Bought a couple of these

Bought a couple of these as standby. Versatile, as they fit lights that run on RCR123, but in most lights, can also double up as a replacement for a 18650.

The RCR123A batteries are performing

The RCR123A batteries are performing well thus far since I've loaded them to my IP camera. They appear to last longer than the third party types which fizzled out within weeks. Will need to assess the performance upon a recharge which is left to be determined later.
