Subject: Batteries for 89 PT40 Author: Gus Rodriguez [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 01/ 6/ 08, 12:23pm I am the proud owner of a new to me 89 PT40. I have several issues that need attention but will attack one at a time. My BB is slow to start, as though not enough battery power is there to really crank good. I have six trojan 105 batteries in the engine compartment, but they are all deep cycle, and one battery up front for the generator. Is this a common configuration or did the last owner replace the batteries with the wrong type? What is typical for my BB w/ an 8V92T? Any and all info appreciated.

[> Subject: Re: Batteries for 89 PT40 Author: Ernie Ekberg [ Edit | View ] Date Posted: 01/ 8/ 08, 2:34pm Gus, i have Trojan 105s in my coach. They have served me well. That is the original configuration, I believe. Others have added more batteries. It depends if you intend to dry camp a lot. We like to be plugged into 50 amps.

[> [> Subject: Re: Batteries for 89 PT40 Author: Gus Rodriguez [ Edit | View ] Date Posted: 01/ 10/ 08, 9:53pm Ernie, do your trojan 105's supply the engine for starting purposes also or do you have a separate set for engine alone? I did some research on the trojan 105's and they do not have any data for cranking performance. If anyone has added some batteries for cranking purposes please share the information. Thank you.

They are all tied together, thus my dry camping days are numbered by minutes, instead of hours. I also have a separate battery for the generator. Ernie [ Post a Reply to This Message ]

[> Subject: Re: Batteries for 89 PT40 Author: Shane Fedeli (85PT40) [ Edit | View ] Date Posted: 01/ 12/ 08, 3:50am Hi Gus, Our PT 40 came with 6 6-volt cells originally. All were tied together and served both engine starting and house light/power purposes. When I bought the coach, the batteries were heavily corroded and did a poor job of holding much power. I replaced the older charger (the cause of the problem) and installed a Xantrex 3-stage (Prosine 2.0) charger/inverter. At that time, all of the old batteries got replaced too with Sam's Club (Eveready GC-2) Golf Cart batteries. They have worked flawlessly and easily can provide power for a day or two while dry camping before needing a recharge. I've had no problems starting my 6V92 in temps down to 40 degrees, even without the block heater. Another thing to make sure of is that your chassis and starter ground straps are making good contact with the frame. Get some sandpaper or a dremel tool with the wire brush attachment and clean those connection points. Coat the cable ends and mounting surfaces with a small amount of dielectric Silicone grease.
