If you visit flashlight sites such as Budget Light Forum you will find recommendations on which batteries get the most positive reviews. Those are all well known brands such as NCR/Panasonic and Samsung. There are lots of sources for these batteries far less expensive than $24. I've compared different 18650 batteries in the same bike headlight. My favorite is NCR/Panasonic 18650B which have an honest 3,400 mAh rating. Some of the cheaper Chinese made batteries with optimistic ratings ran the light one fourth to one half of the time before needing recharge.
