Yes, it will take slightly longer to charge, but it will last a bit more once charged.

A Rechargeable Lithium Polymer 900mAh battery
The 900mAh battery will work fine - it just gives your phone an extended time between charges. I've replaced the original 700mAh battery in my phone for a 950mAh one - and get about 40% extra talk & standby times.
Yes , you can use the 900mah. The 900 will hold a charge a little longer than the 820.
The charger with the 900ma output will charge the battery faster than the charger with a 500ma output. The phone with the 900mah battery will last longer between charges than that of the 500mah battery.
A 900mAh 7.4v Li-Polymer battery should be charged at a rate of around 1C, which means 900mA or 0.9A. Charging at a higher rate can decrease the battery's lifespan and safety. Always follow the manufacturer's recommendations for charging rates.
Yes, you can substitute a 900mAh battery for a 700mAh battery, as the higher capacity battery will typically provide longer usage time. However, ensure that the voltage and physical dimensions are compatible with your device. Additionally, using a battery with a higher capacity may affect charging times and overall performance, so it's essential to verify that your device can handle the increased capacity safely.

No the battery is built in but should last a long time.
the battery on your meter has to be replaced.
It depends on how much current is being drawn. If your device draws 1 milli-amp of energy, it will run for 900 hours. If your device draws 450 milliamps (mA) of energy it will run for 2 hours.
The current relates to the flow of electric charge in an object. Basically the Ampere hour is a measure of how 'long' it will last for. So a higher amount will result in a longer lasting battery because it 'contains' more current.
