Contact UsWhat is a Lead-Acid Battery: Everything you need to know
Valve-regulated lead-acid batteries (VRLA batteries), also known as sealed lead-acid batteries (SLA batteries): These batteries are sealed, meaning electrolyte cannot leak or spill out.

Contact UsWhen Should You Add Water to a Battery?
Optimal Timing During Charging Cycles. The optimal time to add water to a lead-acid battery is during its charging cycle. When a lead-acid battery is charged, the electrolyte solution (a mixture of water and sulfuric acid) breaks down into hydrogen and oxygen gas, which escape through the vent caps.. This process is called gassing, and it causes the …

Contact UsBattery 101: Your Guide to Lead-Acid Batteries
In sealed lead-acid batteries (SLA), the electrolyte, or battery acid, is either absorbed in a plate separator or formed into a gel. Because they do not have to be watered and are spill-proof, they are considered low maintenance or maintenance-free. SLAs typically have a longer shelf life than flooded batteries and charge faster. However, they can be more expensive.
