Suunto zoop battery

[Rick07]

My suunto zoop novo battery is low is it worth paying a shop to replace it
I looked online doesn’t look to hard but it’s only about a tenner extra to have t he shop do it
.What are your opinions

It is a doddle. You can get battery, Oring and grease kits on eBay for around £6. With the Zoop you can use any sort of 2450 battery so Duracell, Energizer or Renata.

Do it yourself.
Test it in fresh water rather than sea or a pool.

Cheers will give it a go

They are really easy to DIY. The Novo uses screws rather than a twist off cover like the old one, but still really easy (you'll need the right size Torx driver).

Is it worth getting it done for you? Depends on your appetite for risk verses price. Sometimes getting it pressure tested will reveal problems like the pressure sensor failing too. But that said, I change my own but pressure test it afterwards - MrsT is a uw tog so very good with o-rings. It is pretty easy to do but just be very careful with that o-ring (many battery kits don't come with a new one). If it's not in the correct shape, or over-greased, or has collected dirt etc, you might get a leak. With a bit of care and the kind of skills most underwater photographers have developed, it's straight forward. You can also make your own pressure pot easily enough and test it yourself.

Is that the one you need a torx screwdriver for?

If you pressure test it yourself the technique is to put the computer under pressure whilst it is in air - once the pressure has been applied for a few minutes get the computer into the water and give it a shake to get rid of the trapped air under the cover and then release the pressure - you then watch for bubbles coming from the computer. If there are any then they must be from the battery compartment in which case there is a leak. As you didn’t increase the pressure when the computer was in the water then the water won’t have got into the battery compartment. Reseat the battery backing plate and recheck - check that the o-ring is really clean as even a hair / bit of dust will compromise the seal.

Thanks for all your help

The zoop critically depends on the battery size to make an effective seal (which is an utterly crap design - relying on a 3rd party part where the external dimensions can change quite significantly) - we had about 4 die in quick succession as a result of battery changes a couple of years ago when previously we never had a problem changing batteries dozens of times. For these my strong advice would therefore be to either buy the OEM replacement (which costs an arm and a leg) or stick it on ebay and spend the money you save on something where the battery compartment is sealed from the computer - like the Mares Puck - so if it floods you are only down a £2 battery and not a £200 computer.
