Review: MUY BUEN PRODUCTO Review: As user Chafik said this doesn't give the correct SOH or SOC because it isn't taking into account the temperature. For example: I used this at +5 deg C today and it was reading 12.49V. But when I ran the tester it was saying my SOC was something like 68%. Why? That isn't remotely correct. A battery at +5C has a max charge of 12.501V meaning my SOC was closer to 99.9%. It was reading my CA as 760A and my CCA as 560. Bear in mind neither of those numbers are the true CA or CCA since this device doesn’t correct for temperature. You can estimate your CA and CCA using what this device gives though. It’s fairly easy using excel. CA is determined at 0 deg C and CCA determined at -18 deg C. CCA = CA/1.25 (which is all this device is doing when you switch between CA and CCA modes). Ignore the SOC and SOH %’s this device gives they are irrelevant and incorrect. So go in excel and plot your x-axis as temperature. Test your battery in CA-mode for your first data point. So for me I put +5C as 760A. and “CCA” is 18C lower than CA so I put -13C as 560A which I got by testing my battery in CCA-mode. Plot a trendline and you can calculate your true CCA and CA. My true CCA is then 504A and my CA is 704A. The device was telling me my SOH was 100% but in reality it’s closer to 97% since my battery is rated as 520A CCA. Taking more readings would make it more accurate of course. Update as of December 2025: Still using the same product today. Still works great. As long you plot the data as I mentioned above with x-axis as temperature, y-axis as amps, you'll get the right data. Just a tip: you need to let your battery adjust to ambient temperature. Lead acid battery containers are ABS which is a bit of an insulator. If you turn your car on, boost your battery, or charge your battery, the liquid in the battery will be hotter than ambient thus skewing readings even if you do the corrections as I noted. I see a lot of negative reviews and most seem related to not taking into account as to how much temperature affects battery chemistry. A hypothetical battery fresh off the production line with brand new lead plates charged to 100% will read as 0% health, 0% charge at -55 to -65ish celsius (the freezing point of battery acid). You either wait for ambient to match CCA or CA or you plot some graphs. ## Features - 【Reliable Automotive Car Battery Tester】 KW208 is the most cost-effective battery tester compared to other brands, it has all the functions you need and the lowest spend that you can afford.
