Charging a battery without an indicator

3 posts in this topic

I did a search and couldn't find anything so if this is an over asked question forgive me. I just bought a battery and charger combo from Cabelas and they came with no charging instructions and no charging indicator light. The battery is the usual 7 amp, 12 volt. The charger is 12 volt, 500mA. I am assuming that means it is a 1/2 amp charger. If that is the case it would take 14 hours to charge a totally dead battery. If I am wrong please correct me and any input on charging and upkeep would be appreciated. confused.gif

Here's an excerpt from the instructions that came with my battery:

12v gel cell batter charging (from Ertl 12v, 7.0ah instruction sheet)

For maximum battery life, batteries should be:

· Stored at 50 degrees or lower. Life is shortened considerably at temperatures above 85 degrees.

· Charge according to proper procedures. Continuous over or under charging does the most damage. Recharge as soon as possible after each use. Recharge every 6-9 months when not in use.

Charging:

· Be sure to disconnect the battery from the locator before charging.

· Just after disconnecting a charger, a reading of 14.5v to 15v will indicate a full charge.

· Peak performance will come from a battery that holds a charge between 13.5v and 13.8v after being given time to “settle” (usually takes 5-10 minutes after charging).

· If not using a voltmeter, general rule is to charge the battery for ¼ the time it was used (assuming started from a full charge).

· DO NOT OVERCHARGE!. It will ruin the battery in as little as a few hours.

Hope that helps!

      I'm wondering the same thing!  Low temps have been dropping below freezing and in shallow water that temp has to drop multiple degrees in a night.  I'm wondering if they went back to the breaks and are waiting again?

      Public water is the Surface of the Water, not the land beneath it.  So even if you can access the river through an easement the actual land that youre standing on could be private property. Everything on the DNR Website says "Surface of Water" in the trespassing section.  I agree this is unfortunate,  but as usual, the 3 drunk morons that don't care ruin it for the 1000 that do..... standard procedure these days.  1 idiot doesn't clean his boat, and wrecks a lake for thousands of people.
