GLOSSARY
When I discharge 4 fully charged 18650 Li-Ion batteries at 1A/slot together at the same
time, the plastic radiator grille gets hot, the metal (+) contacts too, but less so when I
discharge a single Li-Ion battery at 2A. What's wrong with me?
- Nothing. All is good. But if you don't feel comfortable with the high temperatures at full load,
how about discharging two batteries instead? You will be surprised how not hot the externals
get at reduced loads. In any case, no need to worry, the dissipated heat will not damage the
charger or your batteries.
The fan is noisy. What are my options?
- No, the fan is not noisy. The charger comes with a low-noise high-speed 30×30×7mm mini
ventilation fan, firmly clipped to the inside of the bottom. You can check.
I am trying to discharge a LiIon with 1.5 amps plus a NiMH with 2 amps but the charger
refuses to go higher than 1 amp for the LiIon battery. Why?
- Because of the higher nominal voltage of rechargeable Li-batteries MC3000 allows only one
busy LiIon slot to discharge such a battery at a rate higher than 1 amp; the presence of any
second busy slot will instantaneously limit all four active or inactive LiIon slots in their
respective maximum discharge power. This must have been explained before in the manual.
I've placed a flat top protected 18650 battery in the bay yet the slot info is still
displaying NO BATTERY. How to proceed?
- Check if the battery is inserted with correct polarity. Check if the battery terminals do make
proper connection with the slot metal contacts; shift, suspend, or tilt the battery, if needed for
securing the connection. 0V-batteries are displayed as NO BATTERY, so check if the battery
protection is tripped; click the slot number button to release the protection.
Can I discharge non-rechargeables such as Alkaline or Lithium primaries? I would like
to verify their rated capacities.
- Primary batteries don't often come with a capacity rating but yes you could compare
discharge capacities of primaries of different makes. Use BATT TYPE NiMH with D.REDUCE
option for discharging Alkalines, use BATT TYPE LiFe for discharging Lithium primaries.
Keeps me wondering, what does the term 'nominal' or 'nominal capacity, nominal
voltage, nominal charge rate, etc' actually mean? I read it so often here and there but
never cared to read up on it.
- Nominal is a word derived from Latin. The Latin word 'nomen' means name. Aha.
Does the charger have built-in protection against reverse polarity, short circuitry,
overheat, overvoltage, overload, stupidity, ignorance, explorativity?
- Do not misuse, abuse, or mess around. The device was built for proper responsible usage.
Understanding how to operate the device through its user-friendly interface is easy. For ease of
discussion it is helpful to introduce the following abbreviations:
1)
2)
3)
4)
[30] = program 30, …, [01] = program 1
#4 = slot 4, ..., #1 = slot 1
SNB = slot number button or its LED
SNB#1 = slot number button of slot 1
TOV = total overview
IMV = info message view in TOV
UCV = user calibration view in TOV
SOV = slot operation view
SPV = slot programming view
GSV = global setup view
DDV = diagram drawing view
CC = constant current
CV = constant voltage
To depress = to long-press, to press and hold
To click = to short-press, to press and release
To press = to either click or depress, doesn’t matter
Empty slot = a slot with NO BATTERY, i.e. the SNB is black
Ready slot = a slot with a blinking red-green SNB, i.e. ready to start the program
Inactive slot = an empty or ready slot
Busy slot = a slot with a solid red SNB, i.e. running a program
Finished slot = a slot with a solid green SNB, i.e. finished the program normally
Active slot = a busy or finished slot
Electric charge transfer = either charge or discharge
Routine = charging, discharging, or resting, as part of a program consisting of several
such routines
Operation mode = Charge, Discharge, Storage, Cycle, Refresh, or Break_in mode
Program = an operation mode tied to a full set of settings and with a program number
assigned to it
Program number = a program number is the program with this number, and not only the
number itself
To finish a slot or program = the busy slot becomes a finished slot
To stop a slot or program = the active slot becomes a ready slot
Cycle = sequence of at least 1 charging and 1 discharging routine, or vice versa
