Thanks for the guide. Used it to open up a Nuvi 265 because the battery had been left to discharge below the protection circuit's limit. Connected the battery leads (Green = ground, Red = voltage, Black = temperature) to a 5v USB charger for ~20 seconds to revive the protection circuit, and the unit is now charging again. If you're going to do this, know the risks. Thermal runaways in lithium batteries can be extremely volatile.
