Deep cycle battery preferences?

Mono is between Orangeville and Shelburne.

Other words,he,s in the boonies. It was about 25 years ago anyways.LOL

 

Just stay away from Trojan. They have to be the worse piece of crap battery I have ever bought. They burn up, way to fast.

What do you mean by "it's way down in it's capacity"? There are several factors that impact a starting batteries performance including it's age and it's state of charge (voltage). If you are discharging your starting battery more tahn 10% on a regular basis your batteries life is going to be greatly shortened.

If all the cells are bubbling it's a sign of possible overcharging. If only 1 cell is bubbling than the battery likely has a dead cell or is on it's way to developing a dead cell and should be covered under warranty. You may want to pick yourself up a hydrometer at Crappy Tire and measure the specific gravity of the electrolyte in each cell. If the variation between the highest and lowest cell reading is 50 gravity points or more you probably have a failing cell. (The battery should be at least 12.45 volts before testing with a hydrometer.)

Hope that helps.

 

My cranking battery is brand new (2 months) as I got it with my new motor. It's down to a 9.9 volt reading on it, until I put the juice to the motor and then it goes up to 13.8.

 

As for the deep cycle I will be checking into the warrenty. It's only 2 cells that are bubbling over. I am using the same charger and charging the same way I always do.

A fully charged battery has a voltage of 12.65 and is 100% discharged at 11.89 so if your starting voltage before the juice is 9.9 you obviously have an issue. You usually see a voltage that low if the battery has been sitting a looong time without a charge. Try charging it with an external charger 5 amps for 20 hours and then retest the voltage.
