Review on LST Truck Battery Charger Maintainer: Auto Trickle Deep Cycle Charging For Automotive, Marine, RV, SLA ATV AGM Gel Cell WET Lead Acid Batteries by Jeff Jackson

Seems to work great, only reason I didn't give it a 5 star is every day I plug it in and in plug it and when I get home and plug it in again it automatically goes to 24 volt and it won't let me change it with the mode button unless I take the gator clip off the terminal then switch to 12 volt then place it back on the terminal. I wish there was a manual toggle switch for 12 to 24 volt, instead of the push mode button. Its quite a hassle.
