    Rated 5 out of 5 by from Works Magic Had four old Optima batteries around the shop ranging from 1-3 yrs old. Two red top and two blue top. Regular charger would not bring them back and auto zone said they were toast. Bought this bc of a recommendation from a guy that worked there. Works like a charm.

    Rated 5 out of 5 by from Great features. I have purchased several of these chargers to maintain the batteries in my antique cars and trucks. They do a great job of extending the life of batteries that aren't used often. I only wish they made a charger that worked on 6 & 12 volt batteries.

    Rated 5 out of 5 by from Small package with big features Have had another manufactures maintainer for years but only display were some red/green lights. Worked OK but not very informative on battery condition or charge rate. OPTIMA tells me all I need to know with its displays. Keeps the fleet of classics all ready to start and greatly extends battery life

    Rated 5 out of 5 by from Worth the price! Picked up my 5th Optima to replace a 6yr old Yellow Top. Traded in a older Red Top for a new Red Top that got hot using and never held a charge with my CTEK charger. Tried out this Optima 400 on my new Red Top after my CTEK charged it and found out the new Red Top was only 75% charged. Put the Optima on the new Red Top and it charged up to 100% capacity & maintenance mode. Next tried to charge my old 6yr Yellow Top deep cycle that wouldn't hold the charge before with the CTEK. The Optima 400 seems to have charged it to 100% and now in maintenance. So far, so good - it's 2 for 2 with the Optima 400!

    Rated 5 out of 5 by from Well worth the price I was recently disappointed by another brand of trickle charger that I had used for years on various cars and motorcycles. Although the Optima unit was twice the cost of the other brand I'd been using, I went ahead and tried it. It's simple to use; after all, it's a trickle charger, right? After selecting the battery type, the Optima's display gives you all the information you need on your battery's charge status. This unit also includes a wall bracket, quick disconnect attachment leads for your battery and a set of high quality clamps on a quick disconnect lead. I use the Optima Digital 400 to maintain a full charge on a group 24 flooded cell lead 850CCA battery.
