- Independent charging channel
- Charging Voltage: 5V
Red Indicator --- Charging
Green Indicator --- Full charged
(The blue light at the positive pole of the battery is up when charging, and goes off when the battery is full)
Red flashing --- Error
----The charger adopts a high-precision IC control system with battery identification and data reading capabilities. If other types of batteries are mistakenly charged, the charger will issue a flashing red light warning message.
Constant voltage output 1.5V Lithium-ion battery is a new generation of battery, so this Kratax charger is only suitable for this new type of battery, not for the traditional 3V-3.7V Li-ion battery.
Constant Voltage Output
Longer life than normal Alkaline batteries and other rechargeable battery.
Stable outputs voltage from 100% to 0% electric capacity, 1.5V constant voltage output at 100mA discharge, providing constant voltage and best performance in high current and voltage device.
Cost-effective
Capacity: 3500mWh / 2333mAh
Charging time than the traditional Ni-MH rechargeable battery saving about half the time. Low self-discharge, is about 0.03% per month, which is less than 1/100 of Ni-MH batteries. The weight is about 19g, is 20% lower than Ni-MH batteries.
More Durable
It is recommended to use Kratax battery and Kratax charger as a set, not to mix with other brands.

1 out if 12 batteries did not have a charge. 10 out if eleven were put in path lights and lasted 1 day. I have emailed shipper with no response. These are garbage. Energizer is great! Just wanted something to recharge. Very disappointed with product and shipper.

So I've purchased around 50 of these over the last year for my business - we use them in wireless mics, clickers, and wireless in-ear monitors. They work well and last a long time however there is something I noticed that is a potential problem - these DO NOT charge like a regular li-ion battery. I purchased some larger smart chargers to charge them and I found that they do not fully charge. I believe this is due to the charging regulator inside the batteries themselves. A typical li-ion charges at 4.2 volts - but these, if you read the fine print, need to be charged at 5 volts. So I can use the larger smart chargers to charge them initially up to roughly 97%, but to get them to 100% charge, I need to put them into the "dumb" chargers that come with the batteries as those run off USB (5 volts). Kind of a pain but still a money saver over alkalines, especially when you consider we'd go thru several hundred alkalines a year prior to moving to these...UPDATE: Just had the 1st casualty. Battery rolled off the table and dropped on the concrete floor (about 3') and the end broke open. It's completely dead. Hopefully it's just a fluke...

I buy most items based on pricepoint. I aint spending my hard earned money on junk. So after checking 100 different products reviews decided to try these. I didnt have high hopes but have been pleasantly surprised on functionality! I use these in my doorbell and outside camara which experience extreme temperature variations (midwest KCMO summers and winters) between 102°F and -2°F with zero issues. Charges last a ridiculous length of time too!

These batteries are great so far. The charging station is neat as well and does a decent job at charging the batteries. These batteries also work for my Blink Outdoor Cameras. They also seem to last a decent amount of time with the cameras (on saver mode) otherwise they do drain pretty quick based on the camera usage. They also seem to work well in other products. It definitely saves you money in the long run than having to purchase disposable batteries over and over again. Now I just need more than 8 for my other devices.

I use these batteries for my blink camera system. It has made it so much less expensive for me recharging these batteries and they last a long time.

I use a Medtronic Insulin Pump that requires AA Lithium batteries, and wanted to test these to see if they would be a good replacement for buying expensive Energizer batteries throughout the year. The pack of 4 these come in ensure that I can have a fully charged backup battery for my insulin pump in my workbag, and by my bed with another one on reserve. Doesn't take long to charge and lasts for approximately 5-6 weeks.

Bought the 4 pack with charger but one of the 4 batteries is faulty.Update: Due to the prompt reply by the seller, it appears the battery does in fact work fine. It just took a few hours longer to charge than the rest. Updated review from 2 stars to 5 stars.I've had one pair in my Xbox controller for 4 days and they still say full battery. Very satisfied with the battery life.

Our kwikset electric lock typical drains our batteries in 3 days. I don't know if they're just old batteries, but it seems do work fine for all of our other needs. However when we tried these batteries it's been over a week and the battery still reads at 100%. I'm not sure on how else to rate a battery other than it's longevity so it's 5/5 for us! Unless.... They break in another week 😬

I ordered these as it said compatible with Blink. So I received it yesterday and charged all 12 batteries- 4 at a time until they were fully charged (green) then I put them in my Blink camera...I can honestly tell you it turned the camera on for 1 minute and then the batteries no longer worked, so I tried another pair and then another, some wouldn't even turn the camera on.i charged again and tried again after a few hours, went through all 12 of them and none of them sustained the charge in any of my cameras. I played around with this useless ans defective products for hours wasting my time. Then I put my original low batteries back in the Blink outdoor camera...and guess what they worked, so clearly this product is flawed. Do not recommend. It's too bad as this would ha e saved me a lot of money from purchasing batteries as my camera usage is quite high and they drain fairly quickly especially in the cold, but honestly don't waste your time. Or give it a try if you want. I will be returning.

I have 5 Blink cameras. I have 20 batteries. I have ran these cameras through all four seasons. There has not been any issues. When I run the batteries down, especially on the high use cameras, I charge them up when I swapBefore I go to swap out again, I top them off in the chargers.The reason I do it this way is because if a high use camera has drained the battery down to complete depletion, I don’t want it sitting at the low charge state, waiting until I need it again and then the charger may not charge it due to too low of voltage level. It could go into the danger zone of too low-voltage and never recharge again. I haven’t had this issue with these batteries, but I have with my power tool batteries and vape batteries.So back to the cameras, the batteries, (AA) work well. I haven’t used them in other devices, but I am planning on using them in a smart lock.They saved me a ton of money by not having to buy disposables. When the first camera reports battery failure, I replace all the cameras batteries. I wish the cameras report an actual battery life remaining, but I would say they last at least a month and a half if not longer depending on usage.They charge very fast with no issues.

I have about 20 of these now and none have failed. I use them mostly in audio devices (wireless microphones, portable recorders, and mixers, etc.) They clearly have much more power than NiMH rechargeables, and because they deliver 1.5V instead of the 1.2V you get from other rechargeables, some devices work considerably better (shavers, portable LED lights, etc.) The only real downside is that because these cells have their own internal voltage regulator for a constant 1.5V, you never know how much charge remains. If your device shows the battery level, it will always show full until the charge is completely gone. Also, note that any rechargeable AA or AAA Li-Ion cell requires a charger that dows 1.5V. You should not try to charge them on a charger meant for NiMH.
