Lithium Ion v's Lithium Polymer vs' what's new

[mclearg]

I have an application that requires some thought. We currently use a 7.4V (8.4V peak, 5.5V cut-off) 2400mAh Lithium Ion battery pack with PCB (IC protection) in our product.
My main problem is that the life cycle of the battery is 300-500 cycles and as it is currently molded into the product, there is a major remanufacture issue when the battery is beyond it's lifecycle.
What I would like would be a battery tray with a seperate battery, not unlike a mobile phone/battery set up. This would allow my clients to have two (or more) batteries and just swap them over when a recharge is needed. Is there a manufacture of such component packages?
Any help greatly received.

Why do some things seem so plausible at the time ............and yet so idiotic in retrospect?

Valence Technology can make battery packs of any description with power splitting and charging electronics. Best of the lithium phosphate group.

Thanks I'll have a look at them. I was kind of hoping that I could find a manufacturer that made off the shelf tray's and batteries, save me some cost as we are not a particularly high qty user.
