I finished plotting and annotating some
Battery Tender Jr. performance compared
to a laboratory-grade charging profile
with a bench power supply.
I hope the plots are self explanatory:

It's interesting that in spite of the fact
that the BTJr wall-wart does not feature
an oft recommended 'top-off' feature, the
energy pumped into our test article battery
was not substantially different than application
of the 'lab-grade' recharging profile.
I've got a couple BTJr C-Ms shepherding
100AH truck batteries out in the shop. They've
been on maintenance for over a year. Just
for grins, I'll go measure the maintenance
current on them tomorrow.

Not that particular series . . . here's a family of
