These are the 200 AH 12 Volt AGM Sealed Lead Acid Batteries from Vision. There's a reason why we almost exclusively sell them: they work. Quite well too. These batteries have an extremely thick lead mat allowing for the voltage to be maintaned, even if the batteries are down 60-80% of their capacity, giving our inverters a longer run time where other batteries just won't cut it.
These batteries are heavy. Weighing in at 144lbs, these aren't really meant for pick-up and go mobility, but instead are excellent for RV's, Food Trucks, Work Trucks and Whole Home and Commercial Backup Systems.
Affordable high quality batteries. Our rechargeable batteries are leadacid dioxide systems. The dilute sulfuric acid electrolyte is absorbed by separators and plates and thus immobilized. Should the battery be accidentally overcharged producing hydrogen and oxygen special oneway valves allow the gases to escape thus avoiding excessive pressure build-up. Otherwise the battery is completely sealed and is therefore maintenance-free leak proof and usable in any position.
Note on Depth of Discharge: We rate our use and longevity at 50% DOD; saving the customer money on initial battery purchases. For a much healthier, longer lasting system, it is our recommendation that you purchase enough batteries with an anticipated rate of 30% depth of discharge.
As you can see from the chart, the cycle life of the batteries increases more than double, by merely adding a few more batteries and discharging them the same you would. This eventually will save you the most money in the long run and increase your battery longevity.
