Review: Quality, Compact, complete. - 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.
Review: A True "Smart" Charger Built to Last - 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.

### ⭐⭐⭐⭐⭐ LOVE the Power Supply Setting!
*by K***L on November 23, 2025*

This replaced an Optimate 3+ that I’ve owned and used for the past 11 years. Nothing at all wrong with the 3+! But I wanted a charger with a power supply mode, so I could use service functions and reflash the multiple modules without fear of the battery running out of power and potentially bricking one of the motorcycle’s modules. This Optimate Select 7 does the trick! With my Hex GS-911 I was able to reflash multiple modules on my K1600, customizing certain functions, and ran the ABS bleed service function and never had a low battery warning (like I usually do).
