dwendt1978 Posted January 6, 2007 Report Share Posted January 6, 2007 Figured I'd just try and find out how everyone stores their batteries in the winter time. Looking for anything I might (or others) be missing. I just pull them out clean them good, throw them on a trickle charger for 2 days and set them on a chunk of wood in the basement.

basskat Posted January 7, 2007 Report Share Posted January 7, 2007 I never store my boat but did attend a seminar that had a guy from AC Delco there talking about batteries. They do not reccommend trickle charging batteries. They suggest that you fully charge them with 10 amps. Batteries should be stored fully charged. He also stated that you do not have to store them on wood anymore. I still store extra batteries on wood myself. While we're on the battery subject, I've been using the AGM batteries for four years now. These things are awesome. I run a 36 V 101 lb thrust trolling battery and have three AGM batteries. I've never came in and plugged the charger up where they were less that 85%. They cost a little more but are well worth it. Quote Link to comment Share on other sites More sharing options...
Z-Reel Posted January 10, 2007 Report Share Posted January 10, 2007 I agree basskat AGM batterys rule, I leave mine in the boat, I disconnect all accs. and leave my Pro Mariner on board charger hooked up. I then plug them in about every 6-8 weeks just to check the charge. I live in the cold north country of SD and this works great for me.

Jason Posted January 17, 2007 Report Share Posted January 17, 2007 I have mine in the plastic battery box in the back hallway with a solar powered trickle charger on it. Is that bad? Quote Link to comment Share on other sites More sharing options...
basskat Posted January 18, 2007 Report Share Posted January 18, 2007 The question I would ask is does it shut off when the battery is fully charged? If so then I don't see a problem. If it charges continuously then it could over-charge the battery which will cut into the life of it. If it were me I'd fully charge them and take the charger off. About once a month check and see if it needs a little boost. I'm by no means a battery expert but I've owned boats for over 30 years now (yes I'm an old fart) and it works for me.

Z-Reel Posted January 18, 2007 Report Share Posted January 18, 2007 If your battery's are the AGM style, you donot want to over charge. The Pro Mariner on board battery chargers say you can leave there chargers plugged in because they sense the battery charge, but I have talked to there tech guys and they recommended once fully charged un plug the charger. Over charging can be a big killer on battery life. Pro Mariner said to run the biggest battery's you can, the less life you take out the quicker they charge and the longer they last. I run the group 31 AGM batterys, I can fish all day wind or no wind and come in with still over 12v in my batterys, and my Pro Mariner 20amp charger has them fully charged in 4-6 hours. Don't mean to brag up on Pro Mariner Chargers but they rock and there customer service is great. Quote Link to comment Share on other sites More sharing options...
