🔋 Battery Tender Battery Load Tester 12V/6V – Test Battery Load, Check Battery Health & Starter Motor Draw – 026-0020 Review

Easy to read and easy to use, digital has problems with wrong readings, they urge you to replace the battery while it's still good

This is something you don't use very often. I had a 12v battery that wasn't taking any load and this meter was able to confirm that. After that I was able to replace the battery with a new one under warranty. This has saved me a ton of money and may continue to do so in the future, albeit rarely. It's also $10 less than Wally World.

First you need to understand what this thing is. This is a voltmeter with a piece of wire connected in parallel with a switch. it contained some chemical from the factory's processing and produced smoke that smelled distinctly of burning tires. I suspect the wire was coated with some kind of chemical coating and when it got hot it started to burn and produce an odor. This thing works amazing, but the first few times don't use it in your garage without proper ventilation.
