6 Frequently Asked Questions about “Lead-acid and lead-acid gel batteries”

Is a gel battery better than a lead acid battery?

If you don't mind the extra expense, a gel battery is a better option if you're looking into lead acid batteries. This is because you won't have to worry about maintenance. To summarize, here are the advantages and disadvantages of a gel battery.

Which battery is based on lead acid?

Both AGM and Gel are based on the lead acid concept discovered in 1859. The plates are made from lead and the electrolyte is acidic (see What is a lead acid battery for more detail on the structure of lead acid units). When lead acid was introduced commercially, it was revolutionary. This was the first battery that could be recharged.

What are the different types of lead acid batteries?

As we've seen, we have three key types of lead acid battery – flooded, AGM and Gel. But we also have them described variously as 'maintenance free', valve-regulated' and ' sealed lead acid (SLA)'. Depending on who you talk to, depends on which type of battery can be described which way.

What is a sealed lead acid battery?

Both are referred to as Sealed Lead Acid batteries but they have different constructions designed for different uses. Both AGM and Gel are based on the lead acid concept discovered in 1859. The plates are made from lead and the electrolyte is acidic (see What is a lead acid battery for more detail on the structure of lead acid units).

Is a flooded lead acid battery a wet battery?

A flooded lead acid battery is a wet battery since it uses a liquid electrolyte. Unlike a gel battery, a flooded lead acid battery needs maintenance by topping up the water in the battery every 1-3 months. Gel batteries are the safer lead acid batteries because they release less hydrogen gas from their vent valves.

When was a gel battery invented?

The modern gel battery was invented in 1957. Gel batteries are one of two sealed lead acid batteries, the other being an AGM battery. Sealed lead acid batteries are distinct from other lead acid batteries in that they are maintenance-free. What's in a gel battery? A gel battery is a dry battery since it doesn't use a liquid electrolyte.
