It's more likely that your battery is just going dead ... What all are you running off of it, and for how long before recharging? Just FYI, most modern electronics have some parasitic power consumption that allows them to watch for use of the remote control to turn on, or other things of that nature. Refrigerator, safety sensors (CO monitor, etc.) also draw power. They'll drain your battery even when turned off if given enough time.
