Maestro won't power up after being left on shelf

Yes, replacing the internal battery will resolve the problem. Totally worthwhile to replace yourself.

I do, but the email mentioned it would be $100/hr to take a look at it so I'd like to explore other options.

just put it up for sale "as is"  just let the buyer knows that it needs a new battery

I'll see if a new battery will revive it as my plan is to sell the 6700 and it would be nice if it had a working Maestro.

I have brought my Nikon Camera battery back to life and IT'S been working nicely 6 more years from when it was discharged below where the charger would recognize it.
(same with car and motorcycle batteries)

I had at the time a LAB power supply it had zero - X  adjustable output voltage and it had a current limiting adjuster...  It was a 2AMP maximum supply...  Quite precision device...  I hooked the battery to the supply set the current limiter and brought the voltage off zero...  I kept the current limited to 1.5A until the thing started obviously taking power.

As the battery started indicating less current I'd bring up the voltage.  Over most of a day I monitored the battery temp by touching before I turning up the voltage.  When it had come up to whatever I felt was a goodly amount I then plugged the battery into my fast charger. You don't want to rush things...  the battery for my Nikon was nearly $70 and I wasn't going to give up on it that easily...  As I've said the battery made complete recovery...

**** me I accidentally left the camera on overnight after that once more and went through the process again to bring it back, now I check for leaving it on, the thing won't auto off...  Anyway...

Some of these other batteries if not swollen, but just discharged may be recovered utilizing such a laboratory supply..  I ended up selling the supply on eBay as its only function around here was fixing an old battery twice in my life...

It is possible...  Erika DD

Russ, as you are already good with accessing the battery you could try charging it directly?

I would but you really need to follow the cautions and procedure I outlined in my post. Nothing worse than a battery explosion.  However a gentle touch could save you additional expense.  Unless you can't gain access to a supply that can slowly bring up voltage while limiting the current to a safe value.  Erika DD
