This battery tester meets my needs. Just something to tell me about the health of my battery bank without drawing power. It lights up when the battery is on and it seems to work fine. It's easy to read. However, it did not include instructions on how to program the device. There were no papers with the device. I had to guess which setting was the correct one and that was the one it came with. 12v, lead acid, that was the setting it came with.
