Question about Garmin Forerunner 305 GPS Receiver
Unit indicates charging battery while in cradle for aobut 3 to 5 seconds. Than indicates fully charged batery. Take the unit off the cradel and it goes dead.
Per all of the other solutions I've seen, I've downloaded all the updates, tried all of the resets.
Ordered a new battery for the unit. however, can't seem to find an easy way to take the unit apart to install the new battery.
Anyone know the easiest way to replace the battery at home?(No it is not the HRM)
Should I send it in to Garmin for them to rebuild for the $100 cost?
Unit is out of warranty.
To power the unit back on, press the "Mode" and "Reset" buttons at the same time. Let go of those two buttons, press the power button, and the unit will turn back on."

I had exactly the same symptoms..
A bit after your post but here's my experience….
Opening it up:
The plastic base has a rubber facing on the outside (surrounding the side buttons), but as far as I can tell it is a plastic-plastic interface that glued to unite the top-bottom with cement. As has been said elsewhere, there are no catches to worry about…
Run a thin but blunt screwdriver or knife around between the “rubber” surround on the base and the top (black) plastic, applying slight lever pressure as you go (be careful and you won’t dent the plastic).
Turn the unit over so the top face is down and the contacts away from you. Apply a gentle pull on the strap nearest you while levering with your fingers at the bend in the base…this should (or did with mine) allow the base to separate from the top.
Now it turned out there had clearl;y been water ingress in my unit, between top and bottom above the contacts, one in particular at the end had corroded significantly…and on using contact cleaner carefully there was no gold left on the worst one and the mating contact on the circuit board simply fell away….. Bugger!!.. that’s basicly screwed any plans for my self-repair as can’t solder between the 2 with nothing to bite one….
However, it's not all about me!!!..
If your issue is the battery itself and you want to replace, here’s what I found…
Battery is marked as follows:
“Garmin part 361-00026-00
3.7V Li-ion 750mAh”
But (of course!) Garmin has not designed this for self-service (or by the looks of things for ease of service by anyone, given amount of glue used!), so that part # is not for sale…
Anyway, the actual dimensions of the are approx H 33.5mm x W35.0mm xD 5.5mm
..so the Ipod 4G battery, although rated the same, would actually be too big to fit (being 46*32*4.5mm)
I haven’t done an extensive check (not needing a new battery now!) but you may be able to source something very similar (possibly slightly higher capacity?) from something that suits (Canon?) cameras or a PDA device?
To change you have to lever out the old battery (its fairly securely glued to the base) then sever the leads from the existing battery and reconnect to your new one…would need a steady hand and preferably aWill not power up out of cradle - 4927918.jpg glass!
Putting it back together….It fits really snugly…Just clean off old glue carefully by scraping, replace with a glue that suits plastic-plastic and won’t destroy rubber and all should be sweet….
(PS sorry my pics are a bit crummy!)
