HP 41CL - Power Consumption

[Neve]

I have been using these exact same NiMh rechargeable batteries for years now, and they seem to hold up at least 1.5 to 2 months when not in use. I usually recharge them every month, which is the rate at updates are usually released. But when I forget, the next month they’re still good, albeit they fail in the middle of the update cycle.
One thing I did notice though, I tend to put them in my charger in the same order I take them out of the calculator, and the second one from the left, is always the one with the lowest reading and, consequently, the longest to complete charging.

PS: I recently updated a V5 CL board with a Time Module Clone from Monte. I haven’t noticed any significant changes so far. But again, it hasn’t been long enough for me to really notice anything.
