However, I have loads of Uniross mAh 2500 battery's does anyone know if they will change in this charger?

I don't see why not...however if cost isn't an issue I found this one, made for those type of batteries:

I have mostly negative experience with recharged batteries. They hold power for much less time and unpredictable when they will run out.

NiCads wren't great, but NiMH are pretty good these days, as are Lithium Polymer. What type were you experiencing problems with?

That's my experience too

Get some Lithium cells. NiMH and NiCd have very similar discharge curves. The area under the curve is great, and their average power is high, but their open circuit cell voltage drops from nominal to nothing in the last ~10% or so of their discharge period.
However, DO NOT charge LiPo cells in a constant-current charger designed for NiCd or NiMH, because overcharging them will ruin the cell and possibly cause it to rupture and start a fire. More expensive, but definitely worth it IMO.

Thanks, I'll give that a go

I have the same experience even on Duracell NiMH batteries. They slowly discharge within two week or so. The Kodak batteries are awful. Duracell.com advertises a precharged NiMH baterry that holds 70% charge for a year. Try that and report here how it works.
