The GMC-320 has longer working time after charged battery. It is about three times longer than GMC-300.

If you were to restate 3000mah (milli-amp-hours) to just 'ah' you would see it stated as '3.0ah'... So the 3000mah battery provides more power than the 2600mah battery. Essentailly, the 3.0ah battery will provide it's power for a longer period of time than the 2.6ah battery. So your Drill Driver, etc., will keep it's strenghth a little longer 3.0 vs the 2.6... Hope that explains it.

I tend to keep mine on power save, it seems to last pretty well. I'm not sure and exact answer on a number but several hours.

Charging time will depend on several factors... how sunny it is, how much capacity (rated in Amp Hours) your battery has, etc. The R15-300 produces 0.3A (at 15V) to charge a 12V battery. For example... If your battery capacity is 10AHr (amp-hours) and it's down to 70% full, that means you need to add 3 AHr back in... As this panel produces 0.3A, that means in 10 hours of full sunlight (max sun) you will restore the depleted 3Ahr. Of course, the sun intensity isn't always at max strength, so it would actually take longer than that. If you need to recharge faster, then a larger panel will be needed. I hope this helps explain it.

I have a 3200 not a 3100, however suspect the same as far as battery goes? I seem to remember I had to use the genuine Nikon battery as one of the two to get it started. From then on it has worked with non genuine batteries in both spots. I did read once that the bios upgrade for the camera would prevent any aftermarket batteries from working, si I haven't upgraded mine. I love mine and esp. the shutter release on the grip for when holding camera in vertical or portrait position.

Robert,I believe I have both and have notice no difference between the two. I don't let them run down and keep them on a regular charging cycle.

I am not certain on the 300's size however it will hold my Charge with bit kit and a redi edge sharpener.

helllo, not sure of all the differences, but I noted that 840638 charges in 3-5 hours, while 840045 charges in around 8-10 hours. That is on the product description section of each battery. Hope it helps!

I ordered two. They work perfectly. The higher 2400ma means they have more capacity - last longer. However, be careful when ordering. There are two different models with the same part number. Insure that the contacts in the picture looks exactly like the contacts on your current battery.

I have the 100 and the 300 and the charger looks the same to me. But there could be a difference between them. Sorry I can't give you a better answer.

3100 mAh is the capacity of the battery not the output. So no it shouldn't hurt it, just make it last longer.

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.

Yes the 20 watt is faster. And you can put them both to the single 12 volt battery as long as they both go through the overcharge protector(s).

I have the Elph 320 which came with the 3.6v battery and the 3.7v that you're asking about. They both work just fine in my camera so I would expect the 3.7v will work just fine in yours.

I've had both electric & battery. Neither is more powerful than the other. How can anything be powerful when it runs off of 3 volts maximum? The battery units (AA or rechargeable) are more convenient because you can use them anywhere. I prefer to use it outdoors, weather permitting. The description says "spins at UP TO 47 rps", but I can't tell any difference between "UP TO" 47 and a real 30 rps.

I haven't noted any difference between the two modes of operation. Unit works well and typically runs 10 - 12 hours per charge.
