[aprssig] D7 batteries

I took one apart, but not to rebuild. I wanted just part of the pack for a cover to
keep the battery contacts from being exposed. I was running it as a tracker without the battery using the 12 V input.
The case is ultrasonic welded and not worth trying to rebuild.
You have to cut clear thru the case with a exacto saw.
After market batteries a reasonably priced any way.
I am on my third battery since I got it years ago before the D came out.
I have rebuilt many batteries, but I will not do that one.

I was thinking of asking this same question several months ago.

Both my Kenwood (dead) and the Batteries America batteries (past its prime) have had it, so I looked at this.   I also acquired some really nice, internal protection, flat 3.7 V 1300 mah Li-Ion cells for a job last year.

 On the Kenwood pack I was able to break free the sides up to the upper and lower latch points.   Unfortunately the top and bottom edges appear to be welded and I haven't been able to even find the parting lines around the latch parts.
  Along the top looks obvious, but many passes with the Exacto failed to break through.
At the bottom, I can't see where the parting line is around the latch parts.

 I was wondering if it is viable to just cut the pack-front aross the top and bottom, inside the real parting lines, and get things out then back in.

I was thinkin' perhaps 'someone' is willing to destroy one and take photos, just to see how things look in-side...(;-)
