Battery life MK1

I have noticed the battery life on my MK1 is down.  I do 2-3 dives per day and now I need to change my dive computer at the end of the day. Any ideas?

  • I've had mine for 3 years now and I don't see much degradation in the battery.  I only do one dive in a day but it is usually a long one (2 hours) and the battery is fine.

    For example, I charged the battery to 98% on Thursday.  I did a 2 hour dive on Friday.  On Saturday morning I did a 30 minute walk with GPS and then a 2 hour dive.  On Sunday I did a 25 minute run.  Today (Monday) I did an hour walk with GPS.  My battery was at around 43%.
