Optimate 7 Select - 12V 10A, TM-251v3, 9-Step Gold Series Battery Saving Charger & maintainer

Excellent equipment works as it should

Have owned for a couple years now. works great, simple to use, doesnt over charge, Lets me know battery condition/ life strength. Lets me service cars with the batter dead, removed or without draining it over prolonged key on situations. I LOVE THIS CHARGER. Compact and high quality instead of the giant metal rolling boxes that all seem to fail and dont even smart maintain!. This unit downshifts to maintenance after a charge or indicates if the batter is going bad. Only missing a high power jumpstart mode... whichis understandable in a small compact unit with sensors and and lower power maintenance switches. I will be buying this for brothers garages and hobby shops.

I'm glad I finally invested in a quality battery charger to replace decades of using a cheap maintainer (Battery Tender Jr.) and a walmart battery charger (Schumacher 6-amp), the Optimate 7 was exactly the upgrade I needed. Being a full-featured 7 amp charger, I was skeptical that it would make sense to use as a maintainer, especially on a small motorcycle battery, so I monitored both its power use at the wall using a Kill-a-Watt EZ, and its voltage output at the battery using a multimeter. Interestingly, once it goes into maintenance mode, it uses almost no power most of the time, reading 0.0W at the wall, by contrast, the Battery Tender Jr. reads a few watts any time it's plugged in, even if not connected to a battery. For the price it seems like there should be a more informative readout on it, like an LCD that tells you exactly what it's doing in plain English, but the LED light method is effective once you decode what each combination means, and it's likely for more bulletproof for anyone preferring to buy it for life. Don't be tempted by cheap junk like Noco that offer a lot of features but fail after a year or two, and may not be delivering as "smart" a charge as they promise.

Have had an Optimate 4 for years and this one has more features and higher output . Just hook up to battery and they will do the rest. Diagnostic panels will keep you informed what is going on and condition of battery. In my experience they do best job of fully charging and maintaining batteries. Will recondition and charge batteries that other chargers I have won't even try to charge. If could would give 10 stars ?

Second one I bought for our Work shop! Amazing Save feature for batteries pays for it self! Recommend! I had one of these since 2011 and has never failed us. Bought another one to keep our growing battery needs met with all our machines. From 2020 YAMAHA, XYZ 1000 SS R to our 2021 KAWASAKI Teryx S LE, to our 2017 YAMAHA Grizzly 700 Limited Edition to our 2016 YAMAHA Kodiak 700, Grand Caravans, Snow Blowers(electric Start) everything requires a Battery Tender when it sits for sometimes months between uses. This Battery Charger, Tender, Saver, Optimizer is Incredible. Any Battery Type, it Auto Detects and Protects it! This unit has taken batteries from what we thought were Done, Nothing but Core's and revived and saved the batteries and have been used for years after! It earns it keep and saves you hundreds of dollars in EXTENDED BATTERY LIFE, Highly Recommend. Hope this helps!
