Jupiter Batteries has decided to offer Deep Cycle AGM (Absorbed Glass Mat) batteries exclusively.  Due to the depth of discharge and the number of discharge cycles that are typical of UPS, emergency lighting, solar, alarm and similar applications, only Deep Cycle batteries, with their heavy, solid, nonporous lead plates will withstand the test of time.

In addition to the use of solid lead plates, Jupiter Batteries utilizes the best of AGM technology.  AGM batteries are unique in that they use mats, woven of very fine boron-silicate glass fiber, to hold sulfuric acid between lead plates and act as a highly-efficient transfer medium for the chemistry that is a battery.  Because the glass mats are only 95% saturated with acid, the problems associated with free liquids are eliminated. 

Thirdly, our AGM batteries are also VRLA batteries (Valve Regulated Lead Acid).  As such, they are recombinant, i.e., they operate under a slight pressure and force the oxygen and hydrogen that is produced to recombine into water.  This process is so efficient that very little water escapes over time and, consequently, there is no need for any to be added. Other important reasons that we recommend only AGM batteries are provided below:

• No spillage if an AGM battery is dropped
• AGM batteries are classified as non-hazardous
• An AGM battery can be mounted in any position
• An AGM battery will not freeze
• Our AGM batteries release very little hydrogen gas and only under a heavy discharge
• Charge voltages are the same as other standard batteries
• The internal resistance of an AGM battery is low.  Therefore, less heating occurs during charging and discharging
• AGM batteries possess wide charge and discharge current ranges
• AGM batteries have very low self-discharge rates, normally <3%
• Our AGM batteries are cost effective
• Deep Cycle batteries are capable of withstanding a large number of deep discharge cycles without loosing capacity
