What are SLA batteries?
SLA are Sealed Lead Acid batteries with basically the same chemistry as a wet (flooded cell) battery. The batteries’ electrolyte is in a gelatin form and is absorbed into the plates and the battery is sealed with epoxies. These batteries may be used in any position and the batteries are exceptionally leak resistant. Battery uses are UPS, emergency lights, Telecommunications, and camcorders. These batteries are 2 volt per cell so the common batteries are 4, 6, and 12 volt.
