Review on 💡 Inteli-Power 4100 Series Converter by Progressive Dynamics: PD4135KV by Dre Bhatt

I've gone through several batteries in my van over the past few years. I was very surprised that after a year of use the battery just wouldn't accept it anymore. After a little research I found that the problem wasn't with the battery but with the charger. My old WFCO charger apparently charged them. Now, this Progressive Dynamics device uses a three-stage charging system. After installing this device and running its tests, it successfully revitalized my battery. Previously, the battery only held 12.2 volts. Now it holds 13.4 volts after one charge cycle. Good product!
