1 Battery Monitor Basics

Why should I monitor my battery?

Batteries are used in a wide variety of applications; mostly to store energy for later use. But how do you know how much energy is stored in your battery? No one can tell you that by just looking at it. Some basic battery knowledge and good monitoring is essential if you want to maximize the lifetime of your expensive batteries. The lifetime of batteries is dependent on many factors. Battery lifetime is reduced by under-charging, over-charging, too deep discharging, too fast discharging and too high ambient temperature. An advanced battery monitor like the Xantrex Battery Monitor can give you important feedback about the performance of your batteries and help you extend their lifetime.

How does the Xantrex Battery Monitor work?

The capacity of a battery is rated in amp hours (Ah). For example, a battery that can deliver a current of 5 amps for a period of 20 hours is rated at 100 Ah (5 × 20 = 100). The Xantrex Battery Monitor continuously measures the current flow in or out of the battery so it can calculate the amount of energy removed from or added to the battery. But since battery age, discharge current, and temperature all influence the battery’s capacity, you cannot rely on an amp-hours reading. When the same 100 Ah battery is discharged completely in two hours, it will give you only 56 Ah. As you can see, the battery’s capacity is almost halved. When the temperature of the battery is also low, its capacity is decreased even more. This is why simple amp-hour counters or voltmeters cannot give you an accurate state- of-charge indication.

The Xantrex Battery Monitor can display both amp hours removed (not compensated) and actual state-of-charge. Reading state-of- charge is the best way to read your battery. This parameter is given as a percentage, where 100.0% represents a fully charged battery and 0.0% a completely flat battery. You can compare this to a fuel gauge in a car.

The Xantrex Battery Monitor also estimates how long the battery can support the present load (time-to-go readout). This is actually the time left until the battery needs to be charged again. If the battery load is fluctuating heavily it is best not to rely on this reading too
