OPTIMA D1200+ 12 Volt Performance Battery Charger and Maintainer for 12v Starting Batteries Including OPTIMA Hypercore Lithium, AGM and Flooded Batteries

Highly recommend vehicle battery charger as it is very versatile for charging agm led acid and lithium batteries. It's got a very wide range of usable selections as needed.

So it still fires up and charges the battery.

This charger is working well. I like the digital readout and options available like AGM, deep cycle, maintain, etc. You do have to “select” what you are trying to do but it’s a single button push in most cases. Being able to ask it the state of the battery is useful. I have a 40 year old charger that still works but bought this for a new location, I’m glad I did. I may get another and put my old one on the shelf as an emergency backup, that’s how much I like it.

Not only are Optima Batteries the best, but they’re battery chargers are outstanding!They are great at charging up a battery or maintaining a battery while it’s not being used.I even had one of these big Optima chargers, go bad, for some reason, and Optima sent me another one right away!

This is the first charger I have ever owned that has really been well engineered. The handle and cord storage is great; the clamps are first rate (love the little light in my dark battery compartment on the boat); and the electronics seem to be very well done. I bought it because I my old Schumacher charger had died, and I had borrowed another Schumacher charger from my neighbor to charge a marine starting battery that had been heavily discharged by accidentally leaving the fishfinder on for a week. The borrowed charger simply would not recharge that $100 battery, apparently because it was so heavily discharged. After a string of cheap chargers, I went looking for a better one. This looked very nice and the reviews were good. When I got delivery of the new Optima, I tried it on that same marine battery. It analyzed it for a couple of minutes and then went right to work. I checked after 3 hours and it was still at only 50% of capacity, but by the next morning it was fully charged and it seems to work just fine now. I figure that the Optima just saved me half of its purchase price on its first job. I plan to use it to maintain my boat batteries over the winter. They don't do to well up here in northern MN. This looks like a winner.

Does the job for optimum battery

Great product , easy to use and the safety on it as well , let me finally use such device without feeling I’m going to electrocute myself or cause a dangerous accident.

So this thing is pretty great at battery revival. The maintenance is amazing. The down side is the "smart technology" outwits itself. If the intent is to maybe be able to start the vehicle off this when battery is totally dead, doesn't work.Read time on the battery is also a wait to expect.Overall it is a home run. It will bring a battery back that may barely have worked before, but it's not like the normal battery chargers that will start a motor from a completely dead battery.
