A silicon based spray sealer should work, just make sure whatever you use
is air cured and not accelerated cured by using acetone or some other
solvent that may get trapped and eventually cause corrosion of the cells or
cell interconnects.  Even if it buys you a couple of years that is better
than throwing it away, just make sure it is safe and does not cause another
fire!
