MIB/NIB 33s & 35s and batteries

[Matt Agajanian]

Hi all.

At least a year and a few months ago, I bought a 35s from hp.com and a 33s from an auction site.

To this day, neither box has been opened. Should I open them so as to remove the batteries in the calc? Forgive my memory as I've forgotten how the two I use were originally packaged, if there were batteries already installed or not. Please advise as I wish to prevent battery leakage should there be batteries installed in the NIB/MIB 33s and 35s I've not opened.

Thanks
