How does a Gel or AGM (VRLA) battery work?
VRLA batteries are designed using proven gas recombination technology which removes the need for regular water addition by controlling the evolution of hydrogen and oxygen during charging. This means that the oxygen normally produced on the positive plates of all lead-acid batteries is absorbed by the negative plate. This suppresses the production of hydrogen at the negative plate. Water (H20) is produced instead, retaining the moisture within the battery. It never needs watering, and should never be opened as this would “poison” the battery with additional oxygen from the air.
This feature makes VRLA batteries ideal and the first choice for cyclic applications that are indoors, used in enclosed areas and/or used near sensitive equipment
CAUTION/DANGER
Lead-acid batteries contain a sulfuric acid electrolyte, which can be poisonous and is highly corrosive. Flooded Lead Acid batteries will produce gasses when discharging and re-charging which can explode!
When working with batteries, you need to have plenty of ventilation, remove your jewelry, wear protective eyewear (safety glasses) and clothing, and exercise caution.
Do not allow battery electrolyte to mix with salt water. Even small quantities of this combination will produce Chlorine gas that can KILL you!
