About Battery Load Tester
The slow turn-over that makes your heart sink when the weather turns icy is one of the things that you really do not like about that dual battery diesel dually that you drive for work on the ranch. Thank goodness for the battery load tester that allows you to determine which battery is weak before you end up dragging both batteries out of the engine compartment in the cold. The reliable sellers on eBay have a large inventory of six and 12 volt digital battery load testers that give you accurate load indications no matter what the weather conditions are and no matter which car, truck, or boat batteries need to be tested. The green, yellow, and red LED indicators let you know whether the battery is weak, bad, or good with just a quick glance at the tester. Red and black clamps attach securely to the battery's positive and negative terminals, and the starter motor test setting allows you to see if your starter is drawing too much current. A battery load tester means that you are positive of the battery status no matter what the weather brings.
