What is the discharge time used to calculate the amp hours? The Amp-Hr. rating has little significance unless qualified by the # of discharge hours.

Your question is not about the item in question. I purchased the replacement batteries not the unit from Amazon. To find your answer I would go right to APC to get the particular specs that you want. The battery replacements had the same specs as the ones I replaced. My unit runs at 86 watts, which give me a 58 minute window to close down my system. I hope this helps.

you need to give the AH rating of your 12v battery to determine charge time.

Probably the Amps specs is my guess, i think one is 1.2Ah and the other is 1.5Ah

My husband uses them and they are as good as the ones he recieved from the specialist. They are charged each night and last 8 months or so. I do not know the amp per hour rating

The Reserve Capacity of this battery is approximately 40 minutes...Reserve Capacity and Amp Hours are NOT the same. A lot of people and even businesses confuse the two.RESERVE CAPACITY (RC) is the number of Minutes a fully charged battery at 80° F will deliver 25 amps until the battery drops below 10.5 volts. AMP HOURS (AH) is the number Hours a battery will deliver a steady 1 amp until the battery drops below 10.5 volts.Generally, if you double the LISTED amp hour rating, you would get a close approximation of the reserve capacity...Oddly enough, if you halve the LISTED Reserve capacity to approximate the amp hours, it can be off by as much as 8 points.

There should be a UL label on the bottom of the machine which states its watts and/or amps. UL is a third party evaluation group that gives accurate information. Could someone who has one of these machines tell us what it says?

i use this instrument in my auto repair shop. i find the volt/ohm/ampere function very useful. i don't know what you mean by time frame but you can measure AC voltage and it shows freq and duty cycle. I can also look at the Oxygen sensor output signal thru the OBD connection. i hope this answers your question.

AmpHours (Ah) is a measure of energy. Since this is solar, it has unlimited energy potential, but it can only provide it 15 watts at a time (watts is power and energy is power over time).But I wouldn't expect the full output... that's optimum or about .8 amps.If you could get that much, though, you'd have 8 Ah of energy after 10 hours.

It depends on the manufacturer and the drain conditions. You can look up the capacity (in milliamp-hours), higher numbers are longer life. The rated capacity will generally decrease with higher discharge rates as well.

I did a discharge test and it went for ~ 4 hours before the light intensity started to drop. After 5 hours the intensity dropped faster but even after 7.5 hours it was still putting out useable light. I'd post a photo of the discharge plot but I can't see how to do it for this product.

That is a confusing question. Batteries are not rated in amps. They are sized to a specific category of power output and then you purchase the battery to replace an existing battery of the same power output. The power rating is amphour. The amp hour of this battery is 2.6 amphours. It is sized to the drill and will deliver a consistent 2 amps per hour until the battery needs to be recharged. In this case the battery will run for 1 full hour at full load before a recharge is needed.

Very good question. I have not done a complete discharge test on the unit. However, to give some idea, I ran a new unit right out of the box for about 20 minutes. It was still working. I then charged the unit at the rate of one squeeze per second for 60 seconds and then ran the unit for 30 minutes. It was still producing light. I hope this helps.

Amp hours at 100mA Discharge rate=310mAH,at 500mA=170mAH,at 1000mA discharge rate=90mAH.Hope this helps you. 100mA=.1 amp

I think that I read somewhere that the time which it has on "stand alone" internal battery was about 50 minutes, although I am not sure about that ... I can't find it right now. As far as amperage draw is concerned, I don't have a clue.

mAh (milli-ampere hour) is a capacity rating that measures how much current a battery will discharge over a specified period of time. In plain english, it is a rough measure of how long your device will operate before it needs to recharge. In this case, it means the vacuum will cover more floor (or maybe the entire space) between recharging stops.

I wouldn't think it matters at all. I have never seen this low a rating- are you sure it isn't 3 amp or 2.5amp ? either way is shouldn't matter- there is probably a fuse to insure no overload. BTW- the one I bought seemed to work for 30 seconds and next thing it wasn't supplying any power at all. I never returned it , just used the old one that wasn't really bad. My alarm system needed a new battery and a fuse.

Its hard to give an estimate without knowing what the current or draw is from those devices. By looking at the Power details on the power supplies should give you all the info needed to calculate the duration.
