  Just want to share... for Eneloops and other LSD type NiMH batteries I highly recommend this charger:
  
  POWEREX MH-C9000 WizardOne
  <click here for link>
  
  
  
  It was able to revive almost all of my old NiCD and NiMH batteries that were damaged by fast chargers and other smart chargers I have bought through the years. It is a bit expensive though but a worthwhile investment especially if you have invested in a lot of high capacity batteries like Eneloop XX, Eneloop Pro, or Sanyo Harmolattice :-)

  or alternatively you can revive using a dumb charger

  How do you revive LSD batts with high internal resistance using a dumb charger?

• roceanoz on May 23, 2013 08:53 AM

  I guess... plug in the dumb charger and put the battery in the charger. Wait for say, 10 to 20 minutes. Then transfer to your normal smart charger.

  Well sa experience ko naman, I had a set of Sanyo 2700mAh NiMH batteries na mabilis mag-drain at parang hindi siya na-fu-fully charged. Yung ginagamit ko na charger at the time yung smart charger bundled with the Sanyo batteries (4 slot charger with refresh function). So ginawa ko ni break-in ko sila sa Powerex C9000 for about 3-4 cycles, ayun bumalik sila sa dating performance :-)
  
  I read before that the Lacrosse BC-900 charger can even revive severely damaged NiMH batteries na hindi kaya ni Powerex C-9000, but I think there are certain models of BC-900 that are prone to overheating / melting :-|

• roceanoz on May 25, 2013 12:26 AM

  We were talking about reviving batteries. Dumb charger can or may revive batteries. YMMV. Whereas for refresh...
  
  Refresh ---> fully charged the battery with any smart charger. Fully drain the battery by using it naturally. Deplete the last remaining juice using say a small flashlight preferably unregulated. Do this for two to three or even four normal cycles/use. After this you may not fully replete the battery again before recharging.
  
  I also do this occasionally with cellphone/camera batteries when performance degrades.
  
  Of course your expensive chargers do all of these better, without the hassle and a lot safer. Buy/Use if you can afford them.

  Finally I was able to read somewhere in the candlepower forums the process of reviving a low performing NiMH batteries using a dumb charger. Unfortunately I lost the link... but I do remember the method since it is similar to the "break-in" function of smart chargers. However it is a time consuming process:
  
  1. Get a slow dumb charger that has a charging rate of 0.1C of the battery you are trying to revive. So if you are reviving an old Eneloop 2000 mAh cell, use a dumb charger with only 200mAh charging rate. To compute the charging rate just multiply the capacity of the battery (2000 mAh) with 0.1 and you should get the desired dumb charging rate.
  
  2. Make sure to normally discharge the battery first then charge it with the dumb charger for 16 hours. It's ok to exceed the 16 hours charging time by an hour or two since the 0.1C charging rate should be low enough that overcharging will not damage the battery.
  
  3. After 16 hours charging, let the battery rest for an hour or more. Then discharge the battery using a low power flashlight. Check the voltage of the battery once in awhile using a voltage tester and make sure it does not go below 0.9 volts when discharging. If the voltage goes way below 0.9 volts (like 0.5 or 0.4) for extended periods it can damage the battery further and reverse polarity might happen.
  
  4. Repeat steps 2-3 until the performance of the battery returns to a usable state. Of course it will not perform like a brand new battery but if you can still get 70% or 80% of the expected capacity of the battery then at least you have salvaged a once unusable battery. Otherwise if the battery damage is too severe then might as well chuck the battery in your wall clock or TV remotes hehe...
  
  I have not tried the above personally, and it is a time consuming process, so I would say "try at your own risk" :-)
  
  @All
  A very good but affordable smart charger is the Sony BCG-34HLD AA/AAA NiMH Charger:

  I have bought Eneloop batteries from waltcor and I can vouch that they are genuine and original Sanyo Eneloop batteries. I'm not sure if they came from Sanyo Philippines though since his supplier might be different.

  i can vouch that it is genuine, i have bought from him multiple times, best of all is the FREE delivery =)

• lotec on May 27, 2013 02:08 PM

  waltcor's are ok.
  
  Also, I don't think there is a Sanyo Philippines. That's why eneloops are very expensive when bought locally from the malls.
