The ROM in the very early units had a bug that used up the batteries much faster than expected, in particular drawing significant current even with the calculator turned off.
If your 49g+ ROM version is less than 1.23, download the latest ROM from HP's web site.
Well, they say that the real bug was that the processor supplier made a change without informing them, but I'd say the the bug involved not thoroughly testing that the very first production units actually worked as expected. What were they thinking?
I would hope that the 49g+ would draw current from the backup battery only when the AAA batteries were low or removed.
Did you check the batteries before putting them in? It's rare, but a brand new battery can be bad.
Of course the battery life depends on a lot how you use it.
Writing to the flash and I/O take a lot of power. In general, the 49g+ seems to go through batteries faster than previous models.
