أداة اختبار بطارية السيارة ، أداة اختبار البطارية 6 فولت ، 12 فولت ، 24 فولت ، BM550

Great product, as soon as it arrived I checked the various batteries.

I tried at 60A and 240A. At 60A it's already a bit weak, showing both voltage and amperage in the higher range, and of course SOh. But at 240A it's the opposite; it's new and shows a lower starting value and lower SOh.

This is a repurchase. At the request of a friend, I skipped the first one and bought the second one. Since I have to set the cca value every time, it's inconvenient but I use it for cost-effectiveness. My battery is at 50, and my health isn't great. When first turned on, it lights up at voltage 12, okay. Then press up on the cca value to set the value, ok. If you press up and down, it shows health status, charging percentage, and resistance. v voltage comes out in this order If you bite it, you'll find out. However, we cannot certify if the value is accurate.<img width="120px" height="120px" style="margin:5px; border-radius:15px;" src="https://ae-pic-a1.aliexpress-media.com/kf/S93dd03a3f2264449a0354ac1c16b0aceP.jpg">

The value is a reference only, but it is sufficient to measure the health of the battery. With this function at this price, I think it's a good deal.

It can perform all the necessary measurements, and the measurement values are not much different from those of high-end models. It has sufficient performance for battery replacement and regular maintenance. The manual is almost useless, but the way to use battery testers is all the same, so you can easily find information online these days, so no problem!

seems to be of excellent quality<img width="120px" height="120px" style="margin:5px; border-radius:15px;" src="https://ae-pic-a1.aliexpress-media.com/kf/A02b80cf770874cf2a0ee1bca2ec13a66b.jpg"><img width="120px" height="120px" style="margin:5px; border-radius:15px;" src="https://ae-pic-a1.aliexpress-media.com/kf/A876e12419f844c4aa6ab069e0fd10da5S.jpg"><img width="120px" height="120px" style="margin:5px; border-radius:15px;" src="https://ae-pic-a1.aliexpress-media.com/kf/A7b1f196fabb148839ff5a903292b1fecQ.jpg"><img width="120px" height="120px" style="margin:5px; border-radius:15px;" src="https://ae-pic-a1.aliexpress-media.com/kf/A9e0ad58c45b84bbc971eaf3afabf825bQ.jpg"><img width="120px" height="120px" style="margin:5px; border-radius:15px;" src="https://ae-pic-a1.aliexpress-media.com/kf/A50f579d8db0643e8bf9aa3e5ff2a4f56Z.jpg">

The readings are accurate. There are no instructions, but the device is intuitive to use. The main drawback is that the device's calibration is done relative to the stated starting current of the battery, but if it's always specified for car batteries, it's not specified for batteries used in UPS or alarm systems... so it's impossible to test such batteries with this tester

It was easy to use. I recommend connecting it directly to the battery terminal. It's cost-effective.

A normal item, measures something. Made simply and with quality. I recommend it.
