EBL 40Slot Battery Charger for 1/2/3...19/20/21...38/39/40 pcs AA AAA Rechargeable Batteries - Advanced Multiple Battery Charger - Handle Design(Batteries not Included)

Works well. I have had no issues; I have tried a fully filled charging sessions and a few smaller quantity sessions with 100% success. It stores well and is easy to find in the house.

When I first got this I thought it was overkill and wouldn't need it. I have since changed my mind and have it loaded it with all my rechargeable batteries. Now I always have batteries to replace in my various devices in a neat and organized case. I thought that having one charging light to signify charging status for each pair would hamper functionality a little bit, but even if you only had one battery in a paired slot, you would still know if if it's fully charged. Based on my usage this was not that big of an issue as I thought it might be. I do think that if they included that in a future item that would be perfect.

EBL 40 slot AA & AAA battery charger works quickly to charge all 40 batteries. I'm in for another and I recommend this to anyone looking to change to rechargeable batteries.

Works great.

This is a great battery charger when you have a lot of batteries to charge at the same time. I purchased a couple of car emergency/safety kits that have six lights that require 3 AAA batteries each so I needed a larger charger to accommodate charging 36 batteries at the same time. I popped all 36 batteries into the charger right out of their boxes and it took about two hours to fully charge all of them at once. I'll be using this once a month to charge our safety kit lights to keep them fully charged for emergencies. I'm glad I picked this charger up as it works very well. I purchased the EBL 1100mAh AAA batteries. The only thing I don't like about the charger is it only has one light for every two batteries. Because of this, the light will only turn green when both batteries are fully charged. Therefore, you have to wait for both to be fully charged before you can remove either of them from the charger. Other than that, the charger is relatively small and easy to store. Charing the 36 AAA batteries, it didn't produce much heat at all. Overall, it's a decent charger that I'll be using for years to come.

It never worked from the first time I tried it if you plug it in lights up green then red then all leds go dark with it full of batteries. It's too bad it was a great storage and charging idea.

PROS:As a television show producer and director that films a lot of reality-based shows where we are constantly micing subjects with wireless lavalier mics, this battery charger was exactly what we needed. Each of our mics use two AA batteries, as do the receivers. On a given day, we use as many as 20-40 AAA batteries, which all need to be recharged at the end of the day. Until purchasing this unit, we were using multiple smaller units to charge batteries, however, this device allowed us to consolidate the charging of all of the batteries in one place and at one time. Additionally, we tested the batteries after charging and they were all consistent and fully charged.CONS:I have two issues with this charger, which are the reasons I didn't give it 5 stars.1. There doesn't seem to be an indicator light for each of the batteries. Looking at the included pictures you'll notice that there is a single light that represents two batteries. (A and B). When charging batteries on both the A and B side, there is no way to tell when one of the batteries is fully charged. The light will turn green after both batteries are charged. I would like some way of monitoring the batteries individually so that I can removed charged batteries when they are charged and possibly swap them for other batteries that need charging.2. I noticed that, even though all of the batteries in it are fully charged, when I plugged it back into the outlet, the red lights for all of the batteries came on, which indicates that the unit is charging the batteries. Once fully charged the indicator light turns green. Because the batteries were already fully charged prior to me plugging the unit back up, and the indicator light turned red for all of the batteries, it would seem that the unit doesn't have the ability to check the battery power levels, which means that it most likely charges for a set amount of time, regardless of the power level of the battery. I will monitor this, and if this theory of mine changes, I will update this post.

I was so excited to be able to charge 40 batteries at a time. Most charges are 8 or 16. Unfortunately because of the cord design I'm usually only able to charge 20 at a time (which is still a decent amount). The cord splits into to ends. Each end then goes into a half of the charger. The cord ends are finicky. One side is snug and doesn't move around. The other side the slightest movement and it comes out. I tried switching sides, proping one side up, lying it on the floor so that the cord was perfectly straight and nothing really worked. So I just charge 20 at a time. Would love to find a solution to keep the cord from coming out but until.rhen I will just rotate when I'm charging my batteries.
