Each battery contains 40,000 curies of radiation, she said.
The batteries' maker X-rays each battery before shipping to look for possible defects.
Tesla says it encloses each battery pack's 6,831 cells in steel to protect them and dissipate heat.
Electric vehicles in particular would benefit, as the weight reduction would translate into longer driving distances on each battery charge.
Although at present only 4% of each battery is made from recycled parts, the company hopes that by 2025 this will rise to 40%.
Each battery contains multiple rounds of guided missiles that can intercept and destroy other missiles and hostile aircraft flying at high speeds.
Resistors are arranged in series with each battery to establish steady-state operating conditions, and an AC signal source is contained in the base lead.
Each battery stores direct current (DC) electricity at a fixed voltage determined by the panel specifications, although load requirements may differ.
But some battery experts said that scans might be unable to detect minute anomalies in the battery, like trapped micro-shavings in any of the tightly wound conductive material used in each battery's eight cells.
"The heaviest unit in the device is the inverter, it's 40kg; the battery enclosure we bring out next month is 25kg and each battery you place inside it is 20kg and they're all outdoor-rated," Livingston said.
