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.
