All DVS. I was looking for exactly the 30th model. After buying a "test drive" - ​​everything is as promised by the manufacturer! In summer, I added distilled water to the battery. In autumn, the belt whistled. I measured the density 1.22-1.23.- I bought a charger. Charged. The density has risen to the norm 1.26.1.27. I recommend the seller and the product!

After the big frosts (-43) the car did not want to start from the word in any way. I followed the instructions strictly (I connected the charger to the battery: negative terminal, then positive, then the network. 5 minutes of operation at maximum current. Then I violated the instructions: I didn’t start it with the charger turned on, but turned it off in the reverse order,) The machine started up.
