Expensive but worth it
I hate 9v batteries. They are expensive and not very efficient. I bought some rechargeables and a charger and they were useless. Still needing the things and being an eternal optimist I bough a pair of these when they were on special offer. Fantastic. They just run and run. I used them on a Sennheiser wireless mic transmitter/receiver and gave up timing after ten hours. They also come with a dinky Y USB cable so you can charge them both at the same time. If you need 9v batteries these could be your saviour. Expensive but worth it in the long run.

Brilliant batteries so far so good.
These batteries are great and I love that I dont need to keep buying battery all the time. These can also be charge both at the same time using the cable included. So far so good.

1/4 defective - couriers will not handle return
One the face of it a neat solution with USB charging cables.One does not charge at all and Amazons' recommended couriers will not handle return because they are Lithium batteries.No response from customer service about return issues

Woks in my guitar pedal and only takes couple of hours to charge
