    Easy to use & very straight forward

    I bought this based off a review that I saw of the product by youtube Scotty Kilmer, the tester is easy to use & the screen is very clear, it even comes with a small instruction manual. I wanted to get something that I can use to check the status of my own battery before it goes bad but this item also checks the starting system as well which is good. only time will tell how it holds up because you probably won't be using it all that much.

  • Most critical review

    I was disappointed in this battery tester will not test deep cycle battery's.

    It test CCA of a CCA ranked battery. It will not measure the Amp Hours of a deep cycle battery, which is what I need to do.

  • Cost effective battery/starter/alternator tester

    The tool indicated my battery CCA and starting voltage were low which was confirmed by my mechanic when I took my car in to have the battery replaced per the recommendation of this tool. The tests were listed in the order they should be performed on the screen of the tool. Screen prompts were clear and easy to follow. The results are summarized with clear recommendations such as "GOOD BATTERY" "GOOD-RECHARGE", "REPLACE", "BAD CELL-REPLACE", and "CHARGE-RETEST". It tells you the internal resistance of your battery, the state of charge as a percentage of full charge, the calculated available current in accordance with 10 standards including CCA, battery life as a function of available current compared to nameplate available current, the minimum voltage when starting the vehicle, the time it takes to start, the health of your alternator based on ripple voltage and charging voltage, and if you have a bad cell (no load voltage lower than expected). The tool works with various battery types including flooded, AGM flat pate or spiral, and gel.

  • Nice, compact, intuitive, easy to use & store

    So far, so good. It confirmed the good state of a good battery in a 1 year old car and recommended to replace a 7 year old battery and confirmed the bad state of another battery that had been used as a backup for a UPS. I hae not used it to check start the car diagnosis or alternator functioning. It replaces a bulky tester that put a huge load on the battery and did not give anywhere near reliable results. I like that it is compact and fits into a drawer readily. The manual is a bit vague, and the English is is not the best. As manuals and tools can be readily separated, it would have been nice if abbreviated instruction could be on the instrument or a "tag" on a cable which is a common practice for many household small appliances. Timely shipment, packaging was adequate.

  • Batt tester

    Once you know your battery specs there battery tester us pretty self explanatory. I was checking a low batt when cranking. You can see if the alternator is charging, standing batt power as well.

    Great product. Pays for itself the first time that you use it on a battery tha you think is bad but just needs charge

  • Glad I bought it.

    This little item does a great job, I have been in the generator/starter/alternator business before, and to do a similar job as this tester does, I would need a carbon pile and a half an hour of time. It does a good job of agreeing with my assessments so far, and I am really glad that I bought it.

  • Really good product.

    This tester is quick and easy to use. Very good value. It is less expensive than one I purchased 11 years ago. This one does more too.

  • Saved me from getting stranded with dead battery.

    Use this to check your batteries every year before winter and it will keep you out of trouble. My car was starting good in cold weather but this said the battery was bad. I took it into Walmart and they said it was bad and I got a warranty replacement.Saved me trouble so I didn't wait until I was stranded somewhere to have to get a new battery.
