Measuring Batteries Doesn’t Sound too Bad, Right? This is the basic theory for most battery monitors you see on market. For instance, if you have a 100Ah battery and your battery monitor measures 25Ah taken out, then you would know that you have 75Ah left in that battery. This lets the internal cells balance out properly, assuming they’re all in good condition.Īfter that’s done, you measure the Amps that are put in and taken out over a period of time to know how Amp-hours are in your battery. To be sure the battery is 100% full, you need to give it a 3-stage charge and let it sit for 12-24 hours without being used.

This is similar to counting how many cups of water are being poured out of a full container to know when it’ll be empty. The next logical step is to fill the battery all the way up as a starting point, then keep track of how many Amp-hours are used to know how full your battery is at any point in time. That scenario isn’t common though, so let’s look at it when you’re in control of more variables. You’d need to be able to let it sit for 12 hours to balance and level out as well as have a machine that can load test it or use a hydrometer if you’re lucky enough to be handed an FLA battery. There isn’t a measurement that you can take to that can tell you this.

If you were handed a lead acid battery off the street, it would be quite difficult to tell how “full” it is on the spot. Let’s first look at what can’t be measured realistically from a battery.
