check the battery number first, if you can. Look for a part number printed on the battery itself, like BK10 for a classic flip RAZR or NM50 for a 2022 foldable — that's the most direct way to find your exact match.
• Know which era you have. If your phone flips open with a physical keypad, you have a classic RAZR from the 2000s. If it's a touchscreen that folds in half, you have a modern RAZR foldable from 2019 or later.
• Match the full model name on a foldable. The 2019 RAZR and 2022 RAZR use different batteries, and the 2022 model uses two separate battery cells, so be sure you're ordering the correct one for your exact year.
• Know that installation differs by generation. Classic RAZR flip phones typically have a removable back cover, so the battery swaps out in seconds. RAZR foldables have an internal battery, so replacement usually means opening the phone's housing and may require prying tools and removing adhesive.

Frequently Asked Questions

How do I know if I have a classic RAZR or a RAZR foldable?

A: A classic RAZR is a flip phone with a physical keypad, first released starting in 2004. A RAZR foldable is a touchscreen smartphone that folds in half vertically, released starting in 2019. If you're not sure, check the model name in your phone's settings, or look at the battery itself and search for the part number here.

Will this fit my current RAZR (2023 or newer)?

A: Not currently. Our RAZR selection covers the classic RAZR V3 and RAZR2 flip phones, as well as the 2019 and 2022 RAZR foldables, but we don't carry a replacement battery for RAZR models released in 2023 or later at this time. Contact us and we can let you know if that changes.

How do I install a replacement RAZR battery?

A: It depends on which RAZR you have. On a classic flip RAZR, power off the phone, remove the back cover, lift out the old battery, and set the new one in the same orientation before replacing the cover. On a RAZR foldable, the battery is internal, so replacement typically involves opening the phone's housing and may require prying tools and removing adhesive. If you're not comfortable opening the phone yourself, a phone repair professional can install it for you.

Why does the RAZR foldable use two batteries?

A: The RAZR foldable's design splits its battery into two cells to fit around the internal folding mechanism. Both cells work together to power the phone, so if you're replacing the battery on a foldable RAZR, check that you're ordering the correct cell, or both, for your model.

Is it safe to keep using a swollen or puffy battery?

A: No. A swollen battery means the internal cells are breaking down, and it should be replaced right away. On a foldable phone, a swollen battery can also put pressure on the hinge and screen. Stop using the phone with that battery installed, and dispose of the old battery at a proper battery recycling location rather than in household trash.
