How long at max draw (125 amps an hour) does it take for this battery to rundown to the 50% level with no charge input

Amp hours are a measure of power. Theoretically, the battery should provide 125 amps for one hour at the stated 12 volts. However, at this high a current, I wouldn't count on it. More realistically, the battery should provide 10 amps at 12 volts for 12.5 hours or 20 amps for 6.25 hours...and so on and so forth. My experience is limited because I use them (two of them) along with an inverter to run a refrigerator and a few other pieces of equipment in a back up mode. They have done great when I've needed them!

It would take an empty to 20% in about an hour, to get full charge would take longer. I have not try that yet.

It takes sometimes up to three short charge sessions to get a new battery up to snuff. Watch the temp of the battery case and if it gets warm-hot stop charging it and let it sit for a while. It needs to sit for at least an hour after you pour in the acid, tip the battery slightly to get all the bubbles out. Don't press down the battery seal (caps) until you get the battery to accept the initial charge(s). Then you should be good to go. Don't exceed 1 1/2 amps.

I am running a 100 watt rms amp drawing about 10 amps for 9 hours straight and the battery was still going strong. Hope this helps.

Probably an hour for a full charge. I finally had to replace my battery because it would not hold a charge. Pull yours out and see if it is bulged in the middle. If so it is bad.

Typical charge time from fully drained is about 3 hours. If it doesn't clear during that time, the battery is bad. I ordered 2 of these, both had old manufacturing dates, so they are most likely used and were pulled from recycled units. I powered down both servers (2x 2950), installed both batteries, powered up the servers and the ROMB errors were instantly cleared.

4 AA 2500mAh batteries in 5 hours so 4 x2000 in 4 hours or 500 ma per hour. Won't make any difference what your charging source is, it only draws 500 ma

Mine was nearly fully charged when I received it. I have not run the battery completely dead during any single use yet, so I can't be certain. I would guess it should fully charge within an hour.

2 hours max. After using one battery until the camera turned off, I took it home and charged it to max capacity and it was a little under 2 hours. You may want to contact the seller. If it is the same seller I used, they are excellent and will replace the dead cell. But first use a different outlet to see if you are getting 100% from your outlet. Just a suggestion.

No, that's ridiculous. I ran mine last weekend for a solid seven hours, with intermittent bursts on full power to get from one point to another. I also run my fish finder off the same battery. When I got home the battery was still 80 percent charged, and that's the most I've ever drawn it down.

Not sure. But what I do is run it till one bar of life is left on the indicator and take a break while it charges or plug it in for a charge while I use it. But to be clear I would say at the very max maybe 30-40 min

depends on how discharged your battery is . most of my batteries were charged within 24 hours are less. sounds like you have a battery with a weak cell that will not let the battery come to a full charge '

Depends how many AH is the battery. For every AH you need 1 amp so for a 100AH battery theoretically you need 20 hours at 5 amp to fill it up. However that its not always the case. You only put out 5 amps at full blast and not at lower voltages.

Yes. 6800mAh is 6.8 Ampere-hours at 12V. It should therefore be able to run at 1.5 amperes for more than four hours. I wouldn't run it much higher than that, though. 1.5 Amps is a lot of current for that little battery. I routinely run a 3800mAh unit (=3.8 Ampere-hour) at 0.9 Amp for over four hours.

Hi, Dakota. Each battery assembly half is rated at 9 amp hours so the unit is a total of 18 amp hours. I think the warranty is two years. I have had mine in service for over a year and a half and it still charges up to full original capacity.

From 0 -100% on the trickle charge it would take about 35 hours. On the 12 amp setting probably 16 hours.

The battery has run 3 hours with no problem. Probably will go longer with a full charge. I stopped before the battery did. This is an excellent tool.
