I have just got a really nice 97 which is working really well. However it seems to have restored batteries, but I have no idea how old they are.

When I try to read a card it works fine when on the power supply, but won't read when only on batteries. Everything else works, the printer, the display etc when on batteries - just not the card reader.

I assume the batteries must not be providing the correct power. But apart from a Multimeter and basic electronics is there an easy way of checking the battery pack against some spec?

If not, I will be looking for a replacement pack!

Many thanks

It could be the batteries in poor condition, however, the card reader uses less power than the printer, so it seems a bit odd that it doesn't work and the printer does.

The HP-97 charger cannot supply the power required to run the card reader/motor however it might be supplying just enough to add to the (I'm guessing) poor battery and allow it to work.

Does the low battery LED light during card reader or printer operations?
