It takes 9 hours 10 minutes to fully charge. Sometimes the wait will be longer, sometimes shorter. If you just used a battery for a short time, than it won't last 9 hours to charge. If you used the battery fully than 9 hours is the time it will take to charge completely. Every battery is different, and some may take longer.
Any NiMh battery pack will last for a long time and won't lose its charge over time.
No set answer to that. It depends on charger output and battery capacity. Usually a few hours.

A set of NiMH AAA batteries can last roughly a month on a full charge if they are not being used at all and are simply allowed to sit around. In devices such as cameras and small pda's where rechargeable batteries are best used, the batteries can last nearly as long as normal alkaline batteries on a full charge. Exact times depend on the capacities of the NiMH batteries. A charge lasts long enough for a camera to be used normally for several days and hundreds of shots. As long as the NiMH batteries are not allowed to be idle and self-discharge, the life of a single charge is almost as long as a full alkaline battery. The life of the battery itself can easily be several years. NiMH batteries don't need much maintaining and can last for hundreds of charge cycles.
It typically takes around 1-3 hours to fully charge a 7.2V NiMH battery, depending on the capacity of the battery and the charging rate of the charger being used. It is important to follow the manufacturer's guidelines for charging to ensure optimal performance and safety.
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.
The battery life all depends on your driving. For example the Traxxas Rustler VXL's battery life will get about 20 minutes (Still depending on how hard it is driven). But don't think that 20mins is nothing, its actually pretty good for an electric r/c truck.
No set answer to that, it depends on the size/capacity of the battery and what it's powering.
I think you will find that this is not at all recommended. Different battery types have different ratings for charging current, voltage when charge is complete, trickle charge current and also temperature they can handle. Using a charger that is not designed specifically for the battery type you have can cause the battery to be charged too fast or too long, which can shorten the life and capacity of the battery - and worse, could cause unsafe pressure buildup.
No, it is not recommended to use NiCD batteries in place of NiMH batteries. They have different charging characteristics and capacities, and using them interchangeably can lead to potential damage to the device or battery. It's best to stick to the battery type recommended by the device manufacturer.
