I use this pulse-tech xtreme charger, it actually saved a few smaller alarm and lawn mower batteries for me and they have been great. a regular charger charged them up but the next day they were dead. the pulse charger revived them and they are alive a full year already..and I use it on all my cars even the daily drivers , I leave them on for a day.
I've had a great experience with the Pulse Tech too! I had a Yellow cap AGM not holding a charge and I was getting ready to toss it. SInce those batteries are hard to come by I thought I'd give this charger a shot and low and behold it saved it. It's been running for over a year and it was probably about 8 years old at the time.
