Charging battery of SL-C860 with international power adapter
« on: January 10, 2004, 09:08:14 am »
I am using an international power adapter from Dynamism.com (240 V) and the battery EA-BL08 (1700 mA). I am a bit confused since every time I charge the battery it takes ve..ery long time. To be sure I keep it until a LED switches off. In spite of that the battery is partly charged (even 70%) it takes 4 hour or more.

Does the power adaptor have the same output as the rignal Japanese one ?
Regulated 5 volts and  1.0 amps.

Assuming it does and is working correctly then should get the same results.

Also, not done a scientific analysis of the matter or anything, but the battery indicator on the Zaurus is not the best. All my units do show a full battery for at least a little while after chargeing fully though (3 large batteries used in various devices).

Yes, it does.

So, do I have to charge untill the battery indicator (LED) is off, or watch software indicator? Every time charging takes about 4 hours. I am afraid of overcharging the battery.

This is just my experiance, so if someone knows better please correct me.

But, the software indicator uses quite large steps. Hence it may show full even when partly drained until it gets to the point where it updates to 75%. Better option is to wait for the light to go out.

Having said that, I have actually found that sometimes the light does not go out at all (gets confused ?). Never had a problem with the battery as a result though.

Not sure how the Zaurus charges. Perhaps it does the final stages as a trickle charge as it were which migh explain the long time. Also keep in mind that it is quite a large battery most devices only have half that and so the extra charge time may simply be normal.

As some point, when I have an almost flat battery I\'ll time it and see when the light goes out.

Another simple test, after you have done a full charge (light out), unplug and replug the charger. Should find that the light goes out much quicker indicating it is working as expected.

All a bit fuzzy, but that just reflects my understanding of it I\'m afraid.
