Review on ⚡️ PP-12-L PowerPulse Battery Maintenance System – PulseTech 12V by Ricky Mayo

I was using a heavy duty deep cell battery that was well below its "empty" voltage and I was concerned I had just wasted a few hundred bucks. At first the solar panel didn't want to fully charge the battery. But after connecting one of them to the battery, it soon showed more than 13V again. I am also planning to use one of them on my car batteries to extend their life and save more money. The future battery will cost more than the price of the device itself.
