How accurate is the CCA tester?

This simple tester is completely accurate, I own a battery store and I have some different testers, This is the most accurate to detect a bad cell, at the begining, there is one thing that this tester doesn't do: it doesn't test the alternator, but if you are looking for a simple accurate tester, it is your best choice.

I feel that the tester is quite accurate. If it is failing the battery, the battery is definitely junk. Sometimes it will pass a battery and the battery will start the car fine and is able to put out good cranking amps for a short time but then the battery may not have very good reserve capacity such as if the customer leaves their key on for a half hour the battery may die quicker than it should. But the age on the battery is a pretty good indicator for this sort of battery deterioration. It's a simple tester that works better than 2 others I have tried.

Accurate to more expensive machines. With any battery testing, one would have to know assumptive state of charge variables as well. The only downside, most warranty companies need a print off code and this ones only downside is it doesn't print or generate failure codes. But, for general testing, it ranks up there with the best and even takes abuse in the shop, as I have found first hand. If I broke it tomorrow, I would buy another. I compared it to others when I first bought it and was good. I had also had someone question it at a more recent date, and again was spot on.

Are you following the instructions properly when testing the CYA? If so, I would call LaMotte as you may have a defective unit.

It seems to be fairly accurate but would say it is probably within a few degrees of exact temperature. If exact temps are critical for your use, I would look for a product that guarantees accuracy.

The ambient temperature on mine appears to be accurate. It does short cycle like others have mentioned.

Ours is pretty accurate with the readings our physician gets. Make sure you follow all the suggested directions.

The first one I purchased seemed to be very accurate. The one I got more recently for my wife is far enough off to ruin your life. When mine is at 0.080, hers is at 0.065. When mine is at 0.100, hers is at 0.081. I contacted the company and they want me to send it back at our expense. This thing has been off since day 1. I know mine is accurate. I've had several BAC testers and I know when I'm close to the limit and shouldn't drive. I would not have driven when hers was at 0.065 and I was defiantly not close to legal when hers read 0.081.

This is NOT a load test device. Its Load indicator light will turn amber if the battery cannot maintain voltage. The Carbon Pile Load Tester by Cen-Tech, Item #91129 may be what you're looking for. It's about fifty dollars.

Don't know but probably not reliably. It would depend on the amplitude of the signals the tester uses to execute the tests and the nature of the circuit that the cap is in. There are lots of comments/blogs out there about this tester if you google around.

Ought to do just fine. 30CCA is within rounding error on 1000CCA and the scale is just painted on the face, the needle is free to go beyond 1000. I've had a couple of tests where I exceeded 1000 with no ill effects. That said, I wouldn't try it on a 1500 CCA battery

I think it is more accurate than the light one that come with the 8 cup pitcher. When this tester reads 009, the included light only tester stays dark.

Mine seems to give accurate readings...instruction sheet in box is fairly clear and easy to follow, even for an old timer like me.

These are the worst tests ever. I highly recommend retesting with a known brand. Good luck.

I have many times, with no issues, but you might want to check with the manufacturer for 100% accuracy!

This scale is related to the cold cranking amps of the battery you are testing. There should be a label on your battery telling you the CCAs. So if you are testing a battery with 400 CCAs then you read the needle at the 400 level. CCA is the amount of current a battery can provide at 0 F for 30 seconds and maintain at least 1.2 volts per cell (7.2 volts for a 12-volt battery).

Hello Kevin,This is NOT CCA. It is FUL copper. Thank you for your question!Taylor W.VIVO

I would say it is fairly accurate. However, I don't really let my motorcycle battery get that low to really determine how accurate.

I have no way to test, so am interested in your experience. I must say I had my doubts. sounds suspect to me!
