Title: OTC battery tester
Review: I bought this for $100 and I should have returned it. It says to test with ignition off which is interesting because it means it doesn't test the whole system and get hot like the load testers for $30.Manual says wait 3 seconds. Mine displays result immediately so I am not sure what it is testing. Manual says it displays "available CCAs." But mine does not. Instead I think you enter your CCA. It says "tt even compensates for cold temperatures," but instead you have to tell its cold temperature by pressing "cold test" button.The only useful information I got on my good 1 year old battery is voltage which you can getfrom a $10 voltmeter. The manual has clear english but information is very limited. It doesn't explain features and reasoning of why/how it works.
