JPL batteries are long life design batteries. Normally in the alloy of plate, the percentage of Tin is 8%. For these batteries, we double the percentage of Tin in the alloy. Also we change the percentage the percentage of Ca in this alloy.

Valve Regulated Construction (Sealed)
These batteries are of the AGM (Absorbed Glass Mat) valve regulated (sealed) lead acid rechargeable type. The electrolyte is suspended in a specially formulated non woven glass mat separator. All the electrolyte is absorbed in this manner and provides a safe non-spillable battery.

Gas Recombination System
The gasses generated in the normal charge/discharge use of a rechargeable battery are internally recombined during normal operating parameters. In the fact in normal operational use, more than 99% of the gasses generated are recombined.

Safety and Automatic Valve System
If the pressure is over 2-5 psi the safety valve will automatically open and reseal. This promise that there is no any excessive accumulation if gas in the battery.

Heavy Duty Grids
The grids are made by heavy duty lead calcium tin alloy. This provides: Safety margin of performance condition, excellent recovery capacity from deep discharge, Extra service life in cycle application, Low self-discharge when it is not in working.

Operation in any position
Because SunStone batteries are sealed and all the acid is absorbed in the special separators, these batteries can be operated in both vertical and horizontal position.
