Re: 2440 what kind of battery

Dave Casey

The Dallas chips don't have a low power input Vcc pin to my knowledge, so
any external battery attachment still requires you to grind the package.
You can also just replace the whole Dallas chip with a new one if they are
still available.

I may have the NVRAM with internal battery as SN B013872, so I may try
the grind and CR2032 trick. Or, could I add a larger battery like a 18650
(3.7 V fully charged) wired to each chip?
