Changing 02 Cells

[Major Clanger]

I was advised on Mod 1 to change them all at the same time. On Mod 2 my instructor recently gave good reasons for changing them out at different times, but also mentioned he flip flops between which of the two he thinks best. Sorry if this has been done to near-death elsewhere but interested in view points.

Good question, don't know.

What does the manufacturer reccommend?

I was taught seperately at around roughly 6 monthly intervals (ideally), replacing the oldest each time but there are lots of different opinions.

I just replace all of mine at the same time every 12 months or so.

I think I'd tend towards the latter option (staggered changing) mainly so that the odds of all 3 going belly-up at the same time (ie new duds or 3 at premature end-of-life) was reduced... however, since I'm still on APD's new cells, they die after a few hours so I've not ever had to change one due to old age yet!

I got a N@90 mini cell checker when they first came out. So I just replace them all at the same time and regularly check them, usually once a month.

When I change mine I normally change them between 3-4 weeks apart with Teledynes now quite regularly with the new cells as JT mentioned

A common theme among Inspiration users I dived with last year.

Are AP cells still failing? I had one go a few months back and they replaced all 3. So far, touch wood, they've been fine. Haven't heard of many failures recently. This could be down to them getting it right or people just accepting that there failing and get them replaced as routine without posting about it. As for the original post. I think I'll start replacing them near end of life but perhaps a month apart (assuming they reach end of life).
