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.
