Yes, but it is not advisable if you live in a very cold climate.
probably not. get the right battery.
Yes.
Not a good idea. It will work but not as long as the 1000 mAh battery.
1000 Milli Amp Hours How long the battery will last.
No problem to use the 1100mAh in place of the 1000mAh battery. Mah is like store rooms that have varying sizes. As long as the voltage remains the same (the doors of the store rooms are of the same width and height), the battery with a higher mAh can be used.
It means it has more power.If it fits in your phone it should work.But look where the battery goes it might say there is a may battery you can put in it.
Depends on the battery's mAh rating and what the charger's mA rating is. Say the battery is a 1000mAh Lipo battery and the charger puts out 500mA, the battery will charge in 2hours.
1000 mAh is the capacity of the battery. A single rechargeable cell would give 1.5 volts, regardless of its capacity.
Yes, there should not be any problem.
Voltage-wise the apparatus will not be damaged, only that the 800mAh will provide longer run time than the 550mAh
If, by 'larger battery' you mean one with the samevoltage but higher capacity - there's no reason why not. It will simply take a little longer to charge it. I swapped my 3.6v 600mAh battery for a 3.6v 1000mAh battery a long time ago - and the phone still works perfectly well.
I have designed many charging circuits and generally we try to keep the max recharging rate of around 10% of the battery's discharge rating. For your Nickel-Metal-Hydride (Ni-Mh) battery that would be a maximum of 80 to 100 Ma.
