  • Brings back the dead.
Used this to try and save a battery in my lawnmower that hasn't charged for the 3 years I've had the mower. Ran the pulse repair mode overnight and it fixed and fully charged the battery. Not going to lie I expected it to be junk, but worth a shot for the price. Absolutely worth every penny.

  • Great Product but cables are short and flimsy. However, it works.
Great Product Works well. I used it to charge my MCI bus 8D 24 volt batteries. It took 1 day to bring them up @ 4amps and this charger got the job done. I was a little bothered by the very light weight cables and then they were short. The clamps are flimsy too. However it works but I will have to modify the lengths of the cable for my application so that I can keep the charger attached to my batteries when parked. I do like the LCD screen. It is easy to see in sunlight and at night. ... show more

  • Great Charging Device
Amazing, I bought this charger for an electric pallets at our warehouse. The charging unit went out and they wanted 600.00 for a replacement. Soon as it arrived I went to the warehouse. Hooked up the B-Qtech battery charger on the top battery which was wired in series with a total of 4 batteries. With the unit on 24volt and charging at 4amps by the morning all 4 batteries were fully charged. The electric pallet jack ran for 2 solid days before needing to be charged. This charger worked flawlessly. Thanks Steve ... show more

  • Used it often
I had a slow leak that I kept putting off having fixed (finally did) and this was great to use when I needed it. No problems, never failed.

  • The only instructions I received were in an oriental language so I have been feeling my way around.
Color: 12V Charger
Two big complaints. No instructions that were in English and it has very short cords. As near as I can tell it seems to work very well.
