Battery STC for Piper Warrior

[Brenny]

I'm in the process of trying to purchase a Piper Warrior. Recently purchased a copy of Aviation Consumer's Used Aircraft Guide and in the write-up about the Warrior they mention an STC that involves moving the battery from under the rear seat to the firewall inside the engine compartment. Apparently this improves starting, shifts the GC forward considerably, allowing for more baggage in the rear, and increases the useful load by 115#. They don't mention where to obtain the STC and I've been unable to find any information on it. I've called Aviation Consumer and left a message but haven't gotten any reply. Also looked in the AOPA STC database for the Warrior and didn't find anything. Does anyone out there have any info on this STC?

A lot of pipers used cheap aluminum battery cables that have very poor capacity, coupled with poor condition make a poor hot starting airplane. Just replace cables with good quality copper cables of a bigger size and have good clean connections and it will start fine. You can make better cables than you can buy. Aircraft Spruce carries a really nice tefzel cable that is tinned fine strand copper in various sizes. Crimped and soldered these will outlast the airplane. Just make sure to use big enough cable, don't let solder flow into cable too far, and use good shrink wrap to finish nicely. Sometimes the regulators on airplanes don't really top off the battery like they should. Need to know if your really getting 13.8 volts for starting.
I don't know where to look for the STC, probably an owners club if there is one. I do know what an overgrossed Archer on a hot day performs like and would guess not too many people want to carry more weight.
