TranzX Battery Cell Replacement Service

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 up to 14 Ah using our rebuild service.

    We have TranzX Battery BL07
    Product Model:305166
    We have put it on charge after a a couple of years of no use and we have no lights to confirm charging and is there a way of checking? Does this mean it wont/ or can not charge. To replace is high so what is the cost of a rebuild, and the time scale.
    Thanks Pete

    @John – We have some used cases we can salvage a lock and key from, but we don’t have spare keys.

    I have a Raleigh Bike with a BL07 battery and I lost the key. Can you get me a replacement key?

    Thanks
