Could not find this battery elsewhere. Perfect fit and function. Got my Digitech GSP 7 working like new, very pleased with this outcome.
This Battery replace my GSP 21 Legends. Ordering was easy and it works great!
I needed a replacement for an Energizer 523 and this one fit the bill. This is a keep alive battery for my Digitech 256XL effects processor which is an old piece of audio gear I still use. The battery is obviously 3 1.5 volt cells put together, but it fit right and works. The last replacement I purchased from a different supplier went dead within a year. I am hoping this one will last longer. Good
We have an old hand held mic that uses these batteries. . . we use this mic every Sunday for sharing during the worship service. Locally, these the batteries for this mic are very expensive. . . glad we could find an alternative source.
great price with shipping, fast delivery
After 18-months in office storage (environmentally controlled), all (10) of these were between 3.3 to 3.7 volts.
I had a 40 year old professional condenser microphone that requires a battery that is no longer available from most sources. I'm glad I was able to find Battery Mart - because this battery allowed me to use a very high quality device that would otherwise have been obsolete if I was no longer able to get the replacement battery.
