It might be something to do with the humidity here in Thailand but most cells leak eventually although most dont leak until 24months+ after manufacture
The important thing is to realise that it can happen and be vigilant with your cells. Check them regularly. Bag them in periods of inactivity. And don't use past manufacturers recommendations. Any signs of leaking then bin them. We dive a bunch of different rebreathers and have used cells from many different manufacturers. These cells all came out of our old cell disposal bin and are all well past use by date. But they show that all cells can eventually leak.
