Using an aftermarket (non-URC) would only void your warranty if you return it for any other reason within the 1 year warranty.
Thanks, Joe! I'm well beyond the 1-year warranty period. I was just worried that an aftermarket battery could somehow damage the remote, or that it wouldn't work as well as the original battery.
