Has anyone tested the capacity of these batteries to see if they really are 1000 mAh?

How would I go about conducting such a test? I don't think it would be worth the time and/or effort to do it.I also have a pair of these batteries by Philips, and a pair of Rayovacs, and two devices that use them, and I don't find any noticeable difference in performance.

The ones I received were 800 mAh, clearly marked on the card. This is a picture of old packaging. Not sure if Duracell still produces the 1000 mAh version. Watch out for expiration dates...........

I have not measured them, but after a full re-charge, they last me through a day of home inspections.

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.

They are 1200 mah. These were a good buy and they work as well as the Nikon battery.

Maybe, but these batteries are falsely labely and have varying outputs, nothing like what is stated. Plus these batteries are not protected and can possibly burst. I should warn you that the charges can catch fire easily too. These are imitation batteries. They should be around 10$ for 1 quality battery.

Its possible because I have each one of 4,000; 5,000 mAh. They work great for me.

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.

You can not say the battery is 2000mAh and then in the description state it is only 1500mAh. In this case you must assume that it is not a 2000mAh battery, but instead only 1500mAh. Very poor advertising and buyer beware.......if you only read the title you may assume you are ordering a higher capacity battery than is described in the detailed description. Maybe it is a mistake on the part of the seller (giving them the benefit of the doubt), but either way I would call them and ask them what you are really getting.

A reviewer on the trustfire 26650 batteries said that the ultrafires that claim 6000 mAH are more like ~3200 mAH. ymmv, but I've never seen any of the 'fire' branded batteries actually reach the claimed capacity.

Depends on your charger, and how much capacity the batteries actually have (most Ultrafire batteries have false mAh markings). I wouldn't buy these, all except for one I've ever heard of were bad batteries, and even that purchaser found the capacity was 2000 some mAh. I'd find some Panasonic 3100 or 3400mAh protected batteries instead, these Ultrafires are not worth it.

These are fakes. There is no such thing as a 4000 mAh 18650 battery. The company is fake, too. It spams five-star reviews for its own products. You can tell by looking at their "other reviews".

I checked the batteries and the branded box they came in. There is no mah rating; only the voltage. Perhaps Duracell doesn't want you to know.

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.

I purchased 10 of these batteries to make an eBike battery pack. I tore them apart and tested every individual cell with an Imax B6 charger. Cells are about 2000 mAh, which makes the whole pack 6000 mAh. They seem to be good quality since they are not too far from the specs which is 2200 mAh per cell. Also keep in mind that the capacity gets lower as batteries wear out.

Amazon doesn't specify the capacity in mAH. Judging by the part no. they seem to be rebranded Sanyo eneloops which are rated at 2000mAH:http://www.cnet.com/products/sanyo-eneloop-hr-3utg-4bp-battery-aa-nimh-x-4-series/specs/ You can always return them if they are much less.

Perhaps you should look deeper and see if both batteries are of the same capacity? Milli Amp capacity? Run both numbers that you have through Amazon, or LG which ever website is more capable (or both) and see if one battery is smaller capacity than the other. As I remember, this battery is either 1000 or 1100 milli amp capacity. all of the batteries are 3.7 volt Lithium type. Happy research. dot

A voltage meter won't tell you whether the batteries meet manufacturer specs and supply full power under load. You need a battery tester like the ZTS to do that. I just received an order of Duracells that failed that test - the second such order of CR 123 batteries from Amazon that did so. The first order was Energizer brand. I learned of the deficiency the hard way when my security system started sending off false alarms after I installed the batteries. I talked to a battery shop specialist, who said that happens when they resell factory rejects.

They are only 1.2V (all the 1.5V I found are alkaline batteries).For your purpose, I recommend you get the 1.2V rechargeable with the highest mAh. Personally, I would get these:8 pcs of Tenergy C Size 5000mAh High Capacity High Rate NiMH Rechargeable Batteries
