Lumen: The lumen (symbol: lm) is a unit to measure of the total quantity of visible light emitted by a source per unit of time. 


mAH rating:  The mAH rating tells you how much power the battery holds. Since an AEG uses electricity at a constant rate, the higher the mAH rating, the longer you can shoot your AEG before the battery needs to be recharging. However, the higher the mAH rating, the larger the battery will be.

Nickel cadmium (NiCd): Years ago, the nickel cadmium (NiCd or NiCad, pronounced Nye Cad) battery was the only rechargeable battery there was. NiCd batteries charge very quickly; however, they generate heat when charging and must not be charged faster than recommended or they can explode. NiCd batteries discharge at the rate of 10-20 percent a month when not used. 

Nickel metal hydride (NiMH): Nickel metal hydride (NiMH) batteries have less of a memory than NiCd and can be topped off without ruining their capacity for storage. They hold more of a charge than NiCd batteries of equal size and their self-discharge rate is lower. They will therefore have greater voltage and more capacity for a given size.

For example, on a 3-12x50 scope, the objective size is represented just after the “x”, in this case being 50 millimeters. Larger objectives, such as a 50mm objective, allow for more light to pass through the scope, equating to a brighter image. The larger the objective, the taller the mounting rings must be also.
