We are here to help with concerns and questions about compatibility. Please use the contact us page on the website to get help before you place an order!

Does not work with H30

I purchased this battery as a spare for my acebeam H30 headlamp. It doesn’t work. The built in charger must be interfering with it.

This battery does not work with the H30 due to length of the battery. You need the Acebeam battery without USB charging built-in. We have sent you an email explaining this in detail and your battery options for the H30.

This thing is awesome. It does its job well. And a very handy built in charging port.

Wright battery for the job

Acebeem E70 requires this long battery so it doesn't break connection when the light gets bumped around & has enough continuous amp draw available to run on turbo. Each one comes with a nice USB to C cable that can charge your phone or tablet from the battery. No brainer.


This battery is so cool!!!!
