If these batteries really are 2300 ma/hr cells, why doesn't it say anything at all on the package or the battery about the amp/hour capacity?

In the batteries, under + and size AA you can read 2300 mAh. It's true ??? I don't know exactly

You would have to check with B&D.; I looked on the battery and the box it came in and could not find anywhere what the mah rating is (which is kinda strange). I can report that they do last a long time.

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

You can't tell if they are a good deal or not unless you understand the capacity of the battery (usually measured in milliamp hours. AKA Mah). Unfortunatly, Amazon doesn't understand this because most of the specs don't list this peramiter.

Colleen T. The replacement battery pictured says it has 1150mah, I bought 2 in Oct. 2013 so far I have seen no differencein the charge life. I would think only a Lab controlled load test could detect any difference. Except in price.

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.

Hi. Sometimes they are labeled as Ah (amperes/hour) and sometimes mAh (milliampere-hour) it depends on the manufacturer maybe to be more accurate. please refer to http://en.wikipedia.org/wiki/Ampere-hour

I believe they are. From what I have observed amps are not usually written on batteries. They are identified by voltage. The manufacture can give additional information about the product. That's what I believe is happening here. In terms of performance they are great.

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.

I don't have an answer to your question, but these batteries don't hold a charge at all.

No idea! I have used these as a cost effective alternative to the Duracell batteries. I find they perform the same as a Duracell with the price drop related to no marketing cost.

They are not well marked, but the very best : 2800 or 2600 per battery. I gave them as a Gift , so I can't pull one to tell you for sure. But I do know that they are THE best !

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

The printing on the batteries themselves says "2400 mAh". I ran them through a full test on a LaCrosse battery charger I have (full charge, then full discharge, then full recharge to count the capacity) and it said 2500 mAh. So I think at least with the ones I have, I can assume the 2400 mAh printed on the batteries themselves is accurate. I also submitted a request for them to change the "product details" to reflect what's printed on the batteries.

it actually is 23000 mah...I used it for my laptop and extended the battery life by a few hours.
