Frequently Asked Questions

Rebuilding a battery sounds complicated. However, when you use the Battrx® DIY battery rebuild kit it becomes a quite simple process. You can DIY on site. Below, our battery experts answer some FAQ's about the Battrx® system, which is truly one-of-a-kind and is quite different from most other rebuild services that use solder tab options. If there is something that you do not see below click the red ?-mark and ask our battery experts.


Who should use our product?

The glorified home-owner could rebuild with our easy-to-follow instructions, however we are targeting the frustrated contractor who is sick of the weak factory-provided batteries that come with your power tools. Use our tools to open your battery case and then put our highest-quality cells in. You will never have to worry about sending your batteries to be rebuilt again.

What makes Battrx® batteries better than other Sub C battery replacement services?

They have never been soldered--100% mechanical connections BUILT IN at manufacture. Also, our Nickel Cadmium batteries are 2100 MAH and our Nickel Metal Hydride batteries are 3200 MAh.

Why is the Battrx® battery rebuild service different and easier?

Most other battery rebuild services use the solder tab option to rebuild rechargeable batteries. However, the amount of heat required for soldering is actually damaging the internal chemistry of the battery. Battrx® has engineered and manufactured premium quality batteries with tabs that are built in to the design--not soldered in as a second thought. Therefore, our batteries remain intact and are high-drain, high-current.

Also, some battery rebuild services requires that you send your battery pack to them, which takes about 4-7 days. Then it takes them some more time to rebuild your battery. Then it takes another 4-7 days for them to ship it back to you. That adds up to about 3 weeks time without your battery! Our system, on the other hand, does not require any back and forth shipping (which is bad for the environment, anyway) because you fix your battery YOURSELF, using our tools and simple-to-understand DIY instructions.

What battery-powered electronics do Battrx® rechargeable batteries work for?

Be creative! Battrx® batteries work for all C battery-powered portable electronic devices. Some ideas that we have come up with are cordless vacs (e.g., Roomba irobot vacuums, Roomba 500 battery, Shark Upright Vacuum, Dirt Devil), electric razors, electric transportation devices (e.g., electric scooters, electric bikes, Segways), adult remote control cars, RC (radio controlled) hobby cars and trucks, and power tools (e.g., drill batteries, Makita battery, Bosch battery).

Battrx® battery replacement rebuild 6v batteries, 9v batteries, 12v batteries, 14.4v batteries, 18v batteries, nicad batteries, nimh batteries, & and much more. You can even replace a sub c 2100MAH NiCd battery with a nimh battery for more power (3200 MAH).

What makes Battrx® technology and engineering cutting edge?

Heat and Solder is the usual way that battery rebuild connect one battery to the next to make a high-voltage battery pack. Sure, this makes for a strong bond between the physical batteries. But it actually weakens by the new battery because the amount of heat used for soldering will alter the replacement cell's internal chemistry (i.e., NiCd, Li-ion, or NiMH aspect).

Instead, Battrx® has engineered a rechargeable battery pack that is never soldered together--we manufacture new battery cells made specifically for connecting together, so there is no need to forge a connection using soldering--and therefore your new battery maintains shape and substance for its whole life.

Why do we believe in what we do?

Battrx® employees have spent years in the power-tool manufacturing industry and understand that the batteries that come in your power tool are standard quality, and designed for planned obsolescence. We have also spent time in the field, working with tools with weak batteries. We know that a weak, dying battery is detrimental and frustrating to contractors/owners. We deliver the highest quality batteries that last longer and make you more efficient.

We also believe in the economical and environmentally sound business model. Battrx® does not require expensive, wasteful shipping back and forth. Our batteries are premium quality you will only have to buy ONE, and it will last.
