If this is a 9 Amp Hour battery, why does the AMZN description say it is a 7.2 Amp Hour battery?

I really can't tell you why the description says 7.2 in one location and 9.0 in the detailed description. It could be a typo. All I can tell you is the battery works great.

440 mAH (milli amp hour) battery is 6 cell and 780 mAH is 9 cell. mAH is the capacity of the battery, like how many hours you can run the computer on the battery alone.

That is the battery life. If your device draws 1.4 amps the battery will last one hour.

Ken J was real close. You have to take 80% of the atv battery's AH rating (which, by the way, can be anywhere from 4 AH to 36 AH). You never discharge a lead acid battery 100% (12.0 volts open circuit is discharged, 12.72 and up open circuit is fully charged). They have a very high resistance to recharge when you discharge them completely. So a 5 AH battery has 4 AH available. Drawing 3 amps for one hour is 3 AH. So that battery would only last about an hour and 20 minutes give or take a few. A 36 AH could go over 9 hours. So it ultimately depends on what AH battery you use.

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

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.

The battery provides typically 10-12amps, when the battery is running you are provided 14.8amps. Likely, it doesn't have a fuse, or isn't built with the best quality and would draw too many amps thus destroying it

It could be labeled as 2AH. Smaller batteries such as these are traditionally labeled in mAh.

They are probably overrated, but 1000 mha is 1amp for 1 hour. that is how long the battery will provide 1 amp worth of energy. I would consider this rating useless as there is no energy draw stated for most electronics.

It is definitely not 7,5 hours. 3 to 4 hours, I would guess. I used it more than 3 hours yesterday, but I think that you will not get 4 on that battery, even if power management is set to reduce maximum. After a year, I expect 3.Right now it says 1:56 (46%) remaining. Indicating +4 hours totally.Cheers

The battery is B&D; LBXR36 40V max Type 2 54Wh Lithium-Ion. Amp hours are not stated. Possibly check on B&D; website.

Batteries are rated in mAh or milliAmpHours. AA batteries are normally 1500 mAh. This means you can draw 1500mA for an hour or 1.5 Amps for an hour (just removing the milli by multiplying by 1000).If you are drawing 2Amps this would last for 1.5Ah/2A this leaves you with 1.5/2 hours or .75 hours or 45 minutes.

This is a 12V battery, but for running even a small winch that still pulls ~40 amps I'd go for a bigger battery. This one is rated for 18 amp-hour (hinting it'll supply 18 amps for 1 hour, or 9 amps for 2 hours, etc) and I don't think it's a good idea to pull more than that 18 amp rating for more than a few seconds (like to crank a car).

I agree with Mr. Young.. mAh is just the capacity and has nothing to do with the actual output.. it's the 2.4v that's important. In theory, this battery should last a but longer than an 800mAh, but battery manufacturer specifications of their battery capacities are not always correct. At the price, these batteries are a great deal!

Hello Kristin, We can't speak for other sellers of this product, but if you purchase from Battery Supersite, we ship the higher capacity version of this battery which IS sealed (non-spillable) lead acid and 100% rechargeable. It has the same 12v output as the 12v 4.0ah, but is rated at a higher capacity. The capacity is listed as the "ah" rating, or amp hour rating. The amp hour rating is simply just the capacity of the battery and how much reserve power it can store. It's like the gas tank in a car; the larger the gas tank, the longer it can run. We always search the market for high quality batteries that will have a higher capacity but keep the output the same. The important thing to check is the voltage as the voltage should always be the same (ie. a 12v cannot be used where a 6 volt was used). A good example of this is the 4ah and 4.5ah battery. Nearly every battery manufacturer has updated this size battery to the 5 amp hour battery which will provide up to 20% longer runtime than the previous capacity battery. Feel free to contact us with any questions. Battery Supersite "The Amazon Battery Experts"

The part number show 7.5 amp hours. So, it should be. I haven't taken mine out and run it across an amp hour tester. No one has one.

I checked the specs on the Moultrie website and it says this is a 5 AMP battery, and when cross checked w similar batteries this appears to be the AMP HR rating. I hope this helps. Source: http://www.moultriefeeders.com/6-volt-rechargeable-safety-battery
