Universal Smart Battery Charger Mark II For AA AAA C D 9V Li-on Ni-MH Ni-Cd Rechargeable Household Batteries With USB Charger Cell Port

I previously had an Energizer branded battery charger that was pretty versatile and was able to charge various size batteries. Eventually the display died and so now I can't tell if the batteries charge or not. When looking for a new charger I came across this one with its claim to be able to even charge alkaline batteries. My curiosity was piqued and I ordered Maximal. So far I have been impressed.This universal charger has been able to charge everything I have thrown at it, including alkalines. We have a little boy so there are a number of battery operated toys and such that we need to change out the batteries for more often than what we are used to with other device. This makes having a charger like this a necessary tool. The charger has a setting switch to set it to charge Ni-Cd, Ni-MH or Alkaline batteries. It's important to make sure you get this switched properly as you will either get an insufficient charge some other error. The LCD display will show when a battery is in place and charging, when it's complete, and if the battery is bad and can no longer be charges. The LCD screen is not backlit, which is one drawback as you will need sufficient room lighting to read it. Good news there is each battery slot has a light to tell you if the battery is charging and when it's completed.When comparing this charger with the Energizer brand I previous I do notice that the batteries charge faster. I also notice less misfires where you have to reinsert the battery because the charger didn't pick it up right the first time. MaximalPower has four slots that adjust to the size of the battery from the large D's to AAA's. There is even a spot to charge 9 volt batteries (a useful addition for keeping those fire alarm batteries charged). The charger itself is always on, and the only way to turn it off is to unplug it. Another small negative detail all things considered.The batteries work well, especially the alkalines. Others have mentioned the charge on the alkaline batteries seems less, and I may agree. However I haven't noticed a significant difference, at least between the charge longevity of other rechargeable batteries. Yes it's not the same as your fresh copper-top, but it's still as good as everything else you put in this charger.Maximal Power met my expectations for a capable and convenient way to recharge my batteries, and impressed with charging options I never thought were possible. You are going to want this charger if you have any alkalines lying around.

Bought this to recharge batteries and know I will benefiting from this purchase. Already use it four times to recharge 9 volts, AA and AAA batteries. Just like an other product. If you have something charging like this please do not use it when your not home and also would rather recommend having it somewhere where you can hear it in case some of your batteries do fail from leaking or bursting. But so far this has been an excellent product and would still recommend this to others if needed to.

After reading all the great reviews I decided to purchase this charger back in May. I have used the charger for both Alkaline and Ni-MH batteries. It seriously charged all of my old alkaline batteries from AAA to D that I had set aside to recycle! It works great on the Ni-MH batteries (I’m using the Tenergy Centura brand)! Overall, I was very impressed! The product did exactly what it’s was described to do! Also, looking at other charges this was a great price and a very versatile and user friendly charger! So, it seemed to be a five star product, but I’ve ran into a problem.I recently noticed that a majority of the alkaline batteries (all Energizer) had either started leaking, corroding, and/or expanding in my battery case, some to the point that it was difficult to remove them from the case. They ranged from AAA to D batteries; each size had at least a few batteries that became damaged after only one charge. Not a big deal since these were batteries I planned on disposing of, but I had expected better results after reading the reviews and description of this product. I read through the instructions and followed the recharge instructions for the standard alkaline batteries. I admit that not all of the batteries may have been completely drained as stated in the instructions. I’m not sure if this is the reason for my results.Either way I will continue to use this charger for my rechargeable batteries but I’m a little weary of reusing alkaline batteries due to my previous results. If any other users have any suggestions on getting better results with the alkaline batteries please share them. Thank you!
