The cells in my phone have insufficient capacity to finish a long conversation, so I thought it wise to replace them. The new cells do not operate the phone at all. Upon checking the new cells, I find them to have a terminal voltage of 1.2 volts with a 22 ohm load. This is as advertised. The old cells, however , are of chinese manufacture, labelled KAIFENG Ni-MH size AAA 1.2v, have a terminal voltage of 1.4 volts into 22 ohms.
There are 3 handsets with this phone ( BT Synergy), none of which work at all on the new cells, and all the cells sport a 1.4V terminal voltage.
Any ideas? There used to be some rechargeable alkaline cells about, but they seem to be long discontinued.
Does BT have any liability about the availability of consumables?
