Got the new registration for our '17 AR190 this afternoon. Went out and put the stickers on, thought I would sit in the boat and drink a beer and listen to the stereo for a minute. Maybe clean a little.....NOPE....Dead battery.....It appears I left the switch in the "on" position for the last month or so. OOPS.

No big deal right, hook up the charger and wait a bit, and it should be good to go.....Nope....Charger is giving me a flashing red light that means "Battery not charging". Check connections, then grab a multi-meter....hrmmm, 1.19Volts.....That seems bad on a 12V system.

SO......My question is this.....Can I drag the boat out of the garage, hook it up to water, then jump start it to let the engine recharge the battery? If not, is this battery just junk at this point? Would really hope my slightly less than one year old battery isn't ruined, but that would be my luck. I have the time, truck, cables, and spare vehicle to get the boat started if that is an option.

Any thoughts?

Here are the battery and charger in question if it helps

Not sure about your specific problem, but that is not really a charger despite its name. It is more suited to keep an existing battery at full charge, not charge a depleted battery. .75a is the max output.

Take the battery out and have it tested. If it's still good I would get it on a real charger.
 
The stator on our boats isn't a powerful battery charger, you'll need to charge battery up via another means
 
You probably need to jump start the charger. Most chargers like in golf carts, will not turn on if voltage is too low. I would unplug charger, connect jumper cables to dead battery to ensure 12 volts (or close to it) to it, plug in charger, then disconnect jumper cables. The charger should continue to charge the battery but will take a while. Do it all the time with golf cart batteries. But I have no experience or knowledge with that charger.
 
Onboard charger time :)

Just kidding, but a cheap 2/10/50 charger/jump starter is a great addition to a household. Even a 2/6 amp charger can be had for 30 bucks and is a good investment that will work for many many years.
 
Fastest approach is to just pull the battery out (I use twist ties to tie off all the wires in groups for each terminal so you get them all back on again) and take it to Advance Auto, have them do a free test and free charge if it passes the test (takes ~45 minutes).
 
Sent out an APD to the neighborhood tooluminati group. Next door guy has a full blown charger in the garage we're going to try. We might or might not drink a beer or two while we're at it.

Thanks for the tips!
 
I know there are a few charger threads, but do we have a dedicated one for the best set-ups to keep the batteries charged? I notice running the boat does not charge them well. I have seen a few people install a plug on the side of the boat, I want to hear more on that.
 
I bought this last year at the end of the season and will be installing in the next couple weeks.

Ran the "big boy" charger for a few hours last night, battery voltage came back up to 11.8V and let the tender take over. Been on the tender all night. Going to go check on it after a few cups of coffee this morning.
 
I need one of those.
We got super lucky finding this neighborhood. Within about 10 houses on our street there are 7 families with kids ranging from 8 days to 16-17yrs. Most with 2-3 in the house. 4 of us have boats (Yamaha 19ft jet,Berkshire 24ft Tri-Toon, Centurion 24ft Wake, and Chapparel 19ft I/O). It seriously looks like "King of the Hill" on most week nights with a group of 3-4 guys standing around something drinking beer and shooting the breeze.
 
I installed an plug on the swimdeck and onboard charger for 2 batteries (banks). It has been in the "shed" plugged in all winter. The higher charger amperage reduces the charge time.

This charger will split the 12 amps as needed, and once a battery is fully charged the remaining gets all 12 amps. If you only have a single battery you only need a 1 bank charger, or better yet, add a second battery so you have a spare on the water.

Perfect, this looks awesome. It sounds like you can just leave it plugged in until the next time you take it out?

The "BOAT" adage is coming true for me... but because I keep modding lol.

Mine stays plugged in all the time and it keeps the batteries ready to go and over winter. I didn't opt to drill in to the boat again and I just hang the plug over the side and plug it in. It is inside the boat cover protected from elements.
 
I’d like to see how two batteries can be mounted in the 210 Challenger. Suggestions welcome. I’d like to find a dual group 24 battery tray. A dual group 27 tray is easy to find.
