Those figures show the capacity of the battery. For example, a 1200 mAh battery could supply 1200 milliAmps of current for 1 hour of operation. Of course, your actual usage will vary. And yes, higher is better in the sense that it means more time between recharging.
BuddhaTB wrote:2.) There are so many chargers for these things. Some that are quick chargers which take 1 hour to charge and other charges that take 7 hours to charge NiMH batteries. Is there any disadvantages to the quick chargers, like if they would reduce the life or how many times you can recharge the NiMH batteries? Any good brands you would recommend for a charger?
I have no specific recommendation, but unless you have a need for fast charging, slow charging is generally easier on batteries and makes for less expensive chargers.
BuddhaTB wrote:3.) Do NiMH batteries have memory in them like how Alkaline rechargeable batteries do. Where you have to charge the batteries when they are completely discharged or else you will decrease the life span of them when you charge them often? Or can NiMH batteries be charged whenever they are low and will have no effects on the lifespan of the batteries?
I think you meant NiCad, which are notorious for their memory effects. But to answer your question, no, NiMH batteries do not have memory effects. They can be topped off whenever you want without significantly reducing their lifetime or capacity. Some people actually recommend not allowing a NiMH to completely drain before recharging, so in that sense they are somewhat the opposite of NiCads.
I bought a Lithium Ion battery for my camera from this outfit:
They gave me good service.
