Customer Reviews

This device is a carbon pile load tester.
A carbon pile load tester works by applying a calibrated load to the battery (the load is essentially a large carbon resistor that heats up when voltage is applied).
To properly test using this method, the battery must be at least 75% charged. A good battery should be able to supply half its cold cranking amps (CCA) rating for 15 seconds without dropping below 9.5 volts (if you want to test batteries that are not fully charged you'll need to purchase an electronic tester which tests by measuring the internal resistance of the battery.)
IMPORTANT NOTE: This unit (by design) will get hot and might initially produce some smoke if there is any foreign matter on the resistor element.

Besides checking batteries on my car and truck I have several other deep cycle batteries for RV and other purposes. This unit provides an easy and quick way to know if the batteries are healthy and expected to last awhile. Yes, the tester did smoke slightly during it's first use, but it's expected to 'burn in' when new, like a muffler on a new car. The BT-100 looks and feels like a quality piece of equipment, is handy to have around and a good buy from Amazon.
