Note: Battery voltage should be 3.7V and most importantly it must be a PROTECTED battery. If not protected, it can damage the device. Most commercially available batteries are not protected, and that’s why we recommend using Kronos original batteries because the original ones are protected.

Very low temperatures can produce a reduction in the energy and power capabilities of lithium-ion batteries. High ambient temperatures, however, can contribute to a high internal temperature of the battery — which can also decrease performance and power capabilities.In addition to this issue, high ambient temperatures produce further complications and risks. If the temperature reaches a critical point, thermal runaway can be triggered in the lithium-ion battery. German made, Australian Service
