I own a remote controlled boat, it's for angling purposes (a baitboat).
It's a sealed unit and the battery is inside with no access apart from
splitting the boat in two and getting to it that way - the boat is sealed
with black silicone.
When I bought the thing, the battery was dead and I enquired with the
manufacturer as to having it replaced - they wanted £90, but explained that
'the battery was not removable and had to be physically broken up' to
replace, so I thought 'fook that' and had a bash myself, this was last year
and the battery was indeed well glued in place and after much arsing around
with stanley blades and umpteen solvents, it eventually came free and was
replaced with a shiny new one at the pricely sum of £12.25p.
I used araldite two pack adhesive to mould it into the bottom of the boat,
which is made of a type of resin, anyhoo the fecker came loose last week in
France and was flopping about inside the boat, making it difficult to
manouvre, given that it weighs 3kg and it was either on one side or the
other and the thing was almost capsized on more than one occasion...the boat
is worth around £400, so obviously I'd rather not see it disappear neath the
waves, and I have just opened it up and the battery is indeed lying on it's
side.

The lifetime of this type of battery is estimated at 2-3 years, and it's a
year old now, so obviously it's gonna need changing at some point in the
future, so I'm looking for something that will hold it in place (bearing in
mind that the boat is carried by the hull, IE, the arse end) so i don't want
it to move, but WRT another replacement, I don't want it 'welded' in place
neither.
Obviously drilling, bolting, screwing et are all out, so what do i use?

Without a shadow of doubt the glue to use is Sikaflex caravan adhesive.
It remains flexible when dry and sticks like sh*t to a blanket. You
won't get it off so you'll have to fabricate a bracket and stick that on
with the glue.
