Always pack a spare: You just set up your equipment for your first dive adventure of your vacation in Saint Somewhere. As you press the activation button on your Suunto wrist computer it goes through the diagnostic screen and what do you see the "Low Batt" Icon appears. The worst thing that can happen on an outing has just happened, No Computer! Don't leave on a trip without a spare battery kit. Why ruin a great day because of a few dollars in parts. If you're planning a vacation or trip this is a must have item to bring with you. Meets factory specifications and guidelines. The battery kit includes a new 3V lithium battery, o-ring grease and compatible o-ring.

Review: Worked! - OK if you do Suunto dive computers - you know they have one achilles heel - the battery replacement. usually it's a 100$ job at a shop. yes, yes, yes - they pressure test it - i know. But for a few bucks - i can do this job myself - and the computer was out of warranty anyways. So i'm quite happy to do this job myself. Everything i needed was in the kit - EXCEPT the hex screwdriver. Make sure you get one - you'll need it to take the screws off the back. Other than that - did it myself - silicone lube on the o-ring -and it's working fine.
Review: Beware of different brand/size batteries! - Update: the seller sent me the correct size battery after I posted this review. Great customer service. Apparently it’s the plastic battery housing that causes the improper fit. Original post: The photo shows a Sony battery, but it came with a Panasonic battery, which has a thicker rim and does not fit the Suunto D4. I’ve run into this issue before. Make sure you get the Sony CR2450.
