Rechargeable AA battery help

Cant see as the charger itself makes much difference, I use an old Uniross from argos, it has a 5 hr timer, charges my Eneloop & other Batts OK.

Charge time depends on the charger output and the battery capacity. 5 hours may or may not be right for your batteries. Check on the link above.

As a long time rechargeable battery user (photography and audio recording) I've learned the hard way that it's one of the quite rare areas where I really do find a difference between brands and 'own brands'.

I used to buy 7dayshop's own brand batteries (and I've had several of their chargers down the years) but have found that Duracell or Energizer have a lower failure rate, more battery to battery consistency, hold their charges better and last longer overall.

Likewise, the charger I now use for all AAs and AAAs is a La Crosse intelligent charger I bought in the States.

A quick check on Amazon reveals this, for example, which appears to be the same product

I'm not sure about Eneloops yet. I've got sets but you trade lower capacity for longer shelf-life and I've had some drain unexpectedly, though I suspect that was because the device I was using them in was using current even when nominally 'off' - in which case any battery would flatten.

I would say buy decent batteries in the first place, use an intelligent charger (not one of these archaic time-based ones) and fully discharge/recharge even NiMHs every now and again to minimise memory effect.
