cyclon battery top up ?

Forums

a have a 6v cyclon battery that has been around for god knows how many years and has never needed charging ! , I am going to fit to a  little old italian bike. I can access the top of the cell and wonder if after all these years a little distilled water may be beneficial to the gel ?acid  which is bound to have dried out a bit.Anyone tried this ?.

If it is the Hawker / Enysys cyclon type batteries, they are AGM and I did not know any maintenance was possible or advisable other than a recharge. I have never topped one up, or attempted disassembly (all my old bikes are fitted with them and I have only ever had one fail). I would wonder if they can safely be topped up and even if they can, would they still reliably reseal after disassembly / reassembly? Could do more harm than good. I would be inclined to buy a new one. There is a manual available on-line if this helps:
