Should be, I was using the Novopen Echo and used a Frio wallet to keep the pen cool in the hot weather, never had any issues with the battery and it didn't develop any faults.

Odd that they didn't reply to you Paul, but perhaps you were unfortunate to have a faulty pen. If unsure ring the Novo Nordisk Customer Careline, they'll say for sure if storing the pen in a Frio Wallet is fine or not.
