Likely another 4+ hours after that to get to true 100% Full.
Need an ammeter to check.
I've got a SnapOn battery tester I'll throw on it tonight. The charge controller gives me pause.
This morning (in the dark before work-everything still hooked up) I was getting 80% capacity reading at 12.4v indicated. That seems to jive with the charts I've Googled. It does not have any programming available - for what I paid I'm sure it's just enough to keep from overcharging and depleting at night.
Yesterday a simple cigarette lighter plug in meter was within 0.10 volts of the controllers reading.
I'm assuming a semi-accurate "capacity" reading comes from the battery "resting" and equalizing after a charge session? I really wish I knew terminology better, lol.
FYI - the battery is brand new - went into service March of this year with a manufacture date of February 2018.
We rarely run the battery down hardly at all - maybe charge the phone, some led reading lights, and last time judicious use of bed warmers - it's just nice to have the capability and I'm a geek tinkerer...
