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.

User questions & answers

Question:	My 4 batteries were losing charge so I put them in the charger. The lights are green. Do they have to be completely dead for them to recharge
Answer:	If your batteries are a few years old (or have been over-charged routinely), they may have developed high internal resistance. When used in a photoflash unit, for example, they will give very slow refresh time since the terminal voltage is lower under load. But when you put them in a charger, the terminal voltage becomes higher due to charging current. So the EBL charger (which is not very smart) considers those batteries as fully charged, even through they are not.You should get some better quality rechargeable batteries (such as Panasonic eneloop) to use in your photoflash unit.
Question:	Can you charge different mAh batteries at a time? Lets say I have four 2000mAH and four 2300mAH batteries, do I have to charge these separately
Answer:	I would think they can be charged together. The mAh value simply is an indication of the length of time the battery will operate. It has nothing to do with out put current or voltage. The 2300 may take a bit longer to charge than the 2000, but I cannot say for sure that would be the case. I would put the 2000's together and the 2300's together. Don't put one size next to the other size.
Question:	How long does it take to fully charge batteries
Answer:	Charge time is determined by the capacity of the batteries divided by charging current. The charging current of EBL 808A is very low at 200mA. So to recharge a pair of 2800mAh batteries at 200mA will take at least 14 hours.
Question:	can it charge uneven amount of batteries (1, 3, 5...)? Can you recommend any charger to charge 3 batteries? AA or AAA
Answer:	This charger can only charge in pairs, but we do have some other chargers that can charge uneven amount of batteries, here are the links: 1. http://www.amazon.com/gp/product/B00KBQ7U102. http://www.amazon.com/EBL-Battery-Rechargeable-Batteries-Released/dp/B00OT7HSBO3. http://www.amazon.com/EBL%C2%AE-Universal-Discharger-Rechargeable-Batteries/dp/B00IHT2AUE/ref=sr_1_11?s=hpc&ie=UTF8&qid=1399165294&sr=1-11&keywordsYou can choose your favorite ,may it help you!

User questions & answers

Question:	can you charge other brand batteries in this charger
Answer:	I have this charger and it will not charge any brand battery except the Eneloop battery. Do not Buy it for other batteries, it will not work. I bought it based on reviews and that I have about 20 NiMH batteries of various brands. Not one of the 20 would charge on this charger.
Question:	Must you charge 4 batteries at a time OR can you charge, say 2 with 2 open slots
Answer:	The Panasonic BQ-CC17 can recharge 1, 2, 3 or 4 AA/AAA cells at once. You don't need to charge in pairs like in the case of old MQN06 charger.
Question:	i just received the charger and i do not see any indicator lights on mine. anybody
Answer:	Just to update this - the chargers shipping now have hidden lights (unlike the product picture). To see them charger must be plugged in with batteries in place. NOTE: To clarify the paper comment - the batteries are shipped in the charger in the charging position. Before first use, remove all four batteries and you will find a small piece of cardboard paper at the top covering the positive charging contacts. This paper is to be discarded. Put the batteries back in position, plug in charger to working circuit and you will then see the now hidden lights under the white plastic "skin" below each battery. This is still true as of 11/2018.
Question:	What is the difference between the Panasonic K-KJ17KHCA4A Eneloop Pro vs the Panasonic K-KJ17MCA4BA? Which is a better choice to buy
Answer:	The pro cells hold about 25% more capacity under use before you have to charge it. That translates to longer run times for things like hiking GPS and high powered flashlights and wireless microphones in constant use. The trade off is that the pro cells don't retain a charge when stored which is good if you normally plan to drain the battery within a few days of charging it. In a TV or DVD remote control, the pro cells would have to be charged at least once every several months, where the regular cells will last for years without charging in remote controls that are not used daily. So far, I have never had an Eneloop battery ever leak, where I have had several expensive remote controls and headlamp LED's destroyed by leaking modern alkaline batteries. Modern alkaline batteries will often start leaking while still performing and still many years before the best used date has arrived. Modern warrantees for alkaline batteries only cover the battery that fails to perform, not the expensive device that was destroyed by the leaking alkaline battery. I have had several Duracell batteries start leaking while still unused in the original package stored in a cool dry place (basement) and still have a few years before the best used date has arrived. Today's alkaline batteries are junk. The standard Eneloop battery seems to be the most dependable battery I have ever found. They cost more, but the extra cost is worth it. Other brands of NiMH batteries I use often don't hold a charge in storage. The supposed lower voltage compared to alkaline is not the whole truth. Under extreme low power loads, alkaline battery voltage is higher, but under higher loads like cameras and flashlights, the alkaline battery voltage drops lower than NiMH battery within a second of the time the load is applied and then goes back up to resting voltage after the load is turned off. After an alkaline battery looses around 20% of its original charge, it is performing worse than a rechargeable NiMH battery and many devices like cameras can't take that drop in voltage.

User questions & answers

Question:	Wanted to find out about warranty my batteries can charge for 2-3 days and base is still red what can I do
Answer:	1.2 volt, like all standard AA, AAA, C, or D rechargeable batteries that I am aware of. (btw, these batteries are great. I have bought the EBL AA and AAA packs several times.)
Question:	Are these batteries charged and ready to go out of the box, or should i charge them first
Answer:	No it does not. This is very misleading; after reading these comments and seeing pictures in reviews it seems the unit used to have an actual 115/120V plug on the back to just plug it in to a receptacle - which is what I wanted. Instead it now seems to come with a Micro USB cable & connection on the top requiring separate power (5V @ 1000mA). This information isn't in the description or specs at all.
Question:	It doesn’t charge
Answer:	You can charge 1, 2, 3 or 4 at a time.It makes no difference as each battery is charged separately.There's 4 "little brains" inside. Each one dedicated to a single battery.There is an indicator light for each battery. In 3-4 years, as batteries age, some will take longer to charge and you'll know which one is going bad.
Question:	Does this charger charge lithium batteries
Answer:	False. I have slso used Amazon batteries

Question:	How long does it take to charge batteries
Answer:	this will depend on the capacity of the battery and the state of charge it currently has.
Question:	Will it charge any brand of battery
Answer:	I have several brands of rechargeable AA and its works for all of them. They will not all recharge by the same time. I try to keep the same type together.
Question:	what does charge error mean? It is not addressed in the instructions
Answer:	It mean that the charger has analyzed the voltage change between charging and discharging. It is constantly performing tests on the batteries. It has decided that the battery is not holding a charge as well as it expected the battery to do. Unfortunately, this charger is too sensitive and gives up on batteries that still have a lot of useful life left in them. You can't use this to charge batteries that are more than a couple of years old or batteries made by different manufacturers. I don't think there is a way to defeat the error message and still charge the batteries.
