The R20 battery, known simply as a battery in game, is an item that is required to power the player's portable radio and flashlight, available in boxes of four batteries at Teimo's shop for 34.5 Mk each. The batteries take the form of 1.5V D dry cells manufactured by LEAD ER, which also produces 12V wet cell batteries for cars. The radio requires 10 batteries, while the flashlight needs 4.
The batteries are inserted through the compartments at the back of the radio and flashlight, which are opened by pressing F
. The batteries will then need to be manually removed from the boxes, also by pressing F
on the boxes, and inserted individually into the compartment using LMB
when a check mark icon appears. Inserted batteries can be removed by pressing F
on any of them, but they will be labelled as "disposed batteries" and can no longer be reused, even if they are freshly inserted. Battery power drains over time, and they will eventually need to be replaced.

- "R20" is an IEC naming convention for zinc–carbon D batteries while "UM1" refers to an alternate designation by JIS for the same type of batteries.
