Later weapons used the more reliable ram-air turbine-generators or thermal batteries.

The release also activates a thermal battery to provide power for the bomb's laser detector and computer.

The mass of the oven acts as a 'thermal battery', which slowly releases heat over time.

The battery delivers current for a short time (seconds to a few minutes), but some thermal batteries can be stored 10 years or more without deterioration.

Pyrotechnic heat sources are often used for activation of thermal batteries, where they serve to melt the electrolyte.

The thermal atomic batteries on the other hand, convert the heat from the radioactive decay to electricity.

The missiles needed fresh thermal batteries that could only be purchased from the US.

Historically, thermal batteries have often been used in guided weapon systems such as surface-to-air-missiles.

Referred to as thermal batteries, the electrolyte is solid and inactive at normal ambient temperatures.

Examples include automobile airbags, thermal batteries and missiles.
