Yes, there should not be any problem.
probably not. get the right battery.
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.
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.
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.
No - so long as it's the correct voltage it'll be fine. The mAh figure is the battery's capacity - the higher the number - the longer it will last between charges in the same piece of equipment. It'll take a bit longer to charge though. I have a mobile phone - which came with a 600mAh battery. I bought a 950mAh equivalent off the 'net and get about twice the talk-time from it. I charge mine through my computers USB port when I need to.
the battery
A battery that can be refilled with the energy it has. If it is in a phone, when you charge your phone, you are recharging the battery in your phone.
A VTech battery is a battery that is used for your VTech wireless phone; the battery is basically going to power your phone, and allow you to continue to use the phone when it is not on the base.
Your phone has a battery behind back cover as a power source.
A phone battery can be put into the freezer when overheated. After allowing the phone battery to cool down, remove it from the freezer let it come to room temperature, and place the battery back in the phone. Yes it will work.
If your cell phone will not charge it could be the battery or the battery charger. You best way to find out is to try the battery charger on a similar phone and see if it charges the other one.
When the phone is turned off, the battery provides a trickle of power to maintain the memory in the phone.
