Abstract
A retrofit module electrically connects to a device's battery terminals, where an original main battery would otherwise connect to the device, and a hot-swappable battery electrically connects to the retrofit module, thereby retrofitting the device for operation with hot-swappable batteries, without shutting down the device to swap the batteries. When a charged hot-swappable battery is connected to the retrofit module, the retrofit module powers the device from the hot-swappable battery. The retrofit module includes a bridge battery and a circuit that charges the bridge battery from the hot-swappable battery and that provides power to the device from the bridge battery while the hot-swappable battery is replaced. The retrofit module may include a releasable structure that maintains the module in contact with the device's battery terminals, even after the hot-swappable battery has been removed. The retrofit module may have a form factor and power supplying terminals similar to those of the main battery that the device is configured to accept.
