Digital 1200 12V Performance Battery Charger and Maintainer - 150-33508

This is what you need to maintain your Optima batteries and keep them going for years to come! I recharge mine about every 10 months and it’s been working great for years! Highly recommend this for anyone who wants to bring an Optima back to life or just maintain yours. For Optima batteries mainly but will charge any battery I think? This thing is easy to use and has worked great for 3 years for me. I love it

This is a very advanced and versatile charger. It's able to charge Lithium, AGM and Flooded batteries. Perhaps my favorite feature of this charger is the easy to read graphic display that shows you at a glance the state of charge on your battery and gives you an indication of how long it will take to charge a battery. It also has a boost / quick charge function to aide in faster charge times but it's not intended for engine starting. I have been using CTEK chargers for the longest time but I wanted this one for its ability to charge Litium batteries and its LCD display. I hope this charger stands the test of time because it's not inexpensive. Time will tell...

I got one of these because my neighbor let me borrow his. One of my cars had the battery completely die on it. The battery was about 5 years old so it is what I would consider near the end of it's life AND i don't drive the car a lot. I pulled the battery out and put it on this charger. It took ~12 hours for it to fully charge and go to maintenance mode. The battery has worked like an absolute champ ever since. The cost of this is slightly prohibitive/steep. But compared to the $40 ones you find at the part store... it does a lot more and performs WAY better. So it certainly lives up to the price.

I've used several different battery chargers with my Optima Yellow Top battery over the last few years. And they've all seriously disappointed me. One will quit charging randomly before the battery is fully charged. Another doesn't switch to trickle charging when the battery is charged, leading to possible over-charging of the battery. I'd rather not have to babysit a battery while it is charging, thank you very much. This charger doesn't have those problems. You just hook it up, select the mode you want, and walk away. It regulates voltage and current properly to both charge the Optima (or other) batteries as quickly as possible, while doing so safely. My only complaint with it is that the cable compartment at the back is just barely big enough to hold the charging cables. So it takes a while to properly fold the cable to get it to fit. Even if it was just a little bit bigger storing the cable would be quite a bit easier. But other than that, it's a fantastic charger. Now, if only the price weren't quite so high...

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.

This is an excellent charger! Works great on my yellow top, my secondary standard battery, my mower, and soon I bet it'll see the Harley battery. I'm charging all of them with this now. Real simple to use. Connect the battery, plug it into the wall and push a button or two. It tells you the battery life after a 5 mins evaluation, then starts charging and tells you what amp and voltage it is at. I'm super impressed. I bought this to have a nice charger around, and the guys at Optima charged a battery for me at a car show years ago with this same charger. Gave it back to me in just over an hour and said I was good to go, and that battery got me through the rest of the show!

So it still fires up and charges the battery.

Nice charger and easy to use. Only this don’t have fast charge to start the engine. This design was to keep battery from over charging to protect any size of batteries. I really like the style that look cool and easy to understand after reading the manual to learn how to operate properly. Also price is expensive without fast charge for emergency needs.
