can use 1400mah battery to replace 760 mah
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.
Sure, if they have the same voltage.
Yes, a 750mAh (milliampere-hour) battery has a higher capacity than a 500mAh battery. This means that the 750mAh battery can provide power for a longer duration or supply more current before needing to be recharged. In general, higher mAh ratings indicate a greater ability to store and deliver energy.
It needs a small connector and comes with a 8.4v 1400 mAh battery.
the answer is c : 1400 mAH
it is the Acronym for Milliamp hours No, not an acronym. It's just an abbreviation, which should be written mAh. A small battery's capacity is given in mAh, and is the approximate product of current and time. e.g. 500mAh means it can deliver approximately 500mA for 1 hour, or 50 mA for 10 hours etc, pro rata. Larger batteries have their capacity stated in Ah.
If the voltage is the same, with suitable connectors, and it fits in the space, probably yes.
Yes and no. The higher capacity battery will last longer, but you need to consider the charger. It depends on the design of the circuit.
mAh stands for milli ampere hour and it is a measurement of how many milli amps of current a battery is capable of producing in one hour. Yes you can substitute a battery with a higher mAh current rating provided you use the same battery voltage.
Not a good idea. It will work but not as long as the 1000 mAh battery.
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).
