NiMH Rebuild?
Anyone here done a NiMH rebuild? I have some ancient batteries from '01 (they literally have the ACROS code name on them) that I'd like to take a stab at rebuilding but would love any advice.
Also have a set of Lithiums that were "rebuilt" by MTO, but only throw red lights.

Often with the nimh batteries the chemicals will corrode the bms board.
some repairs can be made but they start to conduct internally along the vias inside then pcb.. and eventaully fail,...so even with new cells it won't work. I have new boards just waiting to be built and tested...as I use nickel cells alot I don't want to be without. However, it is often just the cells that are unservicable.. best... |

Hi Dorrington,
Im about to rebuild a NimH pack. What are you using to glue batteries. Epoxy or Hot glue or what. Any advice appreciated. Thanks Les |

Hi Dorrington,
What glue do you use to stick battery packs together?. In the originals it looked like some kind of epoxy. Thanks Les |

Hi Les,
I usually tape around the packs of ten just to hold them together. I use polyeurethene re-enterable potting compund (just enough to cover the bottom of the cells 1/4" or so). seems to work for me... |

....And to re-seal the lids I use Sikafkex 221...and a soapy wet finger to finish the seal....
