Can someone please explain why only Avantree rechargeable batteries will work in these 'phones?
Why do non-Avantree batteries, even of the correct spec, ie the same Voltage and Amperage, not work? Do the Avantree batteries have some "secret ingredient"??
Also, are the "original" batteries available in the UK (it appears to be US only)?
