I have an 07 4stroke 150. Sometimes I can be riding all day and when I stop the motor stalls. When I try to start it back it acts like the battery is dead. So I switch batteries and off I go. Both batteries are good and fully charged. My charging system
checks out good. the motor cranks up fine at the landing and should be charging
during the ride. It doesn’t do it often but enough to worry me. I have noticed it after WOT. Yesterday i had to use both batteries to start it. I switch back to one battery after about ten minutes of riding . Shut the motor down and it starts fine.
Thanks for any replies and help with this problem…

I’m thinking my batteries are charged but after reading on another site I’m using the wrong kind of charger. I was told that a standard car charger doesn’t charge marine batteries 100%.

You were told wrong…don’t "fast " charge the batterys just use the lower amp charge setting, it will work fine…
If the batteries are good, take the connections off, wire brush or emory cloth them, put some di-electric grease on the connections and secure them on the battery terminal with a wrench.
Any corrosion on the terminals and/or not on the battery tightly will cause this.
load testing the battery is the only true way to check the health of your battery.
think electric strip heater connected to jumper cables with a volt meter attatched.
autozone, advanced, etc, can load test a battery for you in about 10 seconds.
we can also do it, but we may not be as close as one of those places.
Thanks for all info guys. Yes I always slow charge them. Ill have them tested and clean the connections. The info on the charger can from someone promoting. Battery tender charging systems.

I saw the episode of Ship Shape TV that had the guy from Battery Tender. He did say that a marine charger had to be used for Marine batteries. A automobile battery charger will not charge a marine battery to a level of 105% but only 95%. Each following charge would be 95% of 95% and so on until you no longer have a charge strong enough to maintain the battery.
