Time budget is much higher because it's so non-urgent (I don't need them RIGHT NOW for my flash), internal resistance is almost irrelevant, low self-discharge is meh if it lasts a few months at low power draw in use, etc. Just pop em out, put some in off the shelf, charge them, put them on the shelf. Now, there are different use cases - like if I was using rechargeable batteries for (let's say) some home appliance stuff, I wouldn't really care if I needed to recharge them 2x a year or 4x a year. However, if saving money is your primary reason to make. from 13.99 from 13.99 Regular price 15.99 15.99 Save 2 EBL 4Pcs 1.5V AA Lithium ion Batteries 3300mWh with Micro USB Cable.

I want them to have a high current capacity / low internal resistance so that they can cycle a flash quickly, and preferably without getting too hot themselves. With secondary or rechargeable batteries, a charger can reverse the electron flow and as such restore. With primary batteries, that’s the end of it. Energizer Rechargeable AA Batteries (8 Pack), Double A Batteries 24.82. Thats very close to the 1.2 volts of a NiMH battery.

Thus, the battery is considered empty or ‘dead’. In fact, over the course of their discharge, alkaline batteries actually average about 1.2 volts. Rechargeable AA and AAA batteries almost always last longer, cost less, and result in less waste than single-use batteries. I want batteries that have a high cycle count before they start getting low on capacity, and I don't want duds. All batteries work this way: electrons travel from an anode to a cathode until the anode is out of electrons. Like, look, using them for photography stuff, I don't have an infinite amount of time nor do I have an infinite amount of space (or weight budget.) I want batteries that have a high capacity and low self-discharge. IMO, capacity per dollar is only one metric and for me it's not that important.
