Hello!

> ... so I assume this is a safe buy...

110% percent safe :-) I am not related in any way to this seller, but have already bought battery packs and other parts from him - like I would guess almost every other collector of HP calculators on this forum.

> Also, the output voltage is 2.4V, not 2.8V (2 x 1.4V) as suggested in Hibiki's last post. Is this OK?

That's no problem at all. The original NiCd batteries had 2.4V so this is what the calculator expects to get from them.

> Would it be OK to charge this pack in the calculator, or should it be charged outside (if so, how - take it apart each time)?

You can safely charge this pack in the calculator but be aware that it has four times the capacity of the original pack, so will require four times as long to charge (more than a day!).

Regards
Max
