Quite pricey.
Yes, much too low for flooded or AGM. I bought a used Battery Minder wall wart charger from a garage sale a few years ago that was doing the same....I threw it in the trash.
I'm sure it will work, any properly operating battery tender will "work" on an Odyssey. I used a standard NAPA 1.5amp battery tender on one many years ago without issue. But if you want to maximize the life, I would use an approved battery tender on their list. You are spending $300+ for an Odyssey battery, why would you not invest a bit on the battery tender to ensure long life?
Thanks for the info.
Ive been using non agm optimate 6 5 amp chargers for about a decade now on all my odysseys - oldest one is now at 15 years old.
Warning on the $25 wall wart 1 amp Battery Minder sold by Northern Tools. It seems to float at a lower voltage than my larger, more expensive battery minders. It supposedly has temperature compensation and has the same thermo probe as them. but floats in my cold garage (upper 30s) at around 13.5 where my others will float at 13.7 to 13.8. Also during a 24 hour cycle, I do not see much voltage change from temperature compensation. The 1 amp Battery Minder may adjust by only .06vt where I can see up to .15 or more change during the same temperature range. In other words the 1 amp Battery Minder seems to float at a lower, less than ideal voltage and the temperature compensation does have as much effect on voltage.
Odyssey also wants the float voltage temperature compensated at a specific rate. Higher when colder, and lower when hotter ambient temperatures. The 13.6vt is specifically at 77F.
Id be interested to know how many people who have odysseys have turned their key and never thought twice about a charger. I know until recently, I was that guy. Now I’m willing to chart and log and spend to make a $100 battery last 8 yrs. Heck, I’ve always gotten 4 yrs out of my batteries and maybe charged them once or twice. Now if my cars are at home, they’re getting charged with 1 of 8 different set ups. I’m nearing retirement and almost an empty nester.
My local pawn shop has a 2012 new in a box for $35 (not agm). Any issues using this on an agm that isn’t odyssey or optima? Seems like a good deal. It also comes with a 12 ft extension cable.
The Battery Minder 2012 is fine for regular AGM batteries. The 2012 AGM is for Odyssey and Optima specifically.
It’s in plastic packaging. I grabbed it, because why not at that price. I looked up the price of the charger and the cord and this was a screaming good deal.
Your expectations are misdirected. Speed is not a function of performance. The 2012 is a 2 amp charger, the Northern Tool version is 1amp. Of course they will take longer. Two to four times longer than the 4 amp Pulse Tech. If you want a faster charge, get a higher output maintainer. But understand every battery manufacturer will tell you that "low and slow" is always better for battery longevity. Speed may make you feel better...but what is your hurry? These are "maintainers" primarily, not chargers.
