You are watching a fresh lithium battery BR-2/3A suitable for the Ensoniq ESQ-1, SQ-80, SD1 and VFX-SD among others.

This battery requires soldering, although it is really straight forward to replace if you can handle a soldering iron.

I have a huge collection of synthesizers, I am always available to help in stuff related to the ones I own. From Ensoniq I have the ESQ1 and VFX and I can provide EPROMs (with the latest software and the extra waves), the batteries, pots, the CEM 3379, and the SSM2300. Check my other items - decent prices for top products sent immediately, well packed and tracked mail.

I have sliding pots for most vintage gear, including most Korg, Yamaha and Kurzweil. Some rotary for older Moog (Micromoog) and Transcendent 2000. Also some switches and some SSM and Curtis (CEM) chips. I will be selling all these in the next few weeks. Contact if you are looking for something. I repair (and collect) synthesizers since 1992.

I will send worldwide (tracked) for free. I'll ship same day or next, depending on payment hour.
