[comp.sys.laptops] Need Help Building External Battery Pack for Laptop

srm@dimacs.rutgers.edu (Scott R. Myers) (04/18/91)

I have salvaged from an old UPS 4 6volt Panasonic Lead Acid Batteries.
I would like to use them in a case as a backup battery pack for my
portable office (laptop,cellular phone,etc).  Questions I have are
concerning differences in voltage and amps.

1) My laptop (Sharp MZ200) takes in 9VDC 2.5amps converted from
household current.  The Cellular phone plugs directly into my
cigarette lighter.  I'm not sure how I should set up the batteries to
provide current to these devices and not blow them up.  Any ideas?
Also to add I would rather work with just 2 of the 4 6volt batteries.
(A little lighter on the shoulder).  Thanx in advance.
