  •   Your local car shop can not only load test your Sealed Ups Battery for you. But it is easy to do at home. All you need is a digital voltmeter. In order for any load test to be accurate, the Sealed Ups Battery must be fully charged. Let's take a motorcycle battery as an example:

      Remove the seat and expose the Sealed Ups Battery in the bicycle so that you can use the terminals. Do not disconnect the battery, because you will try to start the bike.

      Fix the pins of the voltmeter to the correct terminals on the battery.

      Now press the start button and observe how far the voltage drops. It doesn't matter whether the bicycle is started or not, what you are looking for is the voltage reading.

      A healthy Sealed Ups Battery should maintain a range of 9.5-10.5 volts for 30 seconds under load. If the battery starts to hold and then the voltage drops steadily, there is a problem. If the voltage drops to 0 volts instantaneously, that is also a problem. We call it an open-cell. On new batteries, this may be the result of manufacturing defects, but it may also be caused by the accumulation of sulfate crystals.

      Under the intense heat of the load, one or more weldments connected to the battery loosen and separate. This will cut off the current and the voltage will drop. When the battery cools, the fragments will come in contact, and it can hardly be fully connected. This will give you an incorrect voltage reading. Batteries with open-circuit batteries may read a full charge when they are not in use, but they fail the load test every time. Once the battery reaches this point, there is no turning back. The best way is to recycle this thing.
