Hello & Welcome to Just Answer,
I just did a search for that battery on Amazon, and see quite a few vendors that list this battery. I have a link to the search results below.
Zumo 550 replacement batteryhttp://amzn.to/1JjMb3t
NOTE: I see a few mixed in there that are NOT for the Zumo, so make sure you pick the right one.
Please let me know if you have any more questions.
Thanks, ***** *****
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
Hi again and thanks for that information.
If you mean "repair" when you say "refresh", the answer is "perhaps".
I say this because Garmin has an "Out of warranty" repair page (link below), where you can select the unit model number from a pull down list. When I selected "zumo 550 (BMW)" I DID see that they may offer repair on that device.
There is also detail on that page about the process of returning the device for repair, and I always recommend that you contact their support folks by phone to verify that that repair can actually be done.
I hope this helps. Please let me know what you find or if you have any more questions.
