So if this needs to be merged or whatever feel free. Topic is observations on performance difference without conclusion (I am after the conclusion) between the Battery Tender (BT) branded Jr. and the Plus models. In history I have had a BT Jr. keeping watch on my non-Yuasa YTX-14-BS for a couple years. It was a pre-charged job that I dropped in and away I went. The OEM Yuasa was never really that strong and I suspect it was a shelf battery (or used) dropped in without full charge at time of sale by the ass-clown dealer (but thats another series of stories). Recently I needed to charge a pair of Yuasa NP7-12's. I decided to buy and additional BT and selected the "Plus" model, as I already had the JR. Here is where the observations come in. Both on the bike and on the NP7-12's the Plus takes a lot longer to go solid green than the Jr. For sure the output of the Plus is higher at bulk charge than the Jr., however why on earth the full-charge solid green takes longer I cannot explain. Does the Plus have an additional charging step that the Jr. does not have? Kinda curious and not sure exactly what is up. While it is nice to think the Plus doing a more thorough job than the Jr., I'm without experience reports of others to compare.. Your own experiences with these two would be interesting. I'm pretty sure I'm not the only dude that has both models in his garage.
