User questions & answers

Question:	does it discharge batteries
Answer:	The EBL808U does not discharge batteries. There are other models that have a “refresh” function that will fully discharge batteries.
Question:	Is it dual voltage
Answer:	No it's 120v only sorry but they are amazing
Question:	Is there a distinction between the two usb ports? one is listed as 2.1a and the other 1.0a. will this effect their use
Answer:	Yes. 1.0A is a 1.0 Amp outlet, and the other is 2.1 Amps. Larger devices, such as late model phones and tablets will charge much faster at 2.1 Amps, but small devices, like bluetooth headsets & watches can easily charge at 1.0 Amp.
Question:	v or 1.5v
Answer:	Advertising mumbo. The 1.5 alkaline batteries are only 1.5 at the very beginning and go downhill just like a ski slope, ending around .08 and dead. The “1.2” is pretty honest. The discharge curve of rechargeables stays above 1.2 for much longer.

User questions & answers

Question:	Do both triple A and double A batteries come with the charger
Answer:	The Sanyo/Panasonic eneloop cells can be recharged in any good-quality charger designed for NiMH batteries.For best battery lifespan, choose a 'smart' charger that has a charge time between 2 and 5 hours.Avoid slow, timer-based dumb charger that will over-charge your batteries, and 'ultra-fast' 30-minute chargers that will over-heat your batteries.
Question:	This listing says: “for free adapter, please go to promotion” - there is no promotion tab. send me a 2v adapter as this listing states
Answer:	I use & prefer the Maha C9000 charger. It charges, conditions your batteries and displays all the info you need to tell you the state of any AA & AAA battery.
Question:	Can this recharge any brand of rechargeable battery such as energizer, Amazon, or Duracell
Answer:	The enloop charger will work with NiCads, NiMh, and some of the newer AA sized Li ion rechargeable batteries as long as the resting battery voltage is 1.25VDC. Do not drain your batteries past .9 volts, as this will reduce the number of recharge cycles possible in the battery. NEVER run rechargeable batteries completely flat (0.0 V) because there is a big possibility that you will destroy them.
Question:	How come the red light is flashing when I charge 5 or above AA batteries? 4 batteries are fine (red light no flashing
Answer:	Some newer solar lights use lithium batteries, ( 3.7 volts ). If your present batteries are 1.2 volt NiMH ( Nickle Metal Hydride ) or 1.2 volt NiCd ( Nickle-Cadmium ) these are OK ( if they fit ). My various new & old solar lamps use AA, AAA or half-length batteries. Best one recharges my AA's for flashlights. I also recharge disposable alkaline AA's, believing it's Very low charging rate will not explode them.

User questions & answers

Question:	Pansanic cc-75 charger will be suitable for those battaries
Answer:	Not familiar with that charger, but if it works on Ni-MH AA batteries, yes.
Question:	Are these lithium-ion
Answer:	No, these batteries are Ni-MH rechargeables battery not lithium-ion
Question:	Where are these batteries manufactured
Answer:	These batteries are produced in China. Battery cells from Japan
Question:	is it ok to use 2800mah NiMH batteries in my home patrol 2 scanner
Answer:	You really do not need to worry about milliamp-hours (mah). Your appliance is going to draw what whatever current it needs. It's the voltage that needs to be within the acceptable range of what the device calls for. These batteries are 1.2 volts each. So multiply 1.2 by the number of batteries required and that will give you total voltage. Then look at the manual and see if that voltage is within the acceptable voltage input for the device.

User questions & answers

Question:	are this AA batteries fatter then Alkaline batteries ? i use eneloop lite where i cant use regular eneloops due to size restrictions
Answer:	Amazon keeps switching up the game to keep us guessing. As of 7/20/2019, the black label/green top batteries are definitely made in CHINA not japan (just received some, and I'm sending them back). None of Amazon's descriptions state whether or not either the black, silver, or white batteries are made, so I would assume that they are all Chinese at this point, which implies all of the manufacturing, quality, and supply chain issues Chinese batteries are famous for at this point. Do yourself a favor and spend a few extra dollars for eneloop or energizer, etc.
Question:	can i use my eastshine s2 charger? or must use your charger
Answer:	Updated on April 4, 2015To clarify, there are now three different versions of AmazonBasic rechargeable NiMH batteries:- The original AmazonBasics batteries came in black wrappers. They are made in China and have the capacity rating of 2000mAh. They are NOT as good as Sanyo eneloop batteries.ASIN:B0030T1NEA AmazonBasics AA NiMH Pre-Charged Rechargeable Batteries- The second version of AmazonBasics batteries came in white wrappers. They are made in Japan and also have the capacity rating of 2000mAh. They are (according to me) rebranded 2nd-gen Sanyo eneloop, so you can expect at least 1500 cycles lifespan.ASIN:B00CWNMV4G AmazonBasics Pre-Charged Rechargeable Batteries- The third version is also black but called 'high-capacity'. They are (according to me) rebranded Sanyo XX. They are rated 2400mAh, but actual capacity is around 2550mAh, just like Sanyo XX. The rated lifespan of the XX is only 500 cycles.ASIN:B00HZV9TGS AmazonBasics High-Capacity Pre-Charged Rechargeable Batteries

