How many watt hours is the battery?

The battery is a 6fm-18, listed on the battery as a 12v-18ah/20HR. I'm not sure of the formula to convert the amp hours to watt hours.

runs by cord or 4 AA battries. Not sure the wattage but the batteries only last one or two times

It would be safe to say 8 hours, but it lasts a long time. There is no worry in the battery department!

The battery we received is a 40v Lithium G-max, 146 Wh battery. I'm not sure how this crosses over to the amp hour rating. If they assume you have a constant 40v for the whole charge, that would be 3.65amp hours. If they take into consideration the voltage degradation over time or that it would not be used at a constant 40v output, they may estimate it at 4 amp hours. The battery model is #29472.

I have not measured the battery but I have had mine in use for over 4 hours hope this helps

I'm not sure, because we use it as a battery backup to our server. The times I've needed it, we've gotten at least 2-3 hours of backup for our server before our electricity came back on.

The battery accurate capacity is 300 Watt-hour. However, most external batteries on market use battery cells mAh adding up to give total mAh capacity. 83000 mAh is just for comparing with those external batteries on market and this 83000mAh is based on battery cell nominal voltage, which is 3.6V ~ 3.7V. 3.6V x 83000mAh = 298.8 Wh, 3.7V x 83000mAh = 307Wh. We suggest using "Watt-hour" instead of "Amp-hour" or "mAh" to compare capacities of different batteries. Watt-hour or Wh, is a more accurate unit to show the power capacity than Amp-. Hour (Ah) that was used before. The Watt-Hour unit means the wattage that the battery can provide within one hour. If you see a battery just marked mAh but not Watt-hour, you may use mAh x 3.6 /1000 to figure out its watt-hour. Best regards.

The run time depends on the amount of watts being used and the amount of wattage being put into your battery.

24 watt hour sounds like 1.5 amp hour. more information can be found here http://toolguyd.com/ryobi-18v-lithium-ion-batteries/

Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose. Rule of thumb batteries should not be drained more then 50% or maximum 80% otherwise battery life will be compromised, so we will consider 600 watts to be charged. 600 watts divide by 144 watts = 4.16 hours. Since this panel is 24 volt and your battery is 12v - MPPT charge controller is highly recommended. MPPT charge controller can accept higher voltage (24~36 volt) from the solar panel and charges a lower voltage battery (such as 12v). Morningstar SS-MPPT-15L will be a good charge controller for this setup. Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose.

I don't have exact time but I have used mine several hours now and still using original batteries.

It would completely depend on what you are running I have not ran it down yet but you never really want to run a battery with high amp draw down under 40% with. I would guess a dc refg 3 days. You take the total amp hours times 12 gives you the watt hours on the battery. I haven't done it yet.

amazingly the wattage is not specified. we haven't used it for several years on one (1) occasion, but as best as we remember it shuts off after 2-3 hours.

I hope this helps??? *Power: 10 Watts, 75 Lumens - 7.4 Volt / CE Approved *4400 mAh Rechargeable Lithium-ion Battery *Working Time: 3-4 Hours *Charging Time: 4-5 Hours Do not over charge it will reduce the battery life OK

If you have a battery with the capacity of 120 ampere-hours and you draw 10 amperes continuously, the battery will last for 12 hours. Divide the capacity in ampere-hours by the continuous-amperes being used and you will get the length of time that the battery will last-that is if you do not charge it. The question of 4000 watts does not enter into this equation. However the theoretical amperes that this 4000 unit will put out will be-- 4000 watts divided by 120 volts equals 33.3 amperes. I suggest that, from your car, you do not draw 33 amperes at 120 volts however.

Well, my computer is using 300 watts right now and the UPS says it can run for 20 minutes on battery. If the conversion holds up, that'd be about 100 hours.
