What Is a Marine Battery Tester?
A battery tester, simply, is a device that is designed to test batteries. You may have a car battery tester or a boat battery tester.. Some testers are even able to do load testing.
Why You May Need A Marine Battery Tester
It is always a good idea to test a battery to ensure that it is properly charged before you venture out onto the water. A marine battery gauge and tester can help to ensure you are not stranded. A tester can help you by telling you how much of a charge is on the battery and perhaps tell you if there are any potential issues.
Many question whether there is any real difference between a marine tester and a standard automotive tester. In most cases, a tester will work equally well when checking the marine battery voltage and car voltage. The biggest mistake is you want to avoid using an AC tester, because they are designed to test voltage for household or 120 voltage electrical items. Your car and your boat both need DC testers.
Difference Between Battery Meter and Load Testers
Typically, you have a choice between a battery meter and a load tester. However, there are some testers that offer a variety of fuctions. A battery meter will tell you when you need to consider charging a marine battery. Load testers are able to tell you how much of a load it is able to handle at that given time, which could be useful in helping you determine if you need to consider getting a backup battery to assist in running all of your boat’s electronics.
