Super User Log Catcher Posted February 20, 2019 Super User Posted February 20, 2019 Just because a battery is sealed thinking it is maintenance free is wrong. You still have to clean the the terminals and the connectors that hook to the battery periodically. I learned this the hard way when my motor quit one day and I came back in on the trolling motor. All I did was clean them and everything was fine. Quote

They have dual purpose batteries for 80 bucks and a great return policy. Sometimes they have a crank battery for $69.99 Quote
billmac Posted February 21, 2019 Author Posted February 21, 2019 Looks like there isn't one within 250 miles. Quote

I used a small stiff wire brush like plumbers use to clean copper fittings. I also used sandpaper on some the small terminals that hook to the battery. Quote

Super User WRB Posted February 23, 2019 Super User Posted February 23, 2019 You must have a Walmart near you! Walmart carries their brand Everstart in marine batteries, look at them. Tom 1 Quote
billmac Posted February 23, 2019 Author Posted February 23, 2019 Walmarts we do have, in abundance. Quote
billmac Posted February 23, 2019 Author Posted February 23, 2019 So what about chargers? As I said, it was in my mind to just get a couple of float chargers (assuming I run two separate circuits, as we've been discussing). Good idea? Bad idea? Thanks. Quote
o2bfishn@frontier.com Posted February 24, 2019 Posted February 24, 2019 I love my AGM battery. I run a 12v system with one battery. 25hp johnson and a 55pound motorguide Xi5 on front. I was buying a new deep cycle every other year, so I decided to spend double the price for the AGM and I am on my 5th year with it working as good as new. The 25hp charges the battery and many times when I get home from a day of fishing the charger says The battery is already 100% charged. As far as a charger be sure to get a automatic charger that way it does not over charge the battery. I have burned up one when I forgot about it. The one I have has a AGM battery setting. Quote
OnthePotomac Posted February 24, 2019 Posted February 24, 2019 I over did it, but use an Interstate size 27, 850CCA amps and 1000MCA to start my Yammie 60 hp and run two sonars (a 5" with GPS, etc. and a 7" with down scan) and pumps. My 12V TM is a 55lb digital 10 speed MG and I bought a size 28 Deka, which, as I recall is 550CCA and 200 minutes reserve, which I charge immediately after leaving the water on a 10amp automatic charger. I can stand on the TM for six or more hours (tidal fishing) and never come close to draining my TM battery. The average of the TM for the day is probability a "5". The boat is a 17'6" G3. Quote

If you can't put in permanent chargers I'd use this. I have used this for a few years on my starting battery, no problems. And only $17. Maybe someone will say these are bad, I don't know. https://www.amazon.com/BLACK-DECKER-BM3B-Automatic-Maintainer/dp/B0051D3MP6/ref=asc_df_B0051D3MP6/?tag=hyprod-20&linkCode=df0&hvadid=198093653755&hvpos=1o2&hvnetw=g&hvrand=11131349938213414801&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9060340&hvtargid=pla-357964576938&psc=1 Quote
Super User slonezp Posted February 24, 2019 Super User Posted February 24, 2019 Charging the batteries immediately after they are discharged should be your first priority. Charging them at the highest amp you can should be your second priority. There is nothing wrong with a trickle charger but there are better options. Quote
billmac Posted February 24, 2019 Author Posted February 24, 2019 I've looked at that B&D charger. It looked like it would work. Quote
