Which device must be turned OFF and left off for at least 30 seconds before replacing a low-charged battery?

• A. SKL
• B. KIK-11 Tactical Key Loader (TKL)
• C. KOV-21
• D. TRKEK interface

Answer: (A)

The main idea is safety and data integrity when changing a battery in crypto-loading equipment. The Simple Key Loader (SKL) must be turned off and left off for at least 30 seconds because it can retain energy in its power rails and internal storage capacitors even after you power down. If you replace the battery while energy is still present, you risk arcing at the battery contacts, potential damage to the unit, or inadvertent power-up that could corrupt volatile memory or expose crypto material. Waiting the 30 seconds ensures all residual charge dissipates and the device is safely de-energized before re-seating a new battery. Other devices listed don’t carry the same immediate risk from residual power during battery replacement, either because they don’t store energy in a way that requires a delay or because their power-down procedures don’t mandate the extended wait. The key point is the SKL’s combination of energy storage and the sensitivity of its cryptographic functions necessitates that delay.
