Abstract
An intrinsically-safe battery assembly (200) for field devices, includes an intrinsically-safe battery (206) and polymeric chassis (204). In an example, the polymeric chassis (204) is removably coupled to the intrinsically-safe battery (206) and has at least one retention mechanism (224, 226) configured to engage the intrinsically-safe battery (206). In another example, the polymeric structure (204) has at least one battery ejection (228) mechanism configured to eject the intrinsically-safe battery (206). A field device (100) is also provided.
