HP 3468A Rechargeable Battery Pack

[Johnboy]

Excellent information Dave, much appreciated !

it looks like the 2.8Ah 6V SLA batteries are getting harder to obtain, but the seemingly more common 4.5Ah is slightly bigger, so I'll check the available space before purchasing.

Interesting info on the calibration battery backup as well, I will read that with great curiosity ! and I may ask more question on that too !.

Cheers,
John
