Nope....more so a group of guys taking the time to point out what has and has not worked for them.....hoping to save someone some time/effort....that's all, nothing more.
If all you want is a tender, the cheaper battery Tender Jr (.75A) is fine, but 5 year warranty instead of 10 year. I got the Plus (1.25A) because I wanted a bit more power for an Odyssey AGM battery in my truck that runs an ARB Fridge Freezer and therefore gets run down more from that extra load.
Neither are good for recharging dead batteries, but both are good maintainers.
