Of interest, the thing that led me to replace my battery (and eventually to write the instructions) was that my unit died about 1 month after I purchased it last year. Refused to see a satellite. I sent it back to TT for service, and received what I am sure to have been a refurb'd unit in return. Battery life on the refurb'd unit was only about 1/2 what I'd come to expect from my new unit. Could have griped, and probably should have, but was just happy to be back in service. So a year down the road, and after using my TT with a USB battery backup to wander the streets in Lisbon one day, I got fed up and went looking for a battery again. Fortunately, somebody here pointed me to a correct (read: direct) replacment unit, the one mentioned in the instructions. Prior to that, I'd only seen "similar" packs designed for other equipment that had other connectors or odd wire counts. These could have been modified to suit, but many wouldn't know which end of a soldering iron to apply to swap the connectors after cutting them loose.
Very nice tutorial by the way.
Just fine. Getting the same kind of use/charge that I had with my new 720 before they shipped me the refurb. Original unit died (looked like the SiRFIII chip gave up), and the replacement they sent was a refurb whose battery wasn't as good as I'd have liked. That's what prompted the entire thing.
Thanks, I am very glad to have found the posts of you both.
