EBLAA Battery 1.5V AA Lithium ion Batteries 3300mWh High Capacity with Micro USB Cable, 2 Hours Quick Charge USB AA Rechargeable Batteries 4 Packs

I bought their older set of rechargeable batteries that had flashing red LEDs. They would last about 7 days on my wireless mouse and then I would have to recharge them, this was no issue. Two of the batteries stopped recharging so I bought another set. After getting the new set they no longer have a red LED they just flash blue which is distracting at times, they don't seem to hold a charge for as long. These new batteries only last around 3 days and all of them have already stopped charging. I will be getting my rechargeable batteries from someone else.Update: The company responded to me and gave a refund after giving me a set of steps to follow. They seemed adamant that the product works well and I could be doing something wrong. I checked the output voltage on my USB line with a volt meter when the charge cycle would start. I realized since the USB extender was so long the current draw was causing the voltage to drop below the required levels to charge properly. Now I just charge them directly off a powered HUB and all the new batteries seem to charge fully now. The older ones have just died from age at this point so overall the batteries are holding up.

They work as intended, came with a really cool double charging cable so you can charge the pair at the same time.Theyve lasted in my wii remotes for a long time, i think theyre still on the first charge after like 2 months.The only thing i think that would be better is if it was a type C connection instead of that dreadful micro usb.

First off, power and current are two different things. The electric companies charge you for the power, not the amperage. These will provide a relatively stable voltage throughout their discharge cycle. Some batteries are rated in mAh, some are rated in mWh (milli Watt hour). My favorite eneloop pro batteries are rated at 2500 mAh but only provide 3000 mWh of energy, enough of that.If your device does not mind the supply voltage dropping over time (like a flashlight beam getting weaker), then you do not need these. If you want a stable voltage, then these are good. I have read reviews where people say these do not last as long as NiMh. Guess what? The NiMh have equal or less power. The NiMh just lower the voltage as they discharge, and seem to last longer, at greatly reduced output.It is confusing, but for things like lights and radios that work better with a steady voltage, these are good.The downside is that when these are done, they just quit. 1.5V until the end, so keep some handy.

Warning: Those batteries output 1.5V as expected, but if they are low and you want to recharge them while powering the device that they are plugged in, it's not unreasonable to think you can plug them into a USB battery pack while they are being used in a device.I did that, and the batteries started outputting 5V which fried the GPS they were plugged into.I'm obviously not happy.I figured that out by using a volt meter after the fact and seeing the battery terminal voltage change from 1.5V to 5V after I plugged them into USBApart from this issue that will hopefully not be a problem for most:I tested 4 kinds of Lithium AA batteries, and I'm putting the test results below.There were the 2nd best (new Xtar are the best, EBL is 2nd best since it has the same capacity but without custom charger)New Xtar: Rating: 4.15Wh, Charge: 5.5Wh, 3.45Wh Usable discharge at 1Ahttps://www.amazon.com/gp/product/B0CF8ZNZ33/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1Summary:* This is the only lithium battery that drops its voltage to 1.1V to give you a low voltage warning. Other batteries I tested just die with no warning. That alone is a reason to select it. I tested it with my garmin GPS and it gave me 2H of low battery warning before finally dying. Very nice!* It is also the battery that gave me the most actual discharge capacity* Seller is not lying about cell capacity (thank you) which of course is higher than actual usable energy due to conversion losses* New charger is unfortunately bigger than the old one and drops the USB-A output feature to use your batteries as an emergency USB charger* Verdict: this is the best battery I tested and what you should buy as long as you don't need a built in charger like EBLOld Xtar: Rating: 3.3Wh, Charge: 5.3Wh, 2.7Wh Usable discharge at 1Ahttps://www.amazon.com/gp/product/B09NLVJDY6Summary:* This is the older Xtar battery. It had best in class capacity until the newer one that came out with added low voltage warning. There is no good reason to buy this battery anymore, get the new one.* Its capacity is equivalent ot the EBL battery with built in USB charging, so the EBL is more versatile* The charger is very compact and can act as a USB power source, that's a nice feature.* 10.6Wh to charge 2 batteries, or 5.3Wh charge per batteryEBL 3.3Wh rating, Charge: 4.3Wh, 2.7Wh usable discharge at 1Ahttps://www.amazon.com/gp/product/B08RZ5NDMMSummary:* There is no low voltage warning, but the battery capacity is actually equivalent to the old Xtar despite the space lost to the built in charger. The new Xtars last longer than the EBL though.* Interestingly EBLs need less energy to charge than Xtar for the same output capacity, they are more efficient* Big warning: if you try to charge the batteries via USB while they are in use, they are going to output 5V instead of 1.5V. This is unexpected and fried one of my GPSes. You cannot charge them while they are being used.Deleepow 3.4Wh rating, 3.8Wh charge, 2.4Wh usable discharge at 1Ahttps://www.amazon.com/gp/product/B09NLXQRP3Summary:* These battery are not for sale anymore, and they were the least performing amongst the ones I tested.* The 3.4Wh cell capacity is probably untrue with the charge and discharge numbers I got

Blink turned out to be a bit of a pain requiring higher sustained voltage lithium ions which are very expensive. So finding out these rechargeables work so great, very happy thus far! Not all rechargeables qualify, so I'm glad we chose these.

I like the Lithium ION batteries because they have the full voltage of 1.5 volts, just like Alkaline does. There are still lots of devices that don't work properly or at all when using NiMh batteries because of their lower voltage of 1.2 volts.I prefer Lithium ION in these cases so that I can be more environment friendly.I also like that these batteries come with USB charging cable and are directly charged instead of having to get a separate device to charge this type of battery. Note that chargers that work with NiMh typically do not work for Lithium ION.The only downside is that Lithium ION batteries put out the full 1.5 volts until the very end of their charge, unlike Alkaline in which it starts dropping off as it nears full depletion. Essentially what this means is that with Lithium ION you most likely will not get low battery warnings from your device - when the battery is fully depleted the device will simply stop working suddenly. But this is not a knock on this manufacturer because to my knowledge ALL Lithium ION batteries work the same way.I highly recommend these batteries unless you have a device in which you really must get low battery warnings.

I recently purchased the EBL 4 Pack USB Rechargeable AA Lithium Batteries to use with my Blink doorbell, and they have exceeded my expectations. These batteries are easy to recharge using the included USB cable, making them incredibly convenient. They hold a charge well and provide consistent power to my doorbell, ensuring it operates smoothly. The fact that they are lithium batteries means they last longer than traditional rechargeable batteries. Overall, I'm very satisfied with this purchase and would recommend these batteries to anyone looking for a reliable and eco-friendly power solution for their devices.

Great performance… very pleased.

This is the second set of these that I’ve ordered. The first ones have done very well powering my shaver. I am testing these to see how well they do in other applications.

Installed these in two Blink cameras - charged okay and liked thefact that the charging is built in to the battery - came with chargingcable. Will see how long they last before needing a recharge.

The first time I needed to recharge these batteries it all went fine. But now when I try to charge them, the device I put them in says low battery still. I'm using the cords provided with a good name brand charger so I don't know what's going on.But for the price of these batteries i expected them to last.All of the other EBL rechargeable batteries I've bought have been great.
