(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. ## Frequently Bought Together - Fullriver 903 L16 6V 415Ah AGM Sealed Lead Acid Battery DC400-6 - 10pcs 1 AWG-3/8" Battery Lugs,Copper Wire Lugs,UL Listed Heavy Duty Battery Cable Ends,Tubular Ring Terminals,AWG Crimp Wire Ring Lugs,Battery Terminal Connectors with 3:1 Heat Shrink Tubing - TKDMR 160Pcs Copper Wire Lugs AWG2 4 6 8 10 12 with Heat Shrink Set, 80Pcs Battery Cable Ends Ring Terminals Connectors Tubing Assortment Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/41731751-903-l16-6v-415ah-agm-sealed-lead-acid-battery-dc400](https://www.desertcart.vu/products/41731751-903-l16-6v-415ah-agm-sealed-lead-acid-battery-dc400) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
