What the thread found

• A third-party battery adaptor designed for older Preston follow focus hand-sets can power the device using standard batteries instead of proprietary ones.
• An uncharged standard battery inserted into the Omnishot adaptor was able to power a Preston follow focus for approximately one and a half days of typical use, with one of three battery indicator lights remaining illuminated.

Depends on

• The adaptor was tested on a Preston model purchased in 1999, so compatibility with other Preston models is not documented in this discussion.
• Only one adaptor unit was tested, so long-term reliability is not established.
• The test lasted one session of unclear intensity, making it difficult to extrapolate battery life under different usage patterns.
