After so-so life from the Harbor Freight specials (usually of their advertised 800 cycles), I’m getting 3+ years and maybe 800+ cycles from each pair and have taken about 20,000 photographs and 500 hours of video. If someone could correct my thinking on this, I always had the notion that normal AA batteries last longer than ANY rechargeable AA batteries. I have all the time used normal AA batteries for everything. Many years in the past, I tried the Energizer rechargeable charger with there rechargeable batteries and it appeared I was altering batteries frequently and was not getting good life out of those batteries. I was finding myself charging batteries extra so than using them.
