Schumacher ElectricBattery Charger and Maintainer, SC1299, 2-in-1, Fully Automatic, 0.8 Amps, 12 Volt, for Motorcycle, Power Sport, Car, and Marine Batteries

I have just started using this and it works great. This is my second Schumacher charger which I have owned for at least 50 years. This smaller maintainer/charger will mostly be used on my dual battery diesel truck that sometimes just sits for weeks at a time. It has been keeping both batteries charged just fine. I have also used it on 2 of my motorcycles to charge them up and again it did a good job. Schumacher is a leading maker of battery chargers and has been for many years. This maintainer/charger is half the price of other chargers and is just as good, if not better. Love it.

It recharged a car battery in about only 24 hours. I have set it up to maintain the same battery so it doesn’t go flat again. The charger I received was made in china. I find it a good value. Only thing left to see is how long it lasts. Works well with a battery measuring device to tell you how charged the battery is so you can gauge how much longer it needs to take to recharge.

Not sure what all the negative comments about cord length are. Maybe an older version? I got the SC1299 august 2024 and the cord is stupidly long. It’s 11ft. More than enough.I have used battery tender brand, NAPA and Nocos. Battery tenders are great, but ridiculous expensive IMO. NAPAs are good but my experience is only with larger chargers and not maintainers. Nocos are nice but kind of pricey. Enter this. It’s easier to use than anything else I have used as you just hook it up and walk away. No setting battery type, amps, etc. It does all the work. A simple LED light to tell you what is going on. If you are familiar with the Noco 1 it’s much bigger than that but you don’t have to set anything.CONS? When it is in float mode the LED light is off. So how do you know it’s plugged in and working? You don’t. So if you need a status LED like 99% of chargers and maintainers have? Look elsewhere.

I just received this item yesterday for my 12V Marine Battery on my boat, and I installed it today in less than 5 minutes. I placed this inside the battery box, on top of the battery, and with the included L bracket, and screws, it can sit on top of the battery, and it's held in place by the L bracket (placed in between the battery and the battery box). I didn't have to actually install it onto the battery or box for it to sit without movement. The ring connections (as pictured) were a little large for the screw terminals on my battery, but tightened down properly they still made good, soild, tight contact, and work just fine. I plugged this right into a 50ft extension cord that I run out of my garage, and over to where I park my boat, and it powered right on, and started charging. Other reviewers say that it's loud, but I couldn't hear anything until I put my ear to within 6 inches of the charger. VERY quiet. I also tested the ability to store it in the battery box in the configuration I said about before, and it fits just fine. When I unplug the charger, and lay the power cord on top of the battery/charger, I can close the battery box, and it closes just perfectly with everything stored inside. I recommend this to anyone that doesn't want to have to lug around a battery charger everytime you need to charge your boat battery, this can install permanently near the battery, and all you have to do is run an extension cord to your boat, and plug it in. It's literally like plugging in your boat to charge it, and once your done, you can just tuck all the wiring inside your battery box, and head to the lake. Other reviewers complained about not having a 12 ft power cord, but if you're going to permanently mount this on a vehicle, or boat, or whatever, do you REALLY want to have to wind up, and store 12 ft of extra cable SOMEWHERE on your vehicle, boat, mower, or ATV? That's alot of cable to have to stash somewhere, especially when there really isn't much room on a boat, Mower, or ATV TO stash that much cable. I love it. It works perfectly, great/easy install, and I don't every have to move or reconfigure it if I don't want to. I recommend this to anyone looking for a compact, permanent install trickle charger.

This. Floating charger works well. 2 downsides: low power = slow charging. Male plug incorporated into transformer is awkward in some illustrations. Cheap, but good quality.

This works so nice and has long wire leads with nice strong clips. Lawn mower batteries have tendency to die when you need them most. Just keep this hooked up when you are not using your mower etc. and your problems will be solved.When your battery is fully charged it cuts off, and you won't be using unnecessary power. Love it!

Works great to maintain the battery

Schumacher tenders are must have. I have these on lawn mowers, 4wheelers, tractors, semis, anything that not getting used daily. Keeps batteries charged up so they don't freeze during our -20 weather.
