This has a more honest output than the battery in my nav. Anyway I wired it in no dramas and being lithium it was ready to go. I did charge it however. Problem was my nav is discharging internally somewhere and way beyond my abilities to fix it. This battery is a beauty though and will serve as back up for another nav. Really inexpensive fix to a dead nav or at least a cheap way to test if the circuitry is killing your battery. Don't forget when you chuck a lithium battery to put it in a bottle of very salty warm water. Let it discharge safely this way for a few days to make it inert then you can safely dispose of it.

This battery replacement for my TomTom Go 600 has been working very well. I first phoned TomTom and they told me it was too expensive to replace the battery. Was offered a 25% discount on a new model - GO 620. Followed Utube instructions, did it in myself in under 20 minutes. You just need the right tools for the job. A fine point screwdriver and a nylon spreader tool to "split" the two halves apart.
