Yeh ..I was leaning to taking them out for heat & as they may upset the swithmode cct. And...after a few years the battery will detoriate in capacity which will probably play havoc.
But the plus side is that leaving it in may also smooth the PSU, at least while the battery is good.
Anyway..."it's out with it then"!
And what do you mean "loose weight"...cannot you tell...I've been on a diet for the last 15 years...haven't lost anything yet though!
Thanks Martin.
