The remote control module consumes tiny amounts of battery power (about 2 mA) when the ignition switch and battery switch is left in the active position. Nevertheless, it might take around two weeks for the remote control module to actually drain the battery. If you start and use the inverter generator for a few hours, then the battery will be recharged automatically during normal operation. This is only a problem if you forget to turn off the ignition and battery switch before storing the generator for a few weeks. Accordingly, you should remove the battery and put it on a battery float charger to maintain the charge over a long period. If you are using the generator every day, then the battery will be slowly recharged while the generator is running.
