EverActive NC-3000 Charger: Refresh Function & 100% Battery Rejuvenation Indication

Hello, I have an EverActive NC-3000 charger that has the "refresh" function. I have a question - if I enable this function to refresh old batteries, the charger will signal itself that the batteries are 100% refreshed, or should you just control it yourself?

In this charger, the refresh mode is based on several discharging / recharging the battery.
At the end of the whole process, the inscription FULL will appear and we can read the highest registered capacity (from discharge).
Usually, it makes no sense to call this function preventively more than once every few months, because we simply artificially waste these cycles from the "life" of a given battery.

I see that you know each other so I have one more question, in my opinion refreshing the battery is that how I have, for example: battery. worn out after a few years, and I would like to increase its capacity because probably after a few years its capacity decreased, then I do "refresh" unless I'm wrong, so I ask in what way is the battery refreshing done?

Charging the battery several times is to remove the so-called the "lazy battery" effect for Ni-MH rechargeable batteries. It is also useful for forming new batteries.
From experience, it seems to me at times an unnecessary function in the case of Ni-MH batteries during typical use - but it is useful in situations where our batteries lie unused for a long time, they discharge in a given device for months (very low current) or are usually used very rarely.
The function also gives good results when the batteries are intensively used and regularly recharged (without complete discharge).
As I wrote earlier, in my opinion it is not worth calling this function more often than once every few months or possibly every 20-30 cycles of intensive use / partial recharges. The function also allows you to track any degradation of the capacity of our batteries.

How to check the capacity of a given battery in this charger right after inserting it. Yes, according to the instructions, it shows the capacity after the test or discharge refresh mode.

I don't quite understand the distinction between 1 discharge refresh mode and 2 test mode.
1 W discharge refresh. It is a sequence of several charge and discharge cycles. The goal of this mode is to get maximum battery capacity . we use to obtain the maximum capacity of old batteries and "forming new cells to check their actual capacity" Sequence, charge / discharge cycles with capacity measurement

2 In test mode according to the instructions' testing of the rated capacity of batteries. New batteries may require several charging / discharging cycles to achieve their max capacity . Stages are charging / discharging and finally displays the actual capacity.
Rechargeable batteries that achieve a lower value than declared in this test should not be used (thinking about it, I would give it to the discharge refresh mode

To sum up, in both modes it is ultimately the same to achieve maximum capacity. There are charging / discharging processes in both cycles.

Ps. If the correct charge is 1/4 of the battery capacity, what value should I use for the "discharge refresh" mode? According to the instructions, the discharge current is always 1/2 of the charging value. Ps should I change it?

To measure the capacity of any battery, you must first discharge it. There is no other method. No charger will show the capacity immediately after inserting the battery into the charger - and even if the charger has some indicator of the current level of charge (I doubt), in the case of Ni-MH batteries it will be a divination of coffee grounds ...

As for the Everactive charger.
In my opinion, the Discharge Refresh mode is suitable for eliminating the lazy battery effect (or resuscitating old, dependent batteries) and lasts about 3x longer than the Charge Test. As we have batteries in good condition, it makes no sense to add additional artificial cycles - I would rather not use Refresh on good / new batteries. Both modes at the end will show the real capacity of the batteries (from discharging).

In Discharge Refresh mode we set the discharge current (charging current will be 2x higher), while in Charge Test mode we set the charging current (discharge current will be 2x lower).

1) If I will not use the battery for half a year, leave it completely discharged or charged?

2) Do you always charge NiMH batteries via the CHARGE or DISCHARGE / CHARGE functions

I know that they have no memory effect but what will be the best for such a battery?
