What is the difference between GP NiMH rechargeable 650 and 850 batteries ?

Question

Can I use GP 850 batteries in a DECT phone that is specified to use GP 650 batteries ? Will using GP 850 batteries spoil the DECT phone ?

Answer 1

the real difference in the 650 and the 850 is how long they last if the 850 will fit then it will be ok
