Buy the higher capacity battery, e.g. 2500 mah aa, or 10000 mah d battery( large flashlight size ). Always store the nimh in the fridge with a full charge and charge them fully just before use. If stored at room temperature, self-discharge will be significant. "MAH" stands for milli-amp hours, the energy storage capacity of the battery as rated by the company and stamped on the side of the battery.

Consider the battery life, charging time, charging current, starting (peak) current it can supply for inductive loads should be high enough, weight of the battery should be a constraint if the battery is being employed for electrical vehicles.

Buy a good charger, not something cheap. Get one that has the capability to discharge batteries completely and fully recharge afterwards, such as a charger with a battery conditioner.

Check the capacity (charge storage); make sure that the battery voltage will work if replacing primary cells with an approximate equivalent secondary.
~Richard S, Quality Control, Leicester, UK
Consult with an expert. Don't use off-Chinese brand unless that manufacturer is proven. KNOW THE TRANSPORTATION REQUIREMENTS.
