Zoop Novo "Battery OK" And Then Two Days Later....

[Buadhai]

My wife has a Zoop. I have a Zoop Novo. About a month before our dive trip I put both in Dive mode to check the batteries. Mine said the battery was OK. Her's said it was low. So, I had hers replaced.

A couple of days before the trip I test mine again and it was OK.

On the first dive of the trip I put mine in Dive mode and it said Replace Battery. And, of course, it would not function for the rest of the trip, Fortunately, I had a backup; an Apple Watch Ultra with Oceanic+ which performed well enough.

How does a battery go from OK to needs replacing in just two days of zero use?

Like all electronics they’re either on or off, there is no in between. Similarly, my Suunto transmitter was good one day the next it didn’t switch on. But then I had exceeded the recommended dives by 50 and the replacement time by a year.

Had the same experience some years ago...
Since then I always carry spare batteries for the transmitters and for the dive computers for the whole family, and we always dive with a backup as well...
You never know...

The cold can kill them really quick too, was it in the hold or in your hand luggage
