If your pick-ups are active pick-ups, then yes they require a
battery(s). Typically that guitar comes stock with passive (non-active) pick-ups and do not requuire any batteries. How ever if they are needed, you need to remove the plate cover directly behind the volume knobs. (located on the back of the guitar). open that up, If it requires a battery, there will be an old one in there more (than likely)
and that should tell you everything you need to know. probasbly a 9volt. good luck

As stock, the Epiphone Les Paul Standard does not use a battery.

Expect to find the battery box under the Esonic logo. Try to find a release for that little panel.

Epiphone is a budget conscious gibson. And probably not made in the USA.
1957 - Gibson's parent company, CMI, buys Epiphone for $20,000, originally intending to harness its upright bass operation, but ultimately reviving the Epiphone name on guitars. A full line of newly designed acoustics and electrics is unveiled in 1958, and two years later Epiphone production moves into Gibson's factory in Kalamazoo, Michigan.

1970 - In the face of foreign competition, Epiphone production is moved to Japan. Through the 1970s and early '80s, the Epiphone line has little continuity, although it maintains respect as a quality import brand.

1983 - Epiphone production is moved to Korea.

1986 - Henry Juszkiewicz, David Berryman and Gary Zebrowski acquire Epiphone and Gibson. The Epi line is soon expanded to include traditional models like the Sheraton, Emperor and Howard Roberts, along with Epi versions of Gibson classics like the Les Paul, Flying V and Explorer.