User questions & answers

Question:	What is the difference between the "Black" and the "White" AmazonBasics rechargeable batteries
Answer:	I purchased the white label 1900mAh batteries and black labeled 2000mAh batteries several years ago. Contrary to other's comments, the white batteries are still charging up to full capacity, and the black batteries have all lost significant capacity. White labels say "made in japan" and black labels "made in china". Mfg Date of black batteries is AUG2014, and white batteries have "201409" imprinted. These have all been charged in the same MH-C9000 WizardOne from the beginning.
Question:	will it be hot if charge it at 1a with eastshine s2 charger
Answer:	1a would be .5 C with these 2000mah cells.. I checked the IR of these cells and with my Turbo Matched 30 from Competition Electronics (these are a 1500 dollar cell matching system that we professional RC on road and off road car and truck guys used to match cells. Very important and HIGH TECH for the time system. Was made for Nicd cells but worked equally well on Nimh cells when they came out) and matched them to get well matched pairs for practice cells for Mod Mini Z cars and boats.. I used Enloop cells for race days and practice with these.. these cells give a solid 2050 to 2100mah handle, will give me long run times and with cells matched with a 6 amp discharge will give me a avg voltage of about 1.02v per cell over 25 minutes, my well massaged Eneloop 2kMah cells i match at 8.5 amps they give me a avg May of 1980 to 2020mah and will hold a avg Voltage of 1.06V per cell at 8.5 amp load over 25 minutes. Point is these cells are a very good value, even in high load usage these cells stand up a lot better then similarly priced Nimhs from other brands.. these cells offer 85% the performance of Eneloop at less then half the cost.. the cells hold up well until about 200 cycles then they deff start to have noticablly lower avg voltage over time at the same discharge curve.. but that's in higher load apps then most people will be using them for.. I charge these cells at .75C or 1.5 amps, at 1.5 amps the cells are slightly warm off the charger and that's how I want them, slightly warm when ready to run as the IR will be lower with a warm cell over a room temp one giving me less voltage sag as the cell warms up under load... These cells will be slightly above ambient temp of charged at .5C or 1 amp, the warmth will start to happen once the cell reaches about 90^% full charge and progressively get warmer until peak charge.. at .75C charge or 1.5 amps you will notice the cells are a fair bit warmer then ambient temp and this has it's use for high load apps like my Mini Z's and some times I'll even charge them at 1C or 2 amps.. that will make for a fairly hot pack BUT will give me the highest voltage under load for the first 25 to 30% of the charge... but will ABSOLUTELY shorten the cells life and I would not recommend doing that UNLESS you know what you are doing to the cell and understand the cells life will be cut by good bit.. meaning if I get 200 really good cycles on a set of cells when charging them at .75C or 1.5 amps, moving to a 1C or 2 amp charge will know it's really good cycles life down to 100 to 125... but you will have less voltage sag/higher voltage under load taking the very warm cells off the charger and straight to using them then if you was to charge them at a lower rate and have cooler cells... Charge at 1 amp and you will be happy with these cells .5C and under will give you the longest cell life for sure..

User questions & answers

Question:	Can you use the charger on the Energizer Power Plus NiMH AA Rechargeable Batteries rated at 2300 mAh
Answer:	You could if it actually worked. This charger stopped working within a month. I returned mine. Also you might want to consider more battery slots. 4 seems ok at first but now I got 1 with 8 slots and I think it's too small.
Question:	Does this charger only charge in pairs? Is it possible to charge 1 cell (at a time) with this charger
Answer:	I have owned this. The universal charger WILL charge batteries individually. There are 4 charging 'points' and you can choose to put one small battery (AA or AAA) in one point. Of course, you can also put two small batteries in each point to get the full 8-at-a-time figure. This also only applies to the small batteries. Cs and Ds are charged individually in each point, so their max is only 4 at a time total.
Question:	Can this charge aa and aaa at the same time
Answer:	Yes. AAA on one side and AA on the other. Not on the same side at the same time.
Question:	Can i use Energizer CHRPROWB4 Pro Charger with 240 volts 50 Hz AC input
Answer:	Hi Nikhil Singh, over at the Energizer web site they have some additional information. Look under batteries and then battery chargers. You can download the user manual for this model. The user manual clearly indicates that 240V 50Hz power is OK. The only problem you will have is the plug. The two-prong plug is designed for U.S. outlets. Of course, any plug adapter will solve that problem.Basically, the answer is yes.
