| pandora[m] | <josch> "i'm now draining them to zero..." <- Don’t do that! U will damage them! Cycle ur batteries and then match them by capacity | 05:40 |
|---|---|---|
| josch | pandora[m]: hm? what do you mean? | 06:43 |
| josch | how will getting down to zero damage my cells? | 06:45 |
| pandora[m] | https://community.mnt.re/t/battery-is-not-charging/270/63 | 07:22 |
| pandora[m] | U start to change the battery chemically | 07:22 |
| josch | pandora[m]: how is this post relevant to my situation? My cells never were reversed and never under 2.5 V. | 07:26 |
| JC[m] | I was typing out a response regarding the dangers of exceeding the recommended depth charge for certain battery chemistries, but now I'm confused. You mentioned "getting down to zero" where I assume you mean 0V, but now I see that they didn't go under 2.5V. I haven't caught up on this thread in a while, so maybe I'm missing some context. | 07:28 |
| josch | my problem was, that my reform switched off when the oled display still showed 35% charge remaining | 07:30 |
| josch | at that point, two of my cells were down to 2.7 and 2.5 V, respectively while the rest was at 3.2 V | 07:30 |
| JC[m] | Oh ok, sounds typical with my experience. | 07:31 |
| JC[m] | Haven't experimented lately, though. | 07:32 |
| josch | so i replaced those two cells and tried getting back to zero | 07:32 |
| josch | which worked! | 07:32 |
| JC[m] | The references to zero (assuming 0V) is the concerning part. It's good if you can resuscitate the batteries (hence my post in the thread linked above) but generally comes with a long list of hazards, so it's not good practice to deplete them too low if it can be avoided. | 07:37 |
| josch | oh | 07:38 |
| josch | i didn't mean 0 V | 07:38 |
| josch | i meant 0 % | 07:38 |
| josch | as i mentioned here yesterday, the lowest volatage was 2.5 V | 07:39 |
| JC[m] | Ok cool | 07:39 |
| JC[m] | Just had the ! go off during passive scrolling lol | 07:39 |
| josch | i also have the new battery boards, so my cells shouldn't go down too far anyways | 07:40 |

| pandora[m] | Oh sorry I thought u meant 0V | 09:44 |
| pandora[m] | It sounds that two of ur cells just degraded quicker than the other ones. It is still best to measure the capacity and re-match them to get consistent readings. | 09:49 |
| pandora[m] | If u use cells with different capacities,their voltage will collapse at different times and u will have a laptop that shuts off above 0% | 09:49 |

| noam | I plugged in the reform last night, unplugged it this morning, and it failed to turn on [system controller was looping]. okay, fine, plugged it in, checked the battery levels and >6V overall | 15:00 |
| noam | :( | 15:00 |
| noam | Guessing the batteries were like this last night and I didn't notice :/ | 15:01 |
| abortretryfail | I wonder if I should stock up on spares. These are very cheap. https://batteryhookup.com/products/copy-of-100-a123-18650-apr18650m1b-1100mah-lifepo4-batteries-new | 15:03 |
| noam | O_o | 15:05 |
| noam | I was just looking for new ones and couldn't find any *anywhere* | 15:05 |
| noam | Do you know for sure that those are legit? | 15:05 |
| noam | Because the pricing isn't just "cheap", it's "implausibly cheap" | 15:05 |
| abortretryfail | They're a surplus/auction house. Everything they sell is cheap but odds are it won't be there in a week or two. | 15:06 |
| noam | Ahhh okay | 15:08 |
| noam | O_O https://batteryhookup.com/products/300-pounds-of-modem-batteries-2400-18650-cells-13 | 15:08 |
| abortretryfail | The medical CR2032s I got there worked. | 15:08 |
| noam | Could bid on 300 sets of reform batteries O_o | 15:08 |
| minute | these look cool, just 1100 mah is a bit smol capacityt | 15:08 |
| abortretryfail | Yeah, the kind of thing that gets to put into service and then changed out on a schedule regardless of how it wears | 15:08 |
| noam | They claim you can reasonably expect >90% of those to work | 15:08 |
| noam | minute: yeah, but given that it's impossible to find *any* anywhere else... | 15:08 |
| abortretryfail | minute: yeah, not great for long run time. I think they're for high current applications, but it's so cheap i kinda want to get some just to have extras lol | 15:08 |
| minute | for the "modem batteries" i don't see chemistry? perhaps not lifepo? | 15:09 |

| minute | 1800 mah, no tabs | 15:10 |
| minute | noam: which country do you need the batteries in? | 15:10 |
| noam | USA | 15:12 |
| abortretryfail | those modem batteries are probably Li-Ion. Tbh i think they expect the target market knows what to look for and how to test them. | 15:15 |
| abortretryfail | I've been salvaging cells from old laptop and power tool packs for a while now and I use them in all my flashlights and a few USB chargers and stuff for radios | 15:16 |

| abortretryfail | ^ good plan. :) | 15:36 |

| noam | I... I'm kinda worried this might be a battery connection problem, again :/ | 15:42 |
| abortretryfail | Hopefully it's a loose connection and not a cell with an internal short | 15:44 |
| noam | The only other battery issue I had was a trace on the board that fried due to a loose screw shorting it | 15:45 |
| noam | It's... possible the solder job there wasn't good enough, and came undone? | 15:45 |
| noam | I'll need to check | 15:45 |
| abortretryfail | oh... uh, maybe don't charge any batteries with that machine until you have checked for damaged components. | 15:46 |
