DieHard Microprocessor - Controlled Battery Charger and Tester, 80 Amp Engine Start —
I have owned this unit for 3 years. Still performs and provides read outs as expected. I use it all the time between 2 suburbans, a boat and a motorcycle. Paid for itself several time over from not having to buy batteries ever other season due to down time on the battery. Great to have a unit that reaches 100% charge then you do not have to worry about disconnecting as this unit stops charging once you reach 100%. awesome unit!
