TLP 4000c Charger
 

Started using the slow charge option, seems to take very long...with the slow charging how do I know when the battery is fully charged? Same goes with the fast charge, when it starts blinking does that mean its done? or will the fast go to slow charge when it finishes?

I own one of these acursed things.
This particular charger was designed for fast charging with auto switch to trickle charge, which isnt really a slow charge per say. When you do a fast one on lowest mAh rating, that would equal slow charging, and you can calculate the required time by formulas found on this forum. However if you do straight out slow charge you get... the beeping.
In general, slow chargin is supposed to be slow, ie overnight, also depending on power setting and the mAh capacity of your battery. And their type/age/cycles/discharged? etc
Hope that helped

Ah yea I know what you mean, but how do I know when the battery is done charging? Does the trickle make some kind of different beeping noise or what?

the fan stops

when used on fast charge mode, after charging it will start to trickle charge and beep.

Ahh ok, I was wondering why the fast charge started flashing, i assume just let it go till the fan stops eh.

The fast charge led flashes when it starts to monitor the full capacity of the battery. That's not the technical way to say it but it's basically the jist of what is happening.

Ahh ok yea, I just charged it now, it went to slow after charging. At first I always thought that when the flashing happened it was done, hah. No wonder I wasn't getting so many rounds outta my batteries as I should have, thanks guys.
