EBL Rechargeable 9V Lithium Batteries, 5400mWh USB 9 Volt Li-ion Batteries Long-Lasting(2 Pack)

I purchased these to use in all of my smoke detectors in the house because I got tired of buying 9 volt batteries over and over again! And they work like a charm!I just hope I remember to get them when I move out of my apartment 🤣🤣🤣🤣

I love the USB charging system.I use these batteries every day for several hours at a time in order to run a 9v pump. I am amazed how long these batteries last before I need to switch them out, and the charging time is very fast. I always have a spare and I am never concerned. I'll definitely be getting more of these. Also works great with solar powered charging units.

Highest capacity of any that I could find on Amazon. Most are significantly less. Very light. Have not had issues with it fitting. Only knock is that it uses a USB mini charging port. Would prefer a more standard USB-C port. Also does not seem to be able to be charged via EBCs own drop in battery chargers. Generally EBC batteries seem to last decently long but not nearly as long as a Panasonic or Energizer rechargeable.

No complaints. No more throwing batteries away all the time

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.

As the pictures show, they do not load test 5400 mWh.I followed their instructions. (they have added >60 years old is approved to use):Charged until light changed from red to green (instructions said blue).Discharged @ 0.1 amp. (100 milliamp) to 7.2v; load test resulted in, practically, identical results. 2436mWh. Tester ended test, not battery.Another 2 cycles.This time I used a USB multimeter to watch the charge. The battery will trickle after the light shows a full charge. I unplugged them when the the light changed.The multimeter shows it taking ~5500mWh of charge, but it does not come out.I even tried a 0.01amp pull that lasted overnight and while it did end when the battery shut off (instead of the load tester getting below 7.2v) 3236mWh is the best I've gotten; that was at 0.1 until 7.2v and then 0.05 for just a few more mWh.They are consistent and they have undervote protection.

Good Product and Good Seller

Works as expected. Takes just a little longer to charge. Packaged very well.Would buy again from this seller
