Average Run Time Until Rechargeable Batteries

Until these, I had never come across rechargeable 9V batteries. It's a great way to cut down on wasteful disposables.

Much like Coast's other rechargeable batteries, the ZX350 is an amazing piece. It adds longer run time and the lack of need for loose batteries hanging around. I've added it to all my Coast headlamps that will allow it to fit, and went as far as modifying the battery housing of another Coast lamp that wasn't designed for it. Having both hands free and the ability to point and aim my head where I want to see is great, having a battery that is easily rechargeable and gives great run time is even better. It's a win win with Coast's ZX350 battery pack.

I don't know what to say . . . they are batteries, and they work. Every time. Until they die, just like all batteries do. :-)

Watson rechargeable batteries can go an average 7 hours of use with out a recharge, and last several years. Help to save the environment. Only use rechargeable batteries.

Performance with two disposable lithium batteries is average for the current market, but with the rechargeable battery it easily outshines much bigger devices. I'm impressed

I use these batteries in everything. They last a long time for a rechargeable.

These batteries last a very long time, but because they are all rechargeable now I would never have just one.

The battery lasts for a long time . I love using the rechargeable battery over the batteries.

It works perfectly! No need for batteries as it is rechargeable and it last for 7-8 hours but it can run forever if you plug an external battery on the trasmitter (mike) during the use. No problem at all. I Love it!!!

Quality rechargeable batteries.
