 I assumed you understood... a gelcel *separates* anode and cathode,
so you are not combining hydrogen and oxygen (actually H+ and OH-) to
produce water during discharge. Your "exothermic" reaction does not
apply... it's in solution.

 When you charge a gelcell, you produce hydrogen and oxygen, the
hydrogen escapes and you are left with an excess of hydroxyl
(OH-) ions, which the gel traps in an effort to prevent too much lead
sulphate forming at the anode during discharge.
