Dual Pro Charger Flashing Red on one of the Banks

Swapped the leads of two batteries and the flashing went to the other bank. Anything I can check before replacing the battery?

Bad battery I have had that happen 3 times with my charger every time I take the battery in to autozone it has been bad.

That's what I figured. This battery is only a year old. It's an Interstate. Wonder if they have a warranty or something.

Also, are you supposed to leave your charger plugged in all the time?

Interstate would be under warranty
I keep mine plugged in

Depends on the charger on if you should leave it plugged in all the time.

Most have 2 year warranty... Call (469) 221-4500 and they can help you just like they did me...

Charge the bad battery with a regular charger. If a battery gets to low the on board charger will not charge it..

Hook up the bad battery to a regular chatger and see if it will recharge. If it trips your regular charger it has a bad cell and needs to be replaced. I have had 2 Interstates go bad on me in the year I have had them. Will be looking to replace with something different next time.

Battery is charging fine at Autozone. Fingers crossed that it was too low for the on board to charge.

Your problem is Interstate batteries! Gave up on them a long time ago!

I have never had a problem with the interstate battery....once you get it charged a little put the on board charger back on to see if everything is good to go. It should be fine,it has happened to me several times.

I think you wrong on this one! If the onboard charger want charge it what makes you think any other charger would charge it?

^^^^^^^^^^^^^this

Not wrong - trust me call dual pro and ask them

The charger is junk then.

They are all that way...see owners manuals

Dual pro chargers are far from junk. And he is correct they will not barge a battery that is totally dead.

Minn kota is the same....lets just help this guy with his issue and move on...

Battery is completely charged and good per Autozone. I'll throw it in the boat tomorrow morning and report back for those keeping score.

No score to keep as long as you are up and running.

Mine has done the same thing twice. Both times it was a bad battery.

You can also take a set of jumper cables from the good battery to the bad battery, that will trick the charger.

mine was blinking red it was the fuse

Battery is in the boat and the charger is reading it. Hopefully all is well.

Don't let your battery get that low dual pro will not kick in recharge every time you get off then unplug when done then give it a quick charge before you go the night before also check your water.

Ok, so the battery on bank 3 was yesterday. Today the battery on bank 2 will only charge to 20% and just sits there. A different charger says it is 95% but it is a piece of [censored] from Walmart. Any ideas?

new batteries and keep your boat plugged in and this will be over.

Any onboard charger will not pick up a battery that is below 7v. More than likely your batteries sat so long with out a charge they are smoked anyways. Batteries are cheaper than the headache you are going thru.

Check the fuse connections, those things are [censored], usually
