[TenTec] Orion Backup Battery

[Rick W]

Thanks for pointing me in the right direction Sinisa.  I sent a note to T-T and they have it in stock.

The SNAPHAT battery pack is available from Ten-Tec ($10 + $6 shipping) and Digi-Key ($8.19 + $8 shipping).  I'm just not sure which version is used in the Orion the 48 mAh or 120 mAh (T-T didn't specify).  It looks like both will plug into the same socket the only difference is height with the 120 slightly thicker.

I'm about to place an order with Digi so I'll probably go that route.

73,

Board A7, schematic file 81917_13.PDF, chip U501 (M48T35AV).

With DIP version of the chip, the battery is an integral part of the chip.

With SOIC version of the chip, the battery can be separated and replaced 
(SNAPHAT).

For details see the STMicroelectronics datasheet.
