Garmin 128 internal battery change

[NickRobinson]

Hi

Mine's died, loses data. Unit still works fine and I'd like to keep as it feeds my laptop and cockpit repeater.

Someone did a kit with info here (for a fee) but hasn't posted for a long time. Others talk about prising open the glued casing.

Anyone done it?

I remember opening one up, but I can't remember why now . Quite possibly to change the battery, I can't think why else I would have done it.

The case was not glued, just a few screws to undo.

I changed mine on a garmin 12 just prised open the two halves. It was an lr2032 battery . Best thing is to buy a bettery holder with wires attached. Trying to solder is a Bad idea. The batteries explode! when they get too hot. Talking from experience.

The parts are pennies from Maplins, but may only be a temporary solution; When I went to do mine I found it had already been done by the previous owner. Unfortunately the time between battery changes got ever shorter until it couldn't do a day on a single battery.

That's useful to know, mine is in a dry nav station so I may try taking leads out to an external battery holder if that happens.

Did mine just before christmas.

Super simple, undo the screws unsolder, and then resolder new one but get one with the tags already on it.

Should do it.

When you do it take lots of pics, you'd be amazed how many people will want to see them over the years! I wish now I'd taken more than I did!

I have never opened up my Garmin 128 (still fine at 15+ years) but am certain than the battery (by all accounts a tabbed 2032 size) will be a RECHARGEABLE version.

Rechargeable 2032 Lithium cells are readily available on Ebay, commonly designated as ML2032. Unfortunately these deteriorate severely when stored unused for long periods and my experiences with several ebay suppliers have been poor.

How would you tell its rechargeable? I saw no evidence of this on the one I did which had a tabbed BR2032 which I replaced with a battery holder and cr2032 to make it serviceable in future. Presumably it would be a bad thing if the unit tried to charge a non rechargeable cell?

Edit: Never mind, a bit of Googling shows that there would be an r on the end, br2032r which there was not on the gpsmap235

 

[VicMallows]

How would you tell its rechargeable?

My assumption is based on:
a) I would be very surprised if a non-rechargeable cell would last 15+ years
b) The only 1 or 2 times is has lost it's almanac have been after prolonged non-use. On these occasions after a day of so being left powered up, almanac retention has fully returned to normal.

However my unit is an (old) GPS 128. If/when I need to open it up for any reason I'll post a definitive update

Edit: all the rechargeable coin cells I have seen have 'rechargeable' embossed on the cell, although the size may only be marked an e.g. '2032'

I'm sure there are plenty of computers still going after 15 years with the same CR2032 BIOS battery.

Yes, I wish I'd taken pics of an exploded cr2032 battery all over my kitchen ceiling. I was so lucky just to have turned away at the right time.
