EBL Rechargeable 9V Lithium Batteries 5400mWh 9 Volt Li-Ion Batteries Long-Lasting with USB Charging Cable, 2-Pack

Too lazy to find your battery charger? Built-IN BABY!!! Supply the UBC-C and the rest is free. (assuming my assumptions are valid, which THEY ARE ate least 10 % of the time)

The only thing is how long it lasts

The ebl rechargeable batteries have always been great for me, I've been using them many years.

Won't go through all the details. Let's just say that, through a lifetime of injuries of many types, pain is a constant companion. Neurosurgeons cringe at my MRI's. Even the spinal implant didn't help, but tens units DO. Thing is, they eat batteries. Eat them, and eat them, and eat them. I can use 2 9v's in a day. Don't ask me why I waited so long, but I'm *really* glad I found these. They hold a charge well under a heavy load, deliver what I need for hours, recharge quickly. If I'm out and around, I'll keep one running and one in my pocket. When I get home, I can use the charging cord to charge both at once. Get some.

I have 4 Smoke Detectors in my house and I got tired of constantly buying new Name-Brand or Dollar Store 9 Volt batteries! So I bought these EBL USB Rechargeable 9 Volt Lithium Batteries and they are great! When my Smoke Detectors begin to beep, because the batteries are low, I take out the 9 Volt EBL Rechargeable Batteries and charge them. They take about 30 minutes to charge, which I do about every 3 to 4 months! For those of you who haven't noticed! The really great thing about these batteries is that they don't need a charger or charging station, which you can never find when you need it! Just plug the included USB Cable directly to the battery and the other end to your wall outlet, personal computer or other USB devices!

when charging ANY RECHARGEABLE BATTERIES THE KEY TO MAKING IT RIGHT THE = the CHARGER .the smaller and longer time it takes for charging the rechargable batteries the BETTER!. i use either the 1 amp charger, or the 2.1 amp charger , nothing stronger then that, !. the 1 amp is best for charging over night, and the 2.1 is for a 8 hr= full charge. charging with a 3.0 ,3.5 is ok , but thats why your knocking down on this brand EBL? EBL is the leader in the recharging batteries on the market. i use only EBL . i give it a 5 plus rating.

First, about the "5400mWh". Oddly, this battery is measured in miliwatts... This means that if converted from watts to amperes (5400/9=600). So these batteries are actually 600mAh. While not a spectacular capacity, It is a high capacity still comparing to disposables or NiMh batteries which are more of a 200mAh. So the value for the money is very good. The integrated charger is a very convenient feature and works well. Also, the weight is a lot less than conventional batteries. I am giving this product 4 stars because while the packaging is labeled with a picture of electric guitar, these batteries do not work in my particular application. So there is a chance that these batteries will work great in you instrument, however, there is also a chance that they will not. Now about my specific application. I bought these to put in my Peavey Grind Bass Guitar modified with VFL4 active pickups (those who cares, would know). Returning because of the hissing noise the guitar outputs while with these batteries. Comparing to regular disposable batteries, the same bass has no obvious hissing noise at all, unfortunately with these, fully charged, EBL Orange/Black 5400mWh ( with integrated charger), the noise is unacceptable. The seller was gracious enough, as a replacement, to offer me similar EBL batteries that are white/blue and labeled as 600mAh. These batteries work exceptionally, with no noise, and have the same capacity and weight. One difference is that the replacement batteries do not have an integrated charger, but rather come with a conventional desktop charger. Perhaps the integrated charger causes the noise. So in case if the Orange/Black batteries with the integrated charger, do not work for you, you can always count on EBL White/Blue ones. I have left the 5 star review on EBL White/Blue batteries page.

…for some reason when I plug these buggers into my active pickups on my noodle hammer, aka bass guitar, it makes a high pitched squeely feedback noise that normally doesn't happen. Maybe I need a different kind of battery? I don't know. But they charge well and seem like they'd work for anything else. They feel a lot lighter than regular 9-volt jobs.

Never got the charger cable and I had one battery started melting the outer case of the battery . I never heard back from them

I received in the mail yesterday...they DID NOT come with the charging cord! What good are these batteries if I cannot even charge them! Called Walmart...they "pass the buck" and have me wait for an email from the seller. The sellar wants a picture of the batteries...WHY??? Aday later...STILL NO RESPONSE FROM SELLER! NOT WORTH THE HASSLE!...LOOK ELSWHERE FOR A BETTER DEALER!
