HP 25 low battery indication at 2.6 v

[Peter Klein]

My Panamatik-enhanced HP 25 has a small annoyance. I run it on Eneloop rechargeable batteries. The low battery indicator (multiple decimal points) comes on at slightly over 2.6v. It also did this before I installed Bernard’s ACT board (standard, not Low Power). So the problem must be somewhere other than the ACT. Is there a component I could replace that would fix this? Is it worth doing?

This must be a known issue, because Bernhard included a setting that will disable the low battery indicator. With this done, my calculator works correctly down to 2.2v (measured with no load). Then the display starts to flicker as if a program is running. Nothing has been lost or scrambled when this happens. So far, anyway.
