They’re usually converted to amp(ere) hours (AH). Amperes are the measure of actual power available. This is your starting point.Īs mentioned earlier, you should only draw a battery down to about 12.3 volts before recharging. As it does, the electrons distribute themselves and eventually balance out at 12.6 volts (more or less, depending on the type battery and its condition). The typical wet-cell battery (lead plates in a mixture of sulfuric acid and water) needs to be charged up to about 14.+ volts in order to adequately distribute those funny little things called electrons through the plates. When checking the batteries, (at rest) use these “Voltage Landmarks”. To charge a standard 12-volt battery, you have to bring it up to above 14 volts (amount varies with the type of battery). You have to force more electricity into a battery than it would like to accept or it won’t be fully charged. Similarly, batteries have an inherent resistance to take a charge because of their chemical makeup. The wire you pump electricity through and the connections in the lines resist the flow. You have to have more “juice” at one end of a wire than you need at the output or electricity won’t flow. Electricity doesn’t, it has to be “pushed” (just as water has to sometimes be pumped). This is okay up to a point, but water also flows by gravity. Some more basics: If you read articles on how electricity flows, you see comparisons as to how water flows. Watts = Volts x Amps example: 60W = 12V x A and 60 ÷ 12 = 5 ampsĬharging voltage is different. They know that, if resting voltage ever reaches 12.1, they have deep-discharged one cycle and that a battery is good for only so many cycles (from as low as 20 in an automotive battery to 180 in a golf cart battery, with the typical RV/marine battery good for no more than 30). They never use more than 50% before recharging (resting volts of 12.3) except in an emergency. That means they never let resting voltage get below 12.5. Experienced RVers try to use no more than 20% to 50% of the energy available in a battery before recharging. The lowest limit is 10.5 volts (used in testing) and obviously unsatisfactory in practical use. No 12-volt battery will remain at over 14 volts for more than seconds unless it’s being charged.

It’s either a goner or it has been deep cycled, and a battery can only be deep-cycled a limited number of times before it is indeed dead.ġ2-volt batteries supply useful energy only through a limited range - from over 14 volts (when fully charged and unrested) down to 10.5 volts in use/under load (when lights dim, pumps groan and TV pictures get small). Actually, if a battery’s resting voltage is only 12.0 to 12.1 it means only 20 to 25% of its useful energy remains. When a battery reads only 12 volts under the above conditions, it’s almost fully depleted. A fully-charged 12-volt battery, allowed to “rest” for a few hours (or days) with no load being drawn from it (or charge going to it), will balance out its charge and measure about 12.6 volts between terminals.
Twelve volts is just a nominal, convenient term used to distinguish one battery from another. A 12-volt battery is not a 12-volt battery.
