Hi guys, I had my boat out Sat. and she ran fine all day. I played around with the boat on sunday, getting ready to go fishing for three days. I got to the lake Mon. morning, launched the boat and tried to start her up… nothing. Jump it off the trolling motor battery,and ran around for 20 minutes or so. I was a little worried about it starting again so i fished close to the ramp. Started it a couple of times to check and thought it was good. went to move to another spot and she would not crank over. I thought maybe I had left a switch on while playing around on sunday. loaded the boat with the TM and went up to my dads house and charged her up overnight. She ran fine the next day, started every time I went to move. Went back to my dads plugged her in overnight then went fishing this morning. Started fine first thing, then after about 3 hours I went to move and it just barley started. I ran her back to the ramp and loaded her up and drove home. When I got home I checked the batteries with a volt meter. The trolling batteries were at 12.6 volts and the cranking battery was only 11.5 volts. Do you think it is time to replace the cranking battery? I was bummed because the topwater bite was on! Thanks for any advice and sorry for the long post. Ed

Definately replace, what electronic equipment are you running? What size engine and battery?

Time to replace it. 11.5 volts means its toast or on its way for sure. Get the biggest cca you can fit in your boat. Ive been using a Sears PM1, seems to be a good battery so far. 3 years old now. Batteries can go bad after 6 months or they might last 6 years, you just never know. I have had them go bad in 2 months before.

That battery sounds like it is history. That 24 xhd has plenty of cranking amps for your sho, but only has a reserve of 135. If you have poles, electronics, livewells running, etc., then with a low reserve like that you are running it down. 24 series batteries are not commonly ued in bass boats. A 31 series will have a few more cranking ams but a lot more reserve. AGM or flooded is a personal preference.

Thanks guys, I told my dealer that the cranking battery looked small but he said they use it in all of their boats. I think I will check out a 31 xhd or a sams club duracell 31 agm. Thanks again Ed.
