Betty is our Garmin nuvi 2597LMT GPS that we bought off our older daughter a few years ago. The battery has been showing signs of dying so got a replacement one off eBay for less than $15 dollars. Battery arrived weeks ago and been sitting on the balcony computer desk and when I finally got around to doing the job could not find the bloody thing.

Tiny Torx screws !…do I have bits that small? Took a while to remember that we bought something like a precision bit set from a walkway trader at Chinatown (The Glen) – found it in the workshop.

The smallest one in the set is T3 and I need the T4, removed the screws.

Carefully prised the back off with a jewellers screw driver.

Unplugged the tiny connector and then had to use a smaller screwdriver to dig the battery out of it’s cavity.

Secured with a double sided pad thing, managed to peel it off in one piece to use on the replacement battery.

With the sticky pad on pressed the battery back in it’s cavity and plugged in the tiny connector.

When replacing the back make sure to work right around until the clicking sound stops, then go around one more time. Replace the screws.

Job done…and Betty has a new lease of life.
