GTR4000 Memory Error

January 03, 2021 - 08:14 am

I have a GTR4000 that has been stored for a couple of years and now that I've dug it out again, it is now giving me memory error that would indicate the chip with the internal battery is dead.  Not surprising given its age.  I looked for a BQ4013YMA-120, but it seems to be discontinued and I can't seem to find one from a reliable source other than Chinese sellers on eBay.

Should I trust putting one of these (probably knock-off) chips in my 4000?  Is there are compatible replacement chip that is currently being manufactured that would work?

thanks in advance!

Unfortunately, as you have discovered, these parts are totally obsolete and have not been made for years.

I don't think you have much to lose by trying anything you can find as your unit will be worse without it.

But, note that if you keep it powered up, it should work fine - the battery is only there to preserve data when it is powered down.
