Deep Cycle Battery not good for starting??

IF no Regulator ? Then a slow over charging is possible. If your motor start in 1 to 2 seconds ? Battery is probably slightly being overcharged. Better than under charged. Which decreases battery capacity over time. I would just do a low current 2 to 5 amps. charging if boat will not be used in a off season. Or only every month or so. A trickle Charger is not needed if you fully charge it BEFORE a storage. My way and I get 8 years.

Yeah, just purchased a group 31 one for a customers work boat. Made in the USA in Pennsylvania....decent price. Having trouble with a local battery company (father died and the son has screwed it up) and interstate.

Never again.

Go into any Costco with a volt meter/load tester....you might be surprised.

Yes....I never buy a battery without a thorough test first. Also make sure the battery was made within 3 months of purchase !! I take my filtered anytime I shop for a battery....

Yeah, it only charges at 10 amps. So, if I'm only doing short trips from spot to spot fishing, by the end of the day I'm crossing my fingers each time I go to start the motor. I'm wondering if it will make much difference if I had a regular cranking battery. Would it recharge faster of the meager 10 amps?

If your motor starts quickly, the battery should recover quickly, it would take quite a bit of cranking to drop your battery low enough to not restart your motor. Back in my younger days, my motor did not have a charger to recharge the start battery, but I only needed to charge the battery a couple times thru the summer.

I fish bays and the ocean. I have two start batteries and I would never leave the dock without it. Isolated by a manual battery switch....I run on one (alternating) and sometimes start it on two if I believe the battery is down. Have always ran deep cycles but will purchase the hybrids from now on.

Here is the battery company that I was talking about....made in the USA and no used or recycled lead.

I'll be doing some testing as my customer continues using them and will repost if I find anything unusual.
