I have a undien cordless phone with a 3.6v 500mah ni-cad
I cant find the model number (bt-905s)on the dse or jaycar websites
Is it safe to use a 3.6vni-cad phone battery with a different mah rating e.g 800 or 1000mah
also I see they are allot cheaper on trademe? e.g $5 as opposed to $30 should those ones be avoided?
Also should i stick to ni-cad or could i use ni-mh?
