NOCO Genius GC015 12V Eyelet Battery Indicator

The battery will barely start the car and this thing says it has a 100% charge. I hooked up a NOCO charger to the battery and it said the charge level was 25% while this thing was still a happy 100%. According to this either the battery is dead or it's 100%. Pretty worthless.

I use this to monitor my generator start battery. So far it seems to be working well. The battery was already charged. When I hooked it up to the battery the green light was blinking. I zip tied it where I can see it easily inside my battery compartment. Perfect. Thanks!

Got this for my NOCO Genius G3500 6V/12V 3.5A Automatic Multi-Purpose Battery Charger and Maintainer (Grey) I purchased several months ago. I have been swapping the charger around to several different vehicles, so I thought I would give this accessory a try. So far, I really like it. You can quickly tell if your battery needs charged. Going to go back for more to install on all my cars.
