6V / 12V Auto-Switching Smart Battery Charger w Float Voltage - 3 Stage Trickle Charger for SLA Batteries, Wildgame Feeders & More! by KeyLine Chargers

Very good charger for the price paid. Works great charging four parallel 6 v batteries in about 8 -10 hours. Fully satisfied with this product.

Works great. For my application I needed a dongle on the end, so I had to cut the clips off and add the single. I was disappointed in the guage of wires, primarily for my purpose of trying to solder the connection, but I would have liked to see at least 18ga wire on it.Charger works flawlessly, charged my deer feeder batteries with no issues. Everything is as advertised.

Does the job! The marketing photograph in Amazon shows charging a 9ah sla battery, but the instructions indicates it is only for 2ah - 5ah sla batteries. I contacted technical support and they indicated it will work fine, just take longer. Actually, I prefer that to a quick charger, because the batteries last longer. Indeed, it worked just fine. I do wish they made it with a slightly thicker wire (12 or 14 gauge), but then again, no other charger is made with thick wire either.

Bought in 2016. I used it occasionally to charge my sonar 12V sealed lead acid battery. Today it died while charging. Inside unit there was lots of corrosion, probably from leak of the electrolyte from the capacitors.

Very nice charger for the money, has a indication light to let you know when battery is charged. Have charged 6v and 12v batteries. Worked well.

Product works great! I really like the indicator lights on this charger. My old one didn't have those. The clips work great as well.

I have had the product for about a month and it has quit charging. I give it 2 stars because it worked nicely for the month it worked

Used to charge the breakaway battery for my horse trailer (12V battery). Started charging as soon as I plugged it in and connected to the battery, as per the instructions. However, after it finished charging (as per the LED indicator) I checked the voltage only to find it at a little over 6V. Repeated with same result. On the third or fourth try it finally realized it was a 12V battery and charged it to 13V. Although a hassle, I was just happy to have it charge since I needed it for my trailer to pass state inspection (the sole reason I bought it). Astarted others have mentioned, it won't charge a battery that is "dead-dead" (I had another battery in this boat). If you need something reliable you don't have to fight with, this might not be for you. However if it's a once-in-a-while or one-time thing where you have the time (and patience) to deal with the hassle, it does charge at the described pace.
