Video Brochure Lithium Batteries need to be charged as soon as the battery power has been depleted. The battery will become damaged and not hold a charge if kept empty too long. Like most electronic products, batteries need to be charged when empty.
Batteries can be recharged 100’s times. The standby time is 3~5 months after full charge where the battery will gradually lose its charge. We cannot guarantee how much charge a battery can hold after 3 months as this depends on the environment the video brochures are stored and whether the video brochure sat with a depleted battery.
