ALLOSUNGK503 12V Automotive Battery Tester, Charger Check, Alternator Check, Cranking Check,Multi Function Car Battery Diagnosis Handy Tool,Blue

Arrived today, Sunday, hooked it up to my spare tractor battery, and it works great. Saves me the effort to remove current battery (really difficult) to hook up spare. Thanks.

I like it; it is fast and easy to use. The only concern I have is that it gives limited information. It is not a meter, just gives a range. If it says 60% charged, I don't know if it is 60% or 79% because the next indicator is 80% then 100%.

It is great just what you need when your looking for that electrical problems I thought i had a bad battery but after replacing the battery it still went dead so i thought alnorator but with this tool it showed me it was fine. my 10 yo son found the problem he told me my brake lights were on while he was walking up the drive so i look and sure the brakes lights were on i thought brake switch but not even that .....brake pedal has a hole where switch push in the hole plastic plug well plug got old and dried out and fell apart....so ten cent plastic plug fix the whole thing but this tool help out a lot.

Worked one time then only lights up next to the "cranking check" mode instead of showing the percentage of battery charge. The battery is not in the vehicle so don't know why it is showing this (same as when it worked the first time so nothing different.) My battery charger shows a full charge. I used exactly as instructed multiple times. Unable to return it so money down the drain.

To check my car's battery and confirm its security to drive, I decided to buy a daily tool to test, not a professional one. I searched on Amazon and found this. As I said, this item is really suitable for the easy daily application. It is so portable that you can hold it and convenient to carry everywhere.

Works well. Would be better with a little more info on what all the lights mean, but it works.

To tell you the truth, I wasn't sure what to expect considering the price. Usually, you'll get what you pay for. Not here, folks! This is a great little gadget that does everything it's advertised to do. I'm really impressed!

The all-sun 12V Automotive Battery Tester was exactly what I expected and wanted. The only problem was two testers were ordered (and submitted on charge), but only was received on 10-25-17. Although the shipping carton was large enough to accommodate both only one was enclosed.

It is ok and easy reading.
