Don't know what the book says, but outside the book, normal computer safety considerations, be careful of static.But wear protective eye gear at min, if you can get an anti-static wristband that plugs into the wall (to connect your wrist to the ground on your outlet by way of a 1 megohm resistor) for about 10USD, best to handle electronics that way, no cats or dogs, no shuffling on a carpet to "shock" a friend and then forgetting and instead working on the Q133. I put some tips on desoldering in a previous post,but mostly from the opposite side of the pc board, touch the already heated and "tinned" solder tip to one of the leads and feed in some solder, pushing the lead just a touch in whatever direction has the most room to move, at the same time, pull up just a bit on that part of the battery, then repeat as you move around the pins until the battery is a good ways out. At some point you'll feel that it's safe to pull that side of the battery to where one
of the pins is all the way out, then the next and so on.
Central ideas:
don't heat the pin or the trace(pc board) or the battery too long, as briefly as possible.
don't try to get the solder out of the holes first. That leads to disaster. Adding solder helps gets what's in there flowing and that's what you want to gradually work the leads out of the holes without applying force (force also can lead to disaster). Once the old battery is clear (and needs to be disposed of appropriately because its poisonous and explosive) then even apply more solder to the holes, then use the a large Soldapullt brand (my suggestion - they're reliable) solder sucker (not the braid) to suck it all out of the holes, use some flux remover to clean up the pcb around there (don't breath those solvents though or get them on your hands) and wella! the board is read to receive a new battery which can then be easily soldered.
if you have ANY trepidation about soldering, (or maybe even otherwise) I strongly suggest practicing first (it is an art) on some crappy old computer motherboard or VCR or scrap PCB from a surplus house something until you've got the hang of it. Get your chops up.
Way better to do that (solder is cheap) than mess something important up.
Batteries are about 8 USD.
A lot is redudant, but hopefully helpful

Found it.
Is there any special care I should take while removing it. Can't find
anything in the service manual about replacing the battery.
It looks ok though on the board. (no leakage)
