Rechargeable 9 volt battery

Just found this one. A 9 volt rechareable battery that sustains a real 9 volts during it's cycle. Actually 8.9 - 9.1 volts. Previous 9 volt batteries only have 8.4 volts max, so I don't use them. The one-use 9v are expensive and many are counterfeit with short life, and the voltage drops with use. One caveat, the electronic circuit inside might cause some interference in your receiver, I don't know, but probably not. EBL 5400mWh charges via UBS cable. Says 1200 recharge cycles. Supports over-charging,over-discharge over-voltage, over-current and short circuit protection. Even has 2 year warranty. About $24 for four batteries or you can buy single quantity around $8 each. Recharge time two hours (with 2a charger). NOTE: The latest version is an upgrade to the higher voltage. Older models, just 8.4v so make sure you get the new version. I don't have a link, but search "EBL 5400". I’ve accidentally drained too many new 9v batteries by accidentally leaving them on or by bumping the on/off switch.

I have stop to use 9V batteries, low capacity.
The EBL 5400 is better but not enought. It can gives only 600 mah max....
Maybe is a good choice for multimeters etc....

You're probably right, no good.

But for everyone else, take a look. Says more power than disposable alkaline battery. One guy tested his at 660 mah. I saw anothe rbattery like this one pink in color got 311mah, Duracell alkaline got 580mah. Yes, it depends on how much current you draw.

I agree that it is better than every alkaline 9V and it is rechargeable

.
But i prefer a 18650Li with a small step up inverter and i have about the double capacity...
A quality 18650 will serve u for many years.

Yes, 16850 is the way to go. I bought a battery box for six cells (they also one for four cells). It has step down to 5v but the charger port puts out 8.4v. But I have devices that use 9v battery. I tried a step up and it made a nasty noise on the Tx. That’s why I say the recharge 9v might cause interference. I hope these have shielding.
