TranzX Battery Cell Replacement Service

Posted on October 18 2018

Raleigh TranzX BL07 Battery

TranzX is a company that makes parts for a number of e-bike manufacturers, including batteries. When the battery dies though, replacements can be tough to come by. That's why we offer our rebuild service! Send in your battery, we replace all of the cells while re-using your case (so it's guaranteed to fit back in your bike), and send it back to you! Often, we can upgrade the capacity to give you longer ride time as well!

TranzX BL17

Here's the popular TranzX BL17 model battery that's used on iZip E3 Dash, E3 Peak, and E3 Sumo model bikes, along with the Raleigh Tekoa, Route, and Misceo, among others. It fits on the downtube. We can upgrade these from 417 Wh to 504 Wh with our 10.5 Ah rebuild.

Raleigh Sprite Battery

This is the TranzX BL07, a rear rack model, that Raleigh used on some of their electric bikes like the Retroglide, Superbe, and Sprint. We can also upgrade these to 10.5 Ah using our rebuild service.

    I have a 2015 Reliegh Takoa iE with the tranzX BL 17 battery. The battery is recently not lasting as long as it once did. How much would it cost to have it rebuilt? Upgrade cost?

    @Drew – In all likelihood, you have some dead cells that’s causing the battery to shut down early. We’d have to rebuild the battery if you want it working again.

    I have a tranzx 36v battery with about half charge in it but when I connect the charger the charging light stays green and the battery does not charge. The charger seems to be producing the correct voltage I can measure the pin outs on it.
