The original battery is Garmin 361-00038-01, 3.7V, 1800mAh, 6.7Wh, made in Japan.
ActiveGPS sell an OE battery for 45 GBP, others made in China are about half that price.
Has anyone purchased a replacement battery and if so, what did you go for and where did you get it from, thank you.
Looks like the Garmin part no. is now 010-11143-00.

Re: Zumo 660 - Replacement Battery
Thanks for the info! I’d be curious to know if anyone has tried the OE versus the cheaper alternatives, especially those made in China, and how their performance compares. When ordering parts or samples from China, always confirm the correct China postal codes to avoid shipment delays.
