My book was no longer selected and my last read place was no longer being saved for me but it worked  ! |
Not long after I popped my Eneloops into my JBL, the "charge meter" dropped to three bars. I not alarmed by this since prechargeables, such as the Eneloops, do not charge up to the full 1.5v of alkalines and there is a tiny, initial battery voltage drop during the first month, after which the rate of self discharge becomes almost nil. Since then, the "battery meter" has remained at three bars.
One advantage to the NiMH batteries is they do not develop a "memory" if not fully discharged before recharging them. The reason this is an advantage is one does not have to wait until the batteries completely run out before changing them out. I would suggest doing so when the first low battery warning pops up. Just make sure the book has been turned off first so settings will not be lost. Since pulling the batteries essentially causes a reset, it will be necessary to hold the on button until the display comes up (2-4 seconds). It will take awhile for the reset to finish.
Since the current set of batteires are still doing fine, I haven't had the opportunity yet of trying Ghosthawk's trick of hooking up the USB cable to a computer so there would be power on the JBL during the battery change, avoiding the hassle of waiting on a reset.
