I just recently changed my starting batteries; they were 4 years old!
I installed 2 new 8D 1400 cranking amp Everready batteries from Batteries +.
All of my previous starting batteries only lasted 2 years. I installed Power Pulse on these batteries when they were new and it doubled the life of them. I am very happy with Power Pulse; I have it on all 6 of my AGMs for the house.

PowerPulse 12 is the one I have. You just connect it according to the directions and you are go to go.
This really works!
