deep cycle marine battery

3 posts in this topic

I was out fishing the other day and noticed my trolling motor was losing power prematurely, i find out my battery has no water in it, i was wondering if this battrey is now shot or can i add water to it and slow charge it back up with a smart charger? any info would be appreciated.

By adding water now you will get a little more power out of it however the damage has been done. Hopefully you can milk it for the rest of the season then buy a fresh battery next spring.

Consider this a good learning experience. Wet cell batteries generate heat when in use and especially while recharging and along with this comes evaporation. For this reason one should check the battery fluid level periodically. You don't want to let it get below the level of the plates so they become exposed as this contaminates them. The best water to use is distilled but I have had good luck using filtered and softened well water although I'm sure it still introduces contamination that distilled water would not.

      What a novel concept!  Talking fishing on a fishing forum to increase interest and activity.  You may be right, it could work!

      So let me see if I understand this? You guys on the last page or so are going to "Lets Save This Forum" by high jacking the thread and talking fishing now!     Dam that could just work? Carry-on!   Good Luck.

      Thanks guys for the tips looks like 3-4inch stick bright stick baits and bright spoons seem to be the go to.  Anybody ever vertical fish them or live bait? Hope the weather is.good next friday, i have always wanted to get out there and try it.  Bonus is the wife would be happy with some fresh salmon.

      I have been looking at the gages this morning and the L.F. still appears to be either frozen or have an ice jam at the most downstream gage in Little Fork. The discharge is not working but the water level has risen 3' since Sunday. The next upstream gage however is flowing good and has risen from 1,200cfs to 5,000+cfs since Sunday and has risen 8' in the same period. The Big Fork doesn't have cfs data so I am thinking its frozen but the height has risen 2.5' since Sunday. I would think with that flow and the warm weather it's only a matter of days until they both go.   Other trips like the Black River and Rapid River are all on the rise both cfs and height.   Also, I took a look at the Rainy at Manitou Rapids and it has risen about 2' and has gone from 14,000 cfs to 17,500 cfs since Sunday.

       I'm heading up Friday. Going out of spring steele. I have a delivery route that took me up there today.  Took lunch at the warroad access. They got it closed with yellow tape.  If anyone heads up earlier an update would be great.  I'm planning on an atv but will walk if I have to.  Thanks.  Good luck and tight lines!!!
