The Suunto HelO2 does have a user-changeable battery compartment but many of our customers still prefer our certified Suunto technicians to replace their batteries. As well as fitting the new battery kit we'll also perform a pressure and function test that will check the integrity of all seals, not just the battery compartment, and test the critical alarms and functions.
We offer both drop-off and post in servicing with your choice of either collecting once completed or we can post it back to you. If you are posting the unit to us please remember to use a recorded method and that you also include contact details and return address information.
The turnaround for the Suunto Suunto HelO2 Dive Computer Battery Replacement is 7-10 days days. We also offer a two-hour express service if you are really pushed for time - please note this is subject to availability, so check with us before proceeding.
We are one of the few fully authorised Suunto Level 1 service centres in the UK capable of carrying out all Suunto battery changes and servicing in-store. Not only do our technicians need to meet Suunto's stringent test standards, but our servicing department also has to meet certain environmental and equipment requirements including dust free and Electro Static Discharge (ESD) protected workstations, controlled humidity levels as well as the use of approved tools and genuine service kits. We also pressure test all battery replacements and repair work to four atmospheres to ensure all seals are watertight before returning the computer to the customer. You can find out more about the pressure testing of dive computers HERE.
Please note that due to the deterioration of batteries and o-rings we can only use our own stocks of genuine kits to ensure you get the maximum life out of your battery and optimal seal integrity. Our kits are carefully monitored and rotated to ensure our stock is always fresh.
Please note that servicing products are excluded from the free UK delivery offer as we use a suitably insured next business day courier service to ensure your equipment is protected against damage or loss.
