Another Battery question
Last week I had a pressure test on my lower end to check for a bad seal. Everything was fine with that, but apparenty the guys working on it bumped a few of my power switches on and when I tried to start my motor at the docks on Saturday the battery was dead.
I have a back up on board, so I just grabbed the cables and gave it a boost. Started no problem.
Then I trolled for 7-8 hours. Will the battery be charged up now? Or will I find myself needing abother boost when I turn the key again?

Re: Another Battery question
Markus...was it a deepcycle battery? If not you may have a problem bringing a dead regular cranking battery back to a full charge. I would place it on a good battery charger or take it in to be cycled and tested.Markus wrote:Last week I had a pressure test on my lower end to check for a bad seal.

Oh ya...go out to your boat, trip the kill switch and try to crank it over...you will know if you have any power
Goodluck...

M: As long as it was a starting batt (which I assume NO ONE on this site would EVER use a deep cycle for starting!! You'll be fine....or else you've got other issues with the charging system on your motor. I've been there before and just idling out of the harbour was enough to get it going again after stopping to fish for 1 hr....that's with a 40 amp charging system (v6 merc) so yours might be a bit different depending on your motor.
when in doubt....slap the earmuffs on her (your motor that is....)

battery
I use a dual purpose battery ,you can buy various brands that are for starting and deep cycle combined. I always used a deep cycle for starting and running accessories,a regular starting battery will not last long running all the extras on the boat. roughrider
Hi Markus
If you were trolling for 7 or 8 hours the battery should be fully charged.
That is assuming all the variables are ok.
Fluid level in all cells - ok
All connections clean and tight
You were not running too many accessories
If you still have concerns, invest in a small inexpensive digital multimeter (Radio Shack) - A reading of 12.5 VDC or better with the motor off is a reasonably good indicator that the battery is fully charged.
PM me if you have any more ?

I assume Markus is running a kicker and is receiving no charge back to the starting battery while running accessories. MT is right, you need to run high RPM's to recharge the main battery,depending on motor altenator size. In this case,a seperate battery for accessories would be insurance your starting battery will work when needed roughrider
Markus...
If your alternator/generator on your motor is working fine....10 mins will charge your battery enough to get you started again, if that. Also, a "deep cycle battery" does have cranking power, not just longevity...I used a 27 series delco voyageur for cranking and running electronics for 4 years for example....even then just retired the battery for lights on the duck boat...good luck

Thanks for your help guys. RR, I just finished mounting the new kicker on yesterday. (I decided to go with an independant fuel tank and line.) So my 90 outboard was hopefully charging the battery. I put the muffs on it last night and it turned over nice. I'm just hopping that if I have to turn it over a fewtimes, will it have enough power to do it. We'll find out Saturday morning. Thanks for the help guys.
