First... I do not want to post this in Lighting and gadgets. The demographic is just too young, and there is way to much,,,, "Youthful bravado". I really want to say something else, but we'll keep it clean.
So, I run a Busch and Muller Ixon IQ headlight. Had it about a year, and have used it a lot, including cloudy days, mornings, and late in the day. (Besides night) So, the factory supplied rechargeable NiMh batteries are finally getting to the point where they won't hold a full charge. I've got alkaline batteries for backups in my bag, should they be needed. These originals are rated 2100 milliamp/hours. Any suggestions on what I should replace them with? Or, any to avoid? Or, are the various brands of rechargeable NiMhs on the market all about the same? (Duracell, Everready, etc.) Suggestions and experience are welcome.
