Hi all, after having my PRS700 for a week and having recharged it three times already, I thought I would do some research on how to care for and extend the life of the lithium-ion battery. The following is quoted from the windows help on my PC.
Note: If you frequently drain and then recharge a lithium-ion battery, it can quickly lose its ability to hold a charge. The practice of completely draining and then fully charging a battery is advice that applied to nickel cadmium (NiCd) batteries and, to a lesser extent, nickel metal hydride (NiMH) batteries. Lithium-ion batteries last longer if you charge them often, a little at a time, and maintain a minimum charge of about 40 percent capacity.
Using the sidelights on my PRS700 drains my battery quicker than expected. Reading at night with only level-1 lighting seems to drain my battery quicker than the 8 hours mentioned in the manual.
Playing with the search funtion on the PRS700 also seems to drain the battery at an alarming rate.
The term "frequently drain" may not apply to readers who do not use the lights on the reader, but it certainly applies to my need to do frequent recharges.
Since the battery is not accessible on the PRS700 (as far as I know), I thought this info might be useful for those who want to extend their battery life.
My plan, if I can, is to follow this advice and charge my battery often, a little at a time, unless someone can explain why this is not a good idea.
Long life to you and your battery
