Is my new La Crosse BC-700 working properly?

[joepa150]

A little background.

I purchased a 4 pack of Duracell/durloops (white tops) about 1 month ago. I just bought a Nitecore D10 Tribute Edition. I have used it for about 2 weeks. Today I decided to put the 2 week used battery and the other 3 unused batteries in my new la crosse on the refresh mode. That was maybe 7- 8 hours ago. The used battery discharged, charged, and now just started to discharge again. The 3 unused batteries are have discharged and now are charging. I am using the 500ma setting.

The maH on the used battery hovered around 961. The others all hovered around 1403-1432???

How much longer and does this sound like it is working?

The manual says about 8 hours for a full charge. I did hit refresh mode.

The BC-700, in refresh mode, can take up to several days depending on the discharge current selected. It will continue to discharge/charge until there is no further increase in measured capacity.

Wow! Is it safe to leave the house while the charger is on?

These measurements come from the first discharge of the partly-empty batteries, so expect them to be low. The mAh readings after the next discharge will be closer to the batteries' actual capacity.

At 250mA discharge / 500mA charge, it will take about 8 hours to discharge and 4 to charge, meaning 12 hour cycles. The last package of Duraloops I ran through took 3-4 cycles to finish.

I think they are all on there 2nd discharge now. Is it safe to leave overnight?

Also what should the maH should be and the V be?

I have a BC-900 (non-recalled), I've never had any problems leaving mine for days.

Final capacity is usually in the 2.00-2.06 Ah range. Voltage will hit 1.5 during charging, then settle around 1.3-1.4 afterward.

1. A little background.
   
   I purchased a 4 pack of Duracell/durloops (white tops)...
   
   ...Today I decided to put the 2 week used battery and the other 3 unused batteries in my new la crosse on the refresh mode. That was maybe 7- 8 hours ago. The used battery discharged, charged, and now just started to discharge again. The 3 unused batteries are have discharged and now are charging. I am using the 500ma setting...
   
   ...How much longer and does this sound like it is working?

1. Assuming 2000mAh AAs, the La Crosse BC-700/BC-900/BC-9009 can take *DAYS* to finish a REFRESH Function depending on the:
   • Cell condition (i.e. Older = Longer)
   • Charge Rate selected (i.e. Lower = Longer)
   .
2. +1
   
   
   
   Even if the CAPACITY increases by just 1 mAh, the La Crosse will initiate another REFRESH. Thus, this could continue for DAYS... (but, usually not with HEALTHY / VIBRANT cells)
   .
3. In a BC-700, I'd say yes.
   
   To-date, I have not read *ANY* reports of *ANY* overheating / meltdown problems with a BC-700.
   .
4. +1
   
   
   
   I use my BC-900 for my *CRAP* cells and my C9000 for my VIBRANT / HEALTHY cells. Thus, if I DO execute a CHARGE-type function on my C9000, I will usually follow that with (at least) a ~20% DISCHARGE and then load them onto the BC-900 for a REFRESH.
   
   As compared to the La Crosse 'TEST' Function (CHARGE/DISCHARGE/CHARGE/STOP), I prefer to use the 'REFRESH' Function (DISCHARGE/CHARGE/DISCHARGE/CHARGE...) to 'exercise' all of the cell's chemicals.
   
   Thus, I *GUARANTEE* myself at least 3 cycles:
   • Low CAPACITY because of the initial DISCHARGE.
   • First *REAL* test of CAPACITY.
   • Possibly *FINAL* test of CAPACITY, if it doesn't exceed 'b' (#2).
   .
5. • Please refer back to #3.
     .
   • • The mAh on NEW Duraloops / Eneloops will be ~2000mAh. If you get ~1800-2100mAh, don't fret.
     • The VDC on a La Crosse will probably hit ~1.53VDC at -DeltaV termination. (You can SEARCH the Archives for more 'estimates')

Thanks for the help and links. They are discharging again and read about 1950 maH.

Re: I my new La Crosse BC-700 working properly?

Hi, I have some similar questions about the refresh mode...
Mine is a cd-1000 from amazon.ca, version 37. refreshing at 500/1000mA current

right now it is on its second discharge, but the capacity display is showing a constant mAh value, and it's probably the capacity of the first discharge. (eg: slot 1: discharge/refresh 1362 mAh/0.19h; 1.30V)

If I understand correctly, every discharge, the capacity display should show the amount of the on-going discharge, so it should be going upwards from 0 mAh. the only slightly assuring thing is that now at 1.33h, the voltage is 1.23V.

btw, per the manual, it should show the "capacity determined in the last time discharging" during the next charging process.

is my charger faulty?
