Extra battery

I've always just gone with one.
 
No, but I have been reading the latest posts on the electronics that auto-switch between batteries depending on charge. I like it and think I'm going to attempt an upgrade this spring to run the amp I want to install. :grin:
 
I have two batteries on my 200 Sundeck. So called dual w/switch. Run with switch in position one or two. Cruise Southern Lake Huron and it makes me fell safe knowing there is a back up battery.
 
Yeah, I think I'm going to mount an extra batt back by the stock one. Nothing too fancy, just a mounted batt that I could use if needed!

Thanks for the replys!
 
I keep a DieHard Portable Power 750 battery charger in my car in case of an emergency. It has a light and 12V charger on it as well. So, when we head out for a day on the boat, I bring it along coolers, rafts, food, fishing gear, kids, etc....I'm amazed the boat still floats!:smt043

Haven't had to use the charger....yet. :smt038
 
This is something I need to stop saying that I need to do, and just get it done. Nothing worse than being stuck in the middle of the water with a boat that won't crank. OK, I guess there are worse things, but I'm just saying.
 
If you don't want to install a second battery, you can acquire a portable Jump Start Kit/Power Pack for under $100.

Really? I'll have to check into that. Thanks.

I agree.....I'm constantly thinking about my battery when we're on the lake, boat off, listening to music....I do NOT want to get stuck because I drained my batt!
 
I added a second battery to my old 220 sd. I spent about 10 times longer thinking about it than it actually took to do it. The second tray screws down in about 20 seconds. With cordless drill of course. The single battery switch comes off in about 60 seconds. Installing the dual battery switch doesn't take long, the trick is to get the battery cables made up. Luckily for me the local MM mechanic is a great guy, he made them up for me. After watching him it is really pretty easy. You get the battery cable, end lugs and some solder. Take a vise-grip or bench vise if you have one and clamp the lug, heat with torch then fill with solder. carefully stick the cable stripped end into the molten solder. Done. Install cables to new battery and switch. All and all probably one of the easiest mods to do.
Once it was done I would just alternate the batteries each day. Playing the stereo to my hearts content.
So stop thinking:smt024 and get to doing.......:thumbsup:
 
If I do the stereo upgrades with the amp I will upgrade to 2 batteries. I have the Blue Sea combiner and switch. will need some new battery cables. I want to relocate the switch so I don't have to lift the jump seat to switch anyway.

What type of solder for the battery lugs? Advanced Auto Parts has the lugs and cable by the foot.
 
Rosin core solder, heat shrink to seal.

Not that I'm endorsing Wally-Mart, but take a look at this link. You might need something a bit larger for your motor, but there are a million products like this out there:

I have this exact powerpack......It is great.
The situation of running your "cranking batt" and slowly draining it with a stereo, air pump, etc is not a good practice from things I have read. You should have a "deep cycle" which is made to be slowly drained and re-charged. The switch is not real expensive and the peace of mind is worth it. This is especially true if you plan on adding extra components.

I am sure others more versed in batteries will give a better description
 
I'd like to run a amp, a few more speakers with a two batt combo set up. Are there any known problems with upgrading a stereo, amp, etc....with the stock alternator? Or will this set up be just fine?
 
The set-up should be fine. Make sure you hook things up correctly.
Like I said, I would have a marine cranking for starting and a deep cycle for running your stereo, gadgets etc. .
There are some guys wha have done some nice stereo upgrades.
Do a search for "stereo upgrade" and you should find plenty of reading

W2F,

Where do you plan on mounting the amp and the new battery switch? I'd like to get that switch out of there as well.
 
Good post I am also thinking of adding an extra battery as well. Does any one have any experience with the new SR my ignition switch is in my battery switch. You put the key in the battery switch turn it to unlock the switch, then flip a switch on the dash to start. I run an amp and would like to have the added protection.
 
Soldering is not the prefered way to make up a battery cable. The best way is to use pre-tinned marine grade cable and crimp on the the lugs. Using auto grade cable and/or soldering are poor substitutes.

Be especially carefull if you try to solder cheap auto cable. It's not tinned so the solder won't flow very well and the insulation is cheap so it will melt while your trying to get the solder to flow.
