Need external battery charger -- they don't exist?

[SHAWN1369]

I've done my homework and found battery charging cases for the following samsung phones... i607, m610, m300, sch-u350/430/450, a580/870/930, u620, i770, sch-u700/706/740, sph-z400, a523, u540/550, and of course the m800.

Also, Moment m900 batt also appears to fit the Behold sgh-t939, Instinct HD m-850, propel pro sgh-i627, and code sch-i220.

What I can't find is any website that tells me battery dimensions. If I could match the dimentions, pic would allow me to guestamate contact placement, and logic says I could potentially purchase a charging case that fits and works.

HELP!!!!!!!!!

Finally had time to do the upgrade to the blackjack II charger to charge the phone AND an external battery, works great. Two people at this forum posted directions, one with a uTube link, some info was used from this original thread.
