| 2400C battery internal configuration? | |
| Posted by: techknight on 2015-05-11 16:36:20 My 2400C battery was gutted by a previous owner, with no hide and a hair of a picture or diagram anywhere on where the wires go. So, this might be a long shot, but does anyone have pictures, or know where all the wires go on the cells? there are several wires. all are cut, cells are gone. | |

| Posted by: techknight on 2015-05-11 16:58:04 ok. But it isnt going to help i dont think.... Also when I do figure this out, i will have to reprogram the EEPROM to reset the cell counter so it doesnt think its still "dead"  | |
| Posted by: raoulduke on 2015-05-11 18:48:18 On the 3400c's lithium battery board, the black wire is the neg lead; red is the pos; the two white wires connect to tabs between the 2nd and 3rd and 3rd and 4th (I think) cells - but either way go between +/-, and there's a yellow wire that goes to a positive lead. On yours, I'd venture - purely as an opinion, that the black wire (left on top of the plastic in your picture, possibly) is the negative lead; the red one on the bottom right is the positive lead, the two whites go to tabs. I am not sure about those two-wire braided black ones on the left or the black and red leads on the right. However, every battery I have seen - NiMH and lithium - thus far has a klixon thermistor (the black rectangle on two red leads on the 3400c battery), which it looks like yours could be missing, though I can't see behind the plastic or what the black thing is. (If that's the contacts I was going to say the leads might be connectors that are disconnected, but there should be five and I can see that the red and black leads appear separate.) I realize this isn't what you wanted but I get the impression no documentation exists on this, so you'll need to find a dead battery to break open or someone who's done it. I kept notes on my breakdowns for that reason, but I don't have a 2400c. (Would the EEPROM reset apply to any old battery board? Because despite getting it to recognize, I have not had success getting my 3400c battery to actually charge (or discharge). The NiMH rebuild was a little more successful.) | |
| Posted by: raoulduke on 2015-05-12 18:47:41 Again... sorry it isn't for the 2400. You'll have to find a battery out someone willing to Crack one and take pics | |
| Posted by: techknight on 2015-05-13 15:18:36 the lighting is too dark, and the pictures are too blurry to make out anything useful, but its possible the PCB circuitry is similar/same to make heads and tails of my battery. But without clearer brighter more megapixel pictures, I cant tell... | |
| Posted by: aplmak on 2015-05-13 20:02:47 Techknight I have a 2400c battery apart and still intact!!!! I prepped it for rebuild eventually.. It just has the top cover nicely removed with little damage.. I will take a few pics and send em to you!!!! Matt | |
