## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice performance so far. (plus update
*by T***E on January 20, 2020*

Followed charging specs to set up my solar charger and the two batteries i purchased have performed per the discharge charts as i was hoping. The physical apearance seem higher quality than other batteries. I will update if anything changes.Update on 12/21/20. Very happy with these batteries. Buying 6 more today.

### ⭐⭐⭐⭐⭐ Last 10+ years when charged properly
*by J***G on March 16, 2021*

In 2008 I bought Fullriver batteries for my sailboat before setting out cruising. 4 of these DC400-6 batteries for the house bank and 1 each of the DC200-12 for my engine start and windlass. Cruised up and down the East coast for a couple years, staying in marinas half the time. Then in 2011 we set out for the Bahamas and the Caribbean - never staying in a marina. Our charging capability was running the genset to drive 3 smart chargers in parallel (125A + 2 x 75A), or a 190A alternator with external regulator on the engine, or 3 x 240W solar + 2 MPPT charge controllers. Once we upgraded the solar from our original 185W, we never ran the genset.We pushed the batteries hard - laptop computer running 8+ hours per day (wife was full-time consulting); sailed with autopilot + radar. We cruised full-time until mid-2013; kept the boat in a marina until 2019 when we hauled for a refit. The batteries performed flawlessly thru then. The batteries were kept up in the boatyard with a single 240W solar panel. Last year the charge controller blew and batteries finally gave up the ghost from being discharged for a year. I'll replace them with an identical set when we finish the refit and re-launch her later this year.The key is to never let AGMs sit for a period of time while not at 100% SOC!

### ⭐⭐⭐⭐⭐ Great Service
*by A***S on March 9, 2021*

Great battery. A little over priced but worked for what we needed @ the time.
