That depends on the amount of power being drained from it.
No reason why not. So long as the physical size of the battery matches, and the voltage it delivers is the same - you should be able to replace it with the higher mAh battery.
1 hour max
What's up out there? My question is how much time will a 2160 mah battery give me on my camcorder?
12 hours maximum
With a charger specifically designed to charge this battery.
If you divide the 5000 mAh by the current used (in mA), you will get the number of hours the battery will last.
1 hours
It lasts 8hours
About 11 minutes
Yes as long as both the 2450 mAh battery and 600 mAh battery have the same voltage. The larger one will just last longer and take longer to charge up (I am assuming these are the solar powered type lights).
The battery with the larger mAh rating will last longer that the battery with the smaller mAh number will last in the same application.
Yes you can. I answered a similar question to this a few weeks ago. The mAh figure is simply the capacity of the battery. So long as it's the correct dimensions and voltage - it will be fine. I have a Sony Ericsson mobile - which had a 600 mAh battery in it. I replaced it with a 950 mAh battery - which has extended the time between charges.
