|Battery Pack for HP 21|

My apologies for the lengthy link.
I recently bought an HP 21 with a 'repaired battery case'. In fact, the battery case was busted in order to accommodate 2 AA cells. It is not pretty and I have to use a screwdriver to 'pry' open the case to access the batteries. I can barely put the cover back on afterwards and it is in fact in two separate pieces. What a shame since the calculator works perfectly. I bought it because I needed a non-programmable for an upcoming test, and only an HP will do!! The charger that came with unit may be functional but I have not yet been able to test it.
My question concerns the ebay link above. Will this battery pack, stated as being a Sanyo NBP-25 battery pack for a HP 27 Scientific Calculator, work in my HP-21? If so, do you think the HP 21 charger would work with it, assuming it is functional?
P.S. I also bought a 32E, so I am covered no matter what!
