What to remember when flying with lithium batteries - SilverKris

"Flights operated by the carrier permit lithium‑ion batteries up to 160 Wh and lithium‑metal batteries, and allow devices with high‑voltage batteries (such as wheelchairs and mobility aids) provided you notify reservations and airport check‑in staff at least 48 hours in advance. Loose lithium batteries are prohibited in checked baggage, and lithium‑battery powered transport devices (for example hoverboards and mini‑Segways) are banned in both carry‑on and checked baggage. To reduce the risk of overheating or short circuits, insert lithium‑metal batteries with the correct polarity, keep batteries away from metal objects and other unpacked batteries, avoid covering chargers while in use, disconnect chargers once devices are fully charged, do not place heavy objects on devices or expose them to water, and do not leave lithium‑ion batteries unattended while charging." - Silkwinds, the inflight magazine of SilkAir
