Battery #2 has a charge of 30% of capacity....





Assuming I put them in the charger, and they charge at the same rate of time... wouldn't Battery #2 reach 100% and stop charging before battery #1 reaches it's full capacity? And since these chargers require *BOTH* batteries to be charging at the same time... wouldn't this mean that perpetually, when charged [AND USED] as pairs... battery #1 will always be at 75%?





In essence, this would lessen the battery life of the pair of batteries...





Then there's the "memory affect"... which would cause the other battery to "learn" a lesser capacity.

Am I correct in all my assumptions? It would explain why my rechargeable batteries seem to run out quickly.





If so... how do you avoid this? Seems one would have to have a charger that charges batteries as individual units and not in pairs... or are there other ways to keep your rechargeable batteries charging up to 100%?

I guess I was wrong about my theory as to why my batteries have such a shitty capacity. I guess I'll be buying some Eneloops and hope they fare better than the ones I have.

ETA: Sorry if this was a stupid question. I just had no idea how battery charging works, and I have heard of battery chargers that charge batteries as single units rather than pairs... but they are EXPEN$IVE
