Batteries of all types have a limited lifespan, even rechargeable ones. This can make things difficult since we all have appliances in our homes that are reliant on them. It is virtually impossible to judge a battery’s condition at face value (except where damage has become so severe that there are obvious leaks), and not everybody has the equipment on had that is necessary to get an accurate reading of your battery’s position in its lifecycle. Fortunately, there are a few ways to determine the charge and health of your batteries (however crude some of them might be). Keep reading to find out what they are, and how to do them.

Use a Multi-Meter

Mustimeters are used in a few electrical applications as a tool for measuring current, resistance and voltage. They have a range of uses, but are also well suited to testing the condition of batteries through a direct charge. While it is an effective and accurate means of measuring the exact condition of batteries and cells, not everybody is likely to have one on hand whenever they need it.

Physics is Your Friend

AA and AAA batteries can be tested quite easily with this simple method, although it doesn’t give you quite the accuracy of a multi-meter. Alkaline batteries fill up with a gas when their cells deplete, which changes the way they behave when dropped. A charge battery will likely not bounce when dropped a close distance from a flat surface, while depleted ones will make a blunt sound on impact and will bounce a few times. Do this by dropping the negative side (the flat part of the battery) face down and carefully listen to, and watch for its movements.

Compare Charges with Specifications

If you want to tell whether or not your batteries are truly on their way out, simply give them a full charge. Now take note of a few things:

  • How long did the battery take to complete its charge?
  • How long does it take the battery to be depleted from a full charge?

Now take the answers from these questions and compare them with the stats given by the manufacturer. If the margins are too wide, your battery is readying for a swan-song.
