What does 440mA Mean? Can I charge a 10,000 D Mah battery?

440 mA is the milliamp charging the unit does. So your D cell will hold 10,000 mA for long life. So yes, your D cell will charge to 10,000 at the 440 pace. Might take a few hours.

Question 1: It's the charging rate of the battery. "maH" means milli-Amp per hour. A "milli-Amp" is 1000th of an Ampere. Q2: Yes. I have charged 4-10,000 maH batteries together on this unit. And, so far, so good. I buy very few alkaline batteries any more. If space permits, or isn't an issue, I always carry a charger when travelling.

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

I believe the 4400 means that the charge will last longer on the battery you received versus the one you had. So, yes, it should totally work.

The 6000 can store 6000 mah of power and charges at 1.2A and 2.1A. The 3000 can store 3000mah of power and charges at 0.5A and 1.2A.

Not sure. Its 10000 mAh though. My 2900 mAh battery in my phone takes an hour or two. Just charge it over night. I've never had an issue. It's basically 3 and a half phome battery's so it will tale a little while for a full charge.

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!

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.

The 4400mAh has fewer battery cells than a 7800mAh. The designation mAH is how much energy the battery holds (when new). So the 7800 will power the laptap longer. Physically the 7800 is larger to accommodate the additional cells. The orginal Dell battery is the 4400 size. If you go with the 7800 battery the battery pack will stick out beyond the back of the PC about a half inch.

Going from 900 to 2000 will more than double your time using the battery. The mAh rating is the capacity of the battery, or put simply how long it will last.

The writing on the battery does not indicate the number of cells in the battery. It states DC 11.1V, 48 Wh(400mAh)
2096916
These numbers are rating the capacity of the battery. As long as the voltage is the same there will be no damage to you device. The difference in capacity is like have a bigger gas tank it just means that the 1000mAh battery will last longer i.e take more pictures than a 700mAh battery.

my old battery has 10.8v, 4.7wh and 5200ma on it. I ordered by the HP part number and received a 'replacement' that has 10.8v and 5200mAH on it.

as long as the battery fits your model, you should be good upgrade. all you are getting is a larger battery storage, but the battery will still fit your model. no need to stay at 4400

This one is has a 2000mAh battery ....not a 4000mAh battery. For reference, a rechargeable "AA" battery is 2500mAh. mAh is milli-amps per hour. This unit has an attached micro B power cord but also has a USB port to plug your power cord into. Here's another unit to consider http://www.amazon.com/gp/product/B00JM59JPG/ref=olp_product_details?ie=UTF8&me= this one has 2 USB ports and is 10000mAh but is fairly thick. Both power packs are capable of running 2 devices at once.

Mine says 600mA but it send to charge faster than that. I've had mine for probably a year with no problems.

Shouldn't be a problem as long as the physical size and voltage are the same. Higher mAh means higher battery capacity, and longer service between charges.
