It could be that easy to name the capacitance in mAh, together with a link to the test setup (such as 200 mA discharge current, 20 deg.

Do not eat.

Long story short:
Rechargeables with reduced capacity compared to the 2500mAh (and greater) batts out there, but with less self-discharge during storage.

Basically, Average Joe has 2 options in rechargeable land:

1) buy higher capacity Ni-MH and have them self-discharge quite fast if not used for a while (but being higher capacity, they might actually end up having more playtime when used partially-discharged than Eneloops of less capacity)

or...

2) buy lower capacity Ni-MH (Eneloop) and have them self-discharge more slowly. The other advantage with Eneloops is they can operate in cold temperatures far better than traditional rechargeables too, which can't do that well at all. So there is an extra benefit there, too.

In my experience, Sanyo's discharge claims are exaggerated (surprise surprise), but it's a good battery overall. I won't reject a good high-capacity Sanyo tho (they do make the best Ni-MH, IMO).

If rehcarging right before use (and not really storing for 'emergencies', the higher-capacity Sanyos will give you more oomph.

For storage, it's up to you. Higher temperatures will see accelerated self-discharge, so keeping batts cool would help here. Either way it's a choice betwen higher-capacity regular rechargeables or lower-capacity Enelooops to see which ends up with more capacity when you actually go to use them.

For working in lower temps (like in an external flash for a camera in the winter), Eneloops will do it far better than any other Ni-MH.]]>Jan 17th 2008 6:08PM
