I am using four CR123A Lithium 3V batteries in Arlo wireless video camera. I owned Arlo camera for a few years so I had a chance to compare longevity of several different batteries (Panasonic, Duracell, Energizer as well as off-brand rechargeable batteries). Every time I change the battery I write down the date so I can compare the longevity from each set of batteries. Arlo takes 4 batteries at a time.
Energizer batteries have performed the worst in my experience, on par with rechargeable batteries.
* Cold weather (i.e. spans winter): Panasonic 4 months, Duracell 2 months, Energizer 2 weeks.
* Warm weather: Panasonic 6 months, Duracell 4 months
Another data point I have is comparison with rechargeable CR123A Lithium batteries.
* Cold weather: Panasonic 4 months, rechargeable 123A 2 weeks
* Warm weather: Panasonic 6 months, rechargeable 123A 1 month
A note on Panasonic batteries. I have been burned when I bought Panasonic batteries from vendors other than Amazon, they appear to last significantly less (this happened twice). It is possible that other vendors are selling older batteries. So I always check the vendor and pay a buck or two more if necessary to get it directly from Amazon as it gets me several extra month of battery life.
You can find it on Amazon by following this link.
