I know this has been discussed here before, but I thought I'd share my
recent experience.
I have a 3 1/2 year old Nuvi 270 which suits me fine. It's battery has
degraded down to about an hour of life when disconnected.
Since I depend on it to find my way back to the car or hotel when in a
strange, unfamiliar place, I want the original 6 to 8 hours of battery life.
Garmin charges a flat out-of-warranty fee of about $70.00 for any repair.
I chose Batteryship.com, after looking at the choices listed here, for their
replacement battery and toolkit, for $22.95, with free shipping.
The replacement was without a hitch, after realizing the serial number/model
number adhesive strip had to be removed (carefully!) to expose the two
screws beneath.
The plastic case snaps apart with the tool provided, and it does take some
dexterity to deal with the tiny, fragile parts.
So, if your Garmin battery is on it's last legs, consider this path. I think
it was well worth it.
IHTH,

Jack R.

I used the same Vendor and was very satisfied with the little tool kit and
directions. Saw a couple of YouTube videos relating to replacing the
battery and then went at it. It took about 15 min to make the battery
change with the most difficult part of the task being the separation of the
unit into it's two halves. The battery was originally held in place with
some type of Silicone adhesive---I used a small piece of double backed tape
(carpet tape) and it worked fine. The cost was just about $20 with free
shipping. So far the replacement battery has performed even better than the
OEM battery. If you run into the need of a battery change--not to worry,
thinking about doing it is worse than actually tackling the job.
