abbout battery bro, anticounterfeit practices

***DANGER!!!*** We have found a significant amount of all lithium-based batteries for sale are fake and potentially dangerous. This includes those on Ebay, Amazon, Alibaba, and from some of the best-known suppliers both in the West and in Asia.

  • Some suppliers will salvage old, damaged batteries from laptop packs and repackage them with new PVC tubing (Grade C).
  • Some repackage brand name cells, but grossly exaggerate mAh and discharge ratings.
  • Some purchase bare cells and sell them without the required PTC and other safety mechanisms (which is technically illegal in US).

There are even dozens of accounts of counterfeit batteries exploding in the hands of customers causing serious harm, property damage, and lawsuits. The market is so flooded with counterfeit batteries, that even honest suppliers have a very difficult time knowing how to tell the difference.

We created Battery Bro to solve the problem by doing one thing and doing it well. We only wholesale Grade A, authentic, lithium-ion batteries. In particular we focus almost exclusively on the cylindrical 18650 battery and more recently have expanded to other types like polymer and specialized custom battery packs.

Battery Bro values honest and open information, prices, and easy access to free expert advice. We have established direct relationships with factories throughout Asia to source the best information, highest-quality batteries, and best prices for our clientele. 

The rechargeable revolution will radically change our world in the next decade. Join us, and let's spark a revolution together.
