Advantage Roof Cleaning Report post Posted February 5, 2014 I thought I posted this. Was the same question posted in the other forum? Perhaps I'm loosing it. Regardless, attached is an image. You will see two black boxes. One houses the battery, the other the pump. Looking at the image on the bottom left, you can see the pump in the box with the fan mounted above it.

Roof Cleaning Virginia Report post Posted February 5, 2014 Hi Jonathan - sounds like analysis paralysis has set in :-) Seriously, any run-of-the-mill deep cycle battery should work just fine. I'm not familiar with the various brands or stores in the UK, but dug this one up on line http://www.barden-ukshop.com/powermax-85-marine-and-leisure-battery---free-uk-delivery-526-p.asp I only have one here at the house at the moment and the label is worn so I can't see the AH. For reference, the CCA rating is 800. We do 5-10 roofs a day during the busy season and the only time a battery has died on us is when I forgot to recharge it the night before. Carry a back up battery if you choose, or simply use your truck battery in a pinch. Some have tied their batteries in to their trailer wiring harness so that it charges while in route. Good luck!

PeakOfPerfection Report post Posted February 7, 2014 I would start with the biggest wet deep cycle battery budget will allow for. The more amp hours, the better. Gel is more expensive, but one good gel Cell can give you the longevity of two wet cells without the maintenance and it will last longer. Good Gell cells allow you to use a much larger percentage of their reserve before the voltage drops. Wet cells are less money but have a smaller amount of energy they can store before the voltage starts to drop. Two batteries can have the exact same amp hour rating but the more expensive Gel cell will allow you more run time and they last longer. If you go wet cell, remember to regularly check the cells for water. Weekly during the busy season. Charging and recharging will lose water and you will end up with an expensive dead battery if you don't keep it topped up. As for recharging from the alternator....I was told by a battery expert NOT to do this with a true marine deep cycle battery since it will sulfate the cells faster, shortening the life. You CAN buy a 12V deep cycle charger system....that is what they run in larger boats! Just make sure to monitor things so you are not short charging the battery. You can charge a hybrid starting/deep cycle off the alternator because they are designed to be fast charged off the alternator...but they don't have the reserves of a true deep cycle. For pump applications, it is better to use a true deep cycle battery to begin with. Only use jumper cables in a pinch if you run low. Then again, get a big enough battery and running out of power won't be an issue. Deep cycles do have a weak point. They need to be run down. Before being recharged If you do one hour jobs once a day and recharge the battery, you will kill it. A marine deep cycle battery monitor is on my list of goodies to get for the new rig.

Apple Roof Cleaning (813) 655-8777 Report post Posted February 7, 2014 Many thanks yeah my wife says I over analysis things, I guess it's true lol Jonathan LOL, analysis is paralysis my friend. Back when I ran 12 volt pumps, I used whatever high rated deep cycle battery I could get my hands on, for a good price. The boat and fishing guys know what ones are good and bad, go down to a marina and ask around, ask the fisherman who use them for trolling motors. Keep them far away from the chlorine, because chlorine and battery acid will go BOOM. Seriously! I was told not to worry about an old broken down car right next to a roof I was cleaning. The chemical got on the hood, and found it;s way to the battery, and blew up! Seriously, the explosion dented the hood of the old truck, but the owner was cool, and just laughed! 1 Yorkshire Driveway Cleaning reacted to this Share this post Link to post Share on other sites

Apple Roof Cleaning (813) 655-8777 Report post Posted March 13, 2014 Hey up mate, what are you needing the battery for in the first place? He probably never read this thread Simon and never realized that plenty of roof cleaners are running 12 volt roof cleaning pumps w/o a battery! These 12 volt power supplies can simply be plugged in at the customers home, or, you can use them with a small generator. A 12 volt power supply has many advantages over a battery, because unlike a 12 volt battery, it never runs down! Share this post Link to post Share on other sites
