Sealed battery

The sealed battery is also known as ‘valve-regulated’ or ‘VRLA’ (Valve-Regulated Lead-Acid). These batteries have the great advantage of being maintenance-free, which significantly reduces the costs associated with stationary battery maintenance. Although they generate gases like open batteries, these gases are vented to the outside through special one-way valves. This makes them ideal for installation […]
