Clarification on "I ignr first" parameter for NiMH in cheali-charger
SERG
"In the cheali-charger settings for NiMH charging, there's a parameter called I ignr first (e.g., set to 3m). Based on the firmware's notation (m for minutes, mA for milliamps), 3m clearly means 3 minutes.
Could you please confirm the exact function and logic behind I ignr first Xm?
Is it correct that it disables the -ΔV peak detection algorithm for the first X minutes of the charge? (Ignoring any voltage drops during this initial period to prevent false triggers on the initial voltage dip common in NiMH).
Does this timer start immediately when the charge begins?
Is this parameter solely time-based, or does it interact with other conditions (like current level)? (I initially thought I might imply current, but the unit m indicates time).
Are there any specific recommendations for setting this value based on battery capacity or charge current? (e.g., when charging very small batteries with low current, is reducing Xm below 3 minutes ever advisable?).
Understanding this parameter's precise role would help optimize NiMH charging reliability, especially regarding false -ΔV triggers early in the charge cycle. Thank you!"
