been using my logitech harmony 600 remote for 4 months now, not changed battery yet. And it is the only remote i use to control tv, starhub, htpc, kdk fan remote in my living room.
Got a harmony 525 & Marantz RC 2000 Mk 2 universal remotes I hardly use because I got tired of replacing the batteries :(
Using the original remote of my aircon, TV & fan will last long, long time but those fancy learnable remotes go through batteries. I tried using rechargeable batteries but those type of batteries got no staying power.
Better keep the original remotes handy
