Rechargeable Batteries ?

Hi , I got my first Digital camera yesterday Canon A75 and have read many reviews and as far as batteries go they say to get NIMH 2100 or better.

Well i am in a small city and have been to many of the stores and the closet batteries i found were Duracell 2050.I don't like to order anything online and am wondering will these batteries be OK.

What is the difference between the 2100 and the 2050 is it just the 2100 will last longer.

Also these batteries were the charger and 4 batteries on for half price for 25 bucks which is really cheap here in Canada.

Thanx

Anything over 1600, the cheaper the better. Get two sets. There is little difference. You normally will recharge before they go dead. I have used 1600 to 2100 and can't tell the difference. I dont shoot till they are dead.

Thanx Terry
