My Canon S50 camera, bought in 2003, could use a new Li-ion rechargeable battery, NB-2L, or NB-2LH high capacity. There is a vast difference in prices online, whether standard 570mAh or 1700mAh.
How can a person know which ones are junk and which are recently manufactured fresh quality batteries? I see no mfr. date on my existing ones, so how can I trust that what I buy now isn't knock-off junk and/or already several years old with little ability to hold a charge anymore?
