Schumacher Electric Battery Charger and Maintainer, SP1296, 3-in-1, Fully Automatic, 2 Amps, 6 Volt, 12 Volt, for Motorcycle, Power Sport, Car, and Marine Batteries

Husband bought this charger for his batteries. Said it works great and he’s happy with it.

Works well. Bought the manufacturer before and like it. So I bought another.

In my opinion these are the best maintainers on the market!!!! I have several of these, I use them on my boat, tractor, lawnmower they last & work great, NO DEAD OR WEAK BATTERIES 👍👍

I purchased this and two other chargers at the same time. The other two chargers cost less than the price of this, and worked equally as well; therefore, why pay more for same affects?Nice about this charger is the extras finished pig tale connector, so it can be easily attached to the batter axillary post, or use the other with clamps.

A great product at a great price

The old SM tenders of the same size were very heavy but made no noise when plugged in. Had them for 20 years. These on the other hand are very noisy when in use. They make a high frequency buzzing sound that is very obnoxious!!!I have 5 of these new ones in the garage and the Nosie and racket they make is very loud! Very disturbing when in the garage any length of time working on bikes, cars, yard tools, just makes me want to hit them with a hammer and put them out of their misery. Maybe I'll wrap them in some sound deadening material, but they might overheat? If you suffer from high frequency hearing loss you may not hear them. But I do!!!So I did try some sound deadening, helps some but the squealing sound still is heard. NOTE: This high freq sound is heard whether its charging or not. Just plugged in and they all start making noise.UPDATE 10/29/24 the float voltage has dropped on all 5 units. Was 13.2 volts float now all are at 12.6 to 12.9 voltage measured at the battery terminals. Recommended float V is 13+ volts. Going back to using my old ones and boxing up the 5 newer ones and storing away. What a shame.

Works as it should i have on my grand sons quad it keeping battery charged up

Defective and started out well but progressed to charge at over 16volts. Confirmed with voltmeter and other batteries and different brand of charger. Past the window for returns. Will buy a different brand to replace.
