Woo Hoo..New AGM Batteries

two of the new ones in their workplace, the battery rack

last night 7:30pm meter 12.93v lights and fans running
this morning 6:30 am (early for us) 12.62v down 65ampHrs from full

i set the capacity at 500amphrs although technically it would be 540 at the 20hr ? rate
8hr rate would be 480amphrs total to discharge

anyway it like 2011 all over again, now i can go days if need be instead of just overnight

Where did you get these? Also I wonder which ones of their battery's would be equal to Interstate U2200 6V deep cycle battery's

100% SOC = 5 amps @ 14.4 volts?

was down 97amphrs over night
meter SOC approx 85 percent
capacity set at 600ampHrs, 5 AGM batteries technically 675 AmpHrs total capacity

Y'All need a dose of that West Vir Ginny weather.

Las Peñas, slopping green vegetation doesn't burn.

Vizcaino peninsula, salt and sand don't burn.

I had to toss off the Thinsulate comforter last night. Fleece blanket tonight. Also shutting the cellular off - ****...

Oh Yes Please
that would really help the fire fighters

Would you like cool 60F with rain from Pacific North West?

PT send some that cool air down here,
we are in desperate need of it
it would help the fire fighters immensely
I could also use some of your 16hr sunshine, be good for my solar and batteries

With 270 bank starting with 80% - 4 hours before float - with combined efforts of 30A solar and 60A generator charger - sounds like normal time. Mere 60AH to top up. Shouldn't take much longer without PD70 input either.

I see a similar picture on my low-end 300 AH AGM, with 30A solar alone. No generator charging (since no A/C). Though mine start with 85-86%, entering 14.6V stage after 3 hours. 14.6 stage lasts 1 or 2 hours, then 13.6 stage is triggered by low accepted current.

I hear all the time about "waking AGM up with high current". Didn't notice them ever wanting more than 20A before 14.6V and not sure if I should be worried about this, given 85% start. Waken up or not, they are full in early afternoon, stop taking charge shortly after they've entered 13.6. Very high self-discharge though. Crappy Chinese jars.

if NO A/C is needed, i can get 6~7 hours from a 1.6 gal tank

That would be zero gallons in my case - no generator when no A/C is needed ;)... OK, no fuel discussion, sorry Mr Wiz...

I understand exactly why Mr. Wizard is happy. Been 10 months with my DEKA 145 Telecom AGM... and if at 60 to 70% SOC, on the EU2000i and the 30 amp MegaWatt, that 150AH Telecom surplus AGM might take 21 amps at a 14.4V setting on the MegaWatt 30. Discharge it slow, and charge it slow. No matter what, stuffing it with a couple of hours of Mega Watt every few days is what the battery likes, otherwise, it's just the 150W solar panel at 8.5 to 9 amps daily.

This battery needs to be pushed by the MegaWatt and pedestal, or generator, every 4 to 6 days, at the 20 amps plus, to really wake it up from time to time.
