Equalizing

Hello from the southern french Alps!

In my house, my 12 OPZS batteries have been in use for 10 years. I think they should be equalized somehow. I tried:

  • the manual procedure (switch to charge only, back to on, back to charge only). No result.
  • Using veconfigure: the automatic periodic equalizing only catches with tube traction opzs. Mine are plates.

Shoul I dare set veconfigure to tube traction batteries or is there any other solution?

Thanks

Lionel

@Lionel SEYDOUX

It is probably not a good idea to equalise now. If they have been from the beginning it will be ok though. If they have been in use for a few years and not equalised at all they will have sulphated, they may shed alot of material and short plates internally.

Did something similar not on OPZs though, but still lead based, had been in the system 5 years never been equalised and killed the batteries.
