LUNDA Smart Battery Charger: Efficient 12V/24V Automotive Charger for Car, Truck, Boat, Motorcycle, and RV - 400Ah Maintainer and Trickle Charger Review

I think it's great for size and price. It charges the batteries quickly and then stops charging and goes to a service technician.

I had 2 12 volt batteries that were so weak they didn't register as batteries. The batteries took a while to turn on the charger, but when they did they fixed them and charged them to full capacity.

Small but works. I was curious and skeptical at first, but he did a great job. The machine is very delicate and requires certain skills (especially when loading in manual mode). But it's a fantastic option as it allows you to charge your battery up to 100%. The density of the acid exceeded the required 1.28 g/cm3.

The multimeter I use is very accurate. I have two of them and both give the same readings. I've seen it put out up to 9.3 amps, which isn't bad, but far from an on-screen display. For example, the display shows 15.5 amps, but actually only delivers 8.3 amps. It works well, I just don't like being lied to. I assume that a little more than half of the current readings shown are correct. Very light, very cheap. The potentiometer doesn't seem to do anything. An automatic or manual switch also seems

The suffix is misleading. This charger is 12V 15A / 24V 7.5A 180W. The digital display shows an incorrect battery voltage, 0.8V at 12V and 0.5V at 24V. The power wheel on the front does nothing at all , as far as I can tell. When connecting wires to the battery when it is disconnected from the wall, sparks will occur. The battery charging voltage is 14.7V. It works and charges the batteries, but I managed to charge 6 batteries at the same time, it doesn't have enough current to do the job I was
