Why doesn't charging start immediately?

252Q17: My batteries are at 92%, the charger is connected to my recorder, deep
253 discharge is off. But charging doesn't start. What's wrong?
254A17: Charging starts if the battery level is below 85%. This is because
255 charging batteries that *are* already more or less full is not good for
256 the batteries and the end of the charging cycle can't be detected safely.
257 So it's better to start at a level at least as low as 85%.
258 If you want to have full batteries in the morning, leave the charger
259 connected over night. Charging will then start some hours later. The
260 second possibility: Use the Archos charging algorithm. At least,
261 your batteries will be full one more time. ;-) \ No newline at end of file
