Any good 9V rechargeable batteries out there?

When it comes to rechargeable household batteries, I say go with eneloop batteries, can't go wrong.

Unfortunately, eneloop doesn't make 9V batteries.

About about two years, I got Rayovac low discharge 9V batteries from Menards (11% off sale). But now some of them already hardly keep a charge.

So, off to Amazon I went looking. Bought one brand's but those batteries don't even fit (a bit too long) in my charger.

Also, how about the Li-ion type that recharges via USB? I own some AA size of these type of recharages and they work great. But don't see any 9V of that brand.

Any size restrictions?

E.g. if I could I'd cobble up a 9V battery pack via 6-AA batteries in a holder.

Has to be a standard size 9v battery.. Nothing funky in size.
