Accumulator, I have been using different testers for many years, including not cheap Coulomb 12 ns, SKAT-T AUTO and others. But this tester works out its price perfectly. Especially data on the internal resistance of the battery and Cold scroll current. Definitely worth your money. Helps identify emerging problems with your battery, plate sulfation and loss of residual battery capacity. Useful for maintenance and battery maintenance. There are functions for checking the operation of the starter and generator of your car. Not a professional device (at a price of tens and hundreds of thousands of), but for this price, it will become an effective assistant. I can recommend to buy. The main thing is to understand how much you need it.
