6 volt 225 AH Deep Cycle Battery



This 6V AGM battery is a heavy duty, deep cycle battery ideal for back-up power and stored power applications. Affordable without compromising quality, this battery will provide power for years. This heavy duty rechargeable battery is made of AGM lead lead dioxide technology. The extra thick lead plates in this battery allow for a deeper discharge with less harm to the battery and provides 20% more charge/discharge cycles compared to other AGM batteries. This AGM battery has less instant energy, but greater long-term energy delivery. The dilute sulfuric acid electrolyte is absorbed by separators and plates, thus immobilized. Should the battery be accidentally overcharged producing hydrogen and oxygen, special one-way valves allow the gases to escape, avoiding excessive pressure build-up. Otherwise, the battery is completely sealed and is, therefore, maintenance-free, leak-proof and usable in any position. Perfect for applications requiring large amounts of power.

Starting batteries, such as car batteries should not be used for deep cycle applications because of the thinner plates in these batteries. They are more prone to warping and pitting when discharged.

You can connect these batteries in series or parallel depending on DC voltage needed.
