Maybe it's tip to improve weak battery

[themanincage]

Hi guys ,
After having the new battery , I try to charge the old weak battery with the external charger overnight , then use it , I notice that the power meter going down little after a day use , specifically 90% level whereas in the past I used my PDA to charge it , the power level always drop down to 55% at the end of the day . Perhaps the internal power charger of the Exec is malfunction after long period usage . From now on , I will use the external to charge the battery for my Exec .
Does anyone out there have the external charger and pls try my experimental .
Regards .

maybe the external drains the battery fully before charging it? Doing this helps keep the battery conditioned in tip-top condition. I don't have time for this and always top up as I only have the jasjar mains adapter but I used to try to leave backlight on in weekend and fully drain battery before charging it

...yes with Ni-Cd batteries of 10 years ago but the worst thing to do with a Li-ion battery

but isn't there a safe minimum you should really discharge to?

There is NO point to discharge Li-ion batteries. That is why it has been developed. We wanted a battery we don't want to wait draining it more like to charge it anytime. So, the truth is not "we don't need to drain it" but "we must not to do it", because battery dies in a short time.
