Dazzling LCD Percentage Fast Charger

If you need a lot of CR123a sized batteries, this is definitely the kit to get. This Battcruize 8-pack comes with a charger (with built in USB a plug), USB C charge cable, user manual, and an 8-pack of CR123a batteries in a nice carrying case. The labeling seems to be incorrect on the batteries, as the box says these are 800mAh...but the battery label shows 800mWh...which would mean 800mWh/(3.7V) = 216mAh...which would be a nearly useless capacity battery.I fully dicharged one of the cells in a flashlight and charged it to 100% with a capacity of 1081mAh (=5448mWh). Which is about 30% higher than the stated capacity. It also shows fully charged at nearly 4.2V, which is correct for a 1S Li-ion cell. The charger is also very nice. It's capable of charging four cells at the same time and has both a built in USB A cable and a USB C port so you can plug it into any other charging cable. It also shows the charging percentage of each cell (most likely base on voltage). This is definitely a well thought out kit with high quality batteries. Highly recommended!

I run weapon lights and those disposable lithium batteries can get expensive real quick. I saw this rechargeable solution and decided to give it a try and I'm glad I did. With disposable batteries, you really never know where they're at as far as percentage of a charge goes. With these, after use, you just change out your batteries with 100% charged batteries and you know you're good all the time. I really like that concept. All my batteries came about 86% charged.. all the same voltage according to my battery meter that shows voltage. I threw them on the charger and the nice LCD display showed one at 96% for some reason. They all charged up to 100% and showed the same voltage (4.66 volts) on my battery voltage meter. As far as longevity goes, only time will tell. The charger is really nice looking and feels like quality, so I am imagining that the batteries themselves are good as well. When you factor in the cost of these batteries all the time, I'd say this is a good investment. Not only will you save money, but you'll also keep used batteries out of the landfill... Better for the planet.I will update my review if and when I have issues. But I anticipate these to last. It all just feels like decent quality.

I really like this little charger. It seems to be well made, and the digital read-out is really valuable. It is great to see an accurate tracking of the charge on each separate battery channel. in my particular use, these batteries are important for emergency preparation as I use them in one of my best flashlights. And of particular importance is the fact these rechargeables hold their charge for a very long time, so they can be packed away, and you can still rely on them way down the road to be ready to use should you need them. Lastly, of course you have good money-saving potential since you can recharge these over and over and avoid buying disposables constantly. A really nice recommended set!

I'm giving this charger and batteries 5 stars even though it didn't work for my use case...but that is no fault of the batteries and charger. More on that later.Okay first of all, great value, for less than $40 you get 8 CR123a batteries and a charger with individual display for each battery.Normally an 8 pack of rechargeable CR123a 800mWh will cost about $20-30. I think this pack would have been worth it with just 4 batteries...the fact that it comes with 8 is pretty generous I think.It also came with a USB C cable. I plugged the USB C cable in and as I started putting some batteries in, I saw the built in USB cable...built right into the body of the charger. I totally forgot that it had a built in USB cable.Im not sure if it charges at a different speed or is just there as an option. But pretty cool that its built in and you dont have to use a separate cable if you don't want to.The supplied batteries were charged between 70-90%, I plugged the charger in and left it, I think within 30 mins or so they were all at 100%.The Screen clearly indicates which battery is at what percentage.It also has a cool function if you accidentally place the battery in backward, the icon for that "channel" will flash, to let you know that you put it in wrong.It did not work for me because the product I was using it in needed more than the 800mWh that these provide, they need the real 1500mWh lithium power. The product clearly tells me "rechargeable is not recommended". Well I thought I'd give it a try anyhow, and they were right, the motor in the product needed more power and would not turn all the way. That's my fault.I think this is a great compact charger, and if I can find higher capacity batteries, I'll buy them and use this charger.I think these batteries are more suited for cameras, flashlights, keypads...but not something that has a motor and the manual clearly states "do not use rechargeables"...my bad.As of this review there is a hefty coupon, its a steal of a price if coupon is applied.

Abut two years ago I purchased a flashlight thinking it had lithium batteries 18650 but it had cr123 or cr17345 and I just laid it aside . I saw this and could not let it go, so I received them yesterday they had about 85% charge I put them in the charger and in about 1/2 hour they were full. I didn't time it. I played with the light off and on last night and it held charge and with 4 refills should never have a problem with longevity. Functions as you would expect. They at full price seem somewhat high but they aren't outrageous if you need them
