So the old (LCD/monochrome) dash can be replaced by the new TFT dash.   Do you think that one has a replaceable (or a rechargeable) battery?   AF1 shows the old dash for $153.85.    New TFT is $269.23 but you also need a new bracket for $56.00.

The manual only says that it's non-replaceable, however that could just mean that it's soldered in place so you may be able to get a replacement put in.

It's welded in, it is aluminum and cannot easily be soldered to.


My battery is very dead. Less than 0.5 VDC, should be above 3.0.



So I decided to replace the "nonreplaceable" battery by a different method. First step is to order these thingies.


The remove the welded-on stuff and solder on some wires direct to the PC board:

Another thing. The display must be disconnected from inside while still on the bike.


Many screws around unit. Most are little Torex screws.


Headlight must be removed. Remove the two nuts.


Take unit apart and then unplug the cable from its two connectors inside the unit.


Removing the thing was the more difficult part. Replacing the battery doesn't look all that difficult, but it will not be the same. It will be replaceable from now on in its own battery holder per above message.

Those little battery holders come in real handy.
ive used them to refurb some slot machines.  The e prom / main board battery was like a little stack of Sox heat shrunk into a little tube bundle.  When it craps, the board is pretty useless the moment power goesout all memory is lost.  Can't really find the OEM's so a lith like that is essentially a perfect replacement volt wise, but fitting???  THAT solves the prob, unsolder the old battery from the mother board and solder in those leads and viola you are good to go with a battery that is entirely replaceable!

I finally made it back to my house in Auburn, CA so I could complete my replacement of the non-replaceable clock battery. The job is completed. I only need to put my windscreen back on. But it all works. Keeps perfect time when the bike is shut off and on again in an hour and now there are now no errors (a bad clock battery will give us an "EEE" on bootup, but the bike will ride as well as ever).


Now my non-replaceable clock battery can now be replaced in one minute or so after my windscreen is removed:

Better yet. I put back on the windscreen.  Windscreen does not need to be removed to replace the clock battery. There is plenty of room, yet the screen will protect the battery from the rain.

I decided to bring this old thread up in case others need to change their clock battery.



A few days ago, my 2017 Zero DSR clock battery totally crapped out. "EEE"  on bootup and clock time was "00:00". But NBD, bike runs fine, and the error is only at startup.



Rainy here all day, so I decided to do the same modification I did to my Zero DS, since it's an indoor day.


The old stock 2032 battery measured less than 0.1VDC.


Those who have a 2018 or earlier Zero should consider doing this modification to make it very easy to replace the "non-replaceable" clock battery. You can bet it will crap out in the next year, if it hasn't already.


So I decided to check this old thread so I can remember how I did it. SR job is now all complete and works perfectly.


After the battery is replaced, the symptoms will NOT change until the clock time is set. All will be good from there.


There is a small switch on the battery holder that I linked to in a previous message in this thread. "on" is the slider toward the battery wires. I kept it off during installation and then turned it on.


The stock battery is a type CR2032. Its capacity is 225mAh. I could not find any in this house, so I used a CR2016, which is only good for 90mAh. So this battery will last less than one-third the time of the stock battery. I ordered the 2032's which will fit in the same holder, but they will be here tomorrow.  I now do not care much how long the battery lasts, as from now on, it will only take a few minutes to change.   Any 3-volt battery should work.


Expect the modification to take around two hours.  Soldering wires to the PC board is required, and these wires probably should be longer than you expect. The leads on the battery holder are not long enough for this job. Then you need to cut to the correct length for the new battery location & splice to the battery holder wire.

Nice to be able to replace the cell in a minute or two.

The clock in my daughter's 2014 S is still clicking away, as is the one in my 2018 S. 

[DonTom]

The clock in my daughter's 2014 S is still clicking away, as is the one in my 2018 S. 

I wonder if the clock in the 2014 is a different design that lasts longer. I wouldn't expect 11 years from the CR2032 clock battery.


The battery in my 2017 DS lasted six years, and the battery in my 2017 SR lasted 8 years. Perhaps around 7 years is average, based on my experience.
