Suspected Burn From a 9-Voltage Battery.

Advancements in technology allow for the utilization of low-voltage battery-powered devices for patients admitted to the hospital. There have been rare cases of burns due to leakage of the internal contents from low-voltage batteries, but to date, there have been no reports of electrical burns caused by low-voltage batteries. We present the case of an 89-year-old female who presented to the general surgery service with a suspected electrical burn from laying on a 9-volt battery.
