# Quick Answer: How Many Years Does A 12 Volt Battery Last?

## Are 2 6 volt batteries better than 2 12 volts?

Re: 2 12 volt versus 2 6 volt deep cycle batteries number of charge discharge cycles.

If you’re comparing a dual 6-volt arrangement vs a dual 12-volt arrangement with deep cycle in both cases and approximately the same capacity and same quality on both sets, then the answer is no..

## Can you overcharge a deep cycle battery?

Overcharging Deep Cycle Batteries: As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.

## What voltage is too low for a 12 volt battery?

12.4 voltsWhen any 12-volt battery is discharged below 12.4 volts, sulfation begins to occur within the battery. Over time, this sulfation will diminish both the performance and lifespan of the battery. Regular use of a quality battery maintainer will keep batteries properly charged and extend their useful life.
