    life of cateye computer batteries

    Does anyone know what the typical life of a battery for Cateye computer are. I have two on sepearte bikes and it seems that they keep all the data, but registering the magnet for speed, cadence, is intermetitant.

    I have checked the distance of the magnet to the sensor to make sure it is correct. I've also checked the cable to see if any shorts, and I can't find any. Any suggestions?

    What happens to mine ... more than occasionally ... is slight oxidation on the connection between the mount and the back of the computer.

    I use fine sandpaper (and should use a dab of dielectric grease) to clean it up.

    Solves the problem.

    I have to do it a couple times a year, though.

    You can clean the contacts with just a pencil eraser too. Works well on old computer parts too.

    You might also try replacing the ferrite magnet with a much stronger neodymium magnet. It will give you a lot more room for error when it comes to the magnet to sensor proximity.

    I may replace the magnet. The chrome coating on my mt bike is starting to wear.

    Most likely the contacts on the back of the computer are corroded, or there may be some damage to the wiring.
    The battery in the computer should last at least 2 years.

    My track-record for the batteries has been a year. That's when I'll start getting no or erratic readings. I haven't, yet, had a problem with the contacts. Nor do I ride them in the rain.

    My Cateye computer last about 3 years, but if it's wireless the sending unit battery last about 8 to 9 months.

    If one or both of your Cateyes are less the 2 years old, Cateye will quickly resolve your issue.

    All of my Cat-eyes are wired and I've had batteries last 5 years and more.

    +1 on cleaning the contacts on the back of the head and on the mount. A pencil eraser is a good cleaner and a small dab of silicone grease will keep out water and crud. With any reasonable care, these things are super reliable.

    Per some Cateye manuals I have wired compute batteries should go about three years and wireless one year, dependent on usage. The average is listed for 1 hour use per day as I recall.

    What's interesting about that is that I've found the replacement batteries to last longer then the factory installed batteries. I still have an old Cateye that is sitting in my tool box that's about 23 years old, and the last time that battery was changed was 9 years ago before I got the Wireless, and that thing is still displaying! Of course it hasn't been on bike all those years either.

    The OEM batteries ... just like on so many Asian imports ... aspire to be crap.

    Really low mA-h, or similar.

    It's almost worth changing out batteries on any of these gizmos on day 1.

    Both my Cateye's - Strada Wireless - are obviously wireless. I should have pointed that out. Anywho, BatteryBob has the batteries for cheap - and no shipping charge. So I don't mind putting in new ones each year.

    My experience is that number is very conservative. I use my bikes well over 1 hour a day and the batteries still last much longer.

    And that was the OEM batteries which, IIRC, were Panasonics, and are not junk.

    It ended up being the contacts. I never thought of that. I have have a few years on each of the bikes. Still going strong. Just thought it might be time to switch when they weren't working.

    Any rain involved? Mine got rained on one time and the cadence stopped working until I did a hard reset. That was about 1000 miles ago and I haven't had any trouble with it since. As for duration, mine is 3 years old and running on the original battery.
    I like fat tires and I cannot lie...

    I'll just chip in here, when you do replace the battery, avoid getting fingerprints on it, the oils from your skin will give a small pathway for current, the batteries have so little capacity ( compared to say, an AA ) that the little current draining across the fingerprint is a noticeable loss.
