1432 mah battery
None, battery capacity is specified in mAh not mA. The capacity of an AA battery varies from 1700 mAh to 3000 mAh depending on the battery chemistry (e.g. carbon-zinc, alkaline, lithium).
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.
You simply divide the MAH of your battery the MAH of your charger. For example my battery is 1500 MAH and my charger is 250 MAH. 1500/250=6 which means I have to charge my battery for six hours.
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.
mAh = milliamp hours, which is battery capacity
That would depend on the actual battery's specifications. I've seen some D cells rated as low as ~2000 mAh. However a full true D cell should have a rating between 10,000 mAh and 15,000 mAh.
The high capacity psp battery usually include 2400 mAh, 3600 mAh, also 3800 mAh,
1.5 Amperes, or Amps.
1.4 million mAh
The mAh for a battery is the rating to express the available current at the rate voltage for one hour.
