Question 1

Does this battery make noise? I hear faint sounds of water being sucked by a straw.

Accepted Answer

This is likely the result of using an Unregulated Transformer-Based Charger (a wall wart style charger). The issue with these are that as current output drops voltage increases. So a charger designed to output 13-14 VDC can put out as much as 18 VDC when current output approaches 0 Amps. The result is electrolysis of the water in the Sealed Lead Acid battery. What you hear is gasses being released from the water inside the battery. In small amounts, the battery is designed to recycle the gasses. Excessive charging like this can destroy the battery. Consider a better controller which regulates voltage to preserve the life of your battery.

Question 2

What kind of hardware do I need to connect to the post of this battery?

Accepted Answer

I’m using my battery for my travel trailer, so I threaded the holes to except a 3/8 bolt so I could hook the eyelet battery cables to the post. You can also use regular car terminals and connect your cables to those.

Question 3

Can I mix this with non deep cycle battery?

Accepted Answer

Unless you separate them - NO!!!!!  Batteries don't mix.  In my RV, I have an engine sealed lead acid battery.  I have two AGM deep cycle batteries.  They are different types.  The manufacturer put a battery isolater in there somewhere, with a momentary switch by the dashboard.  If engine battery is dead, it can get a boost from the house batteries.  However, my house batteries keep draining over time.  Not sure how this all works and if manufacturer used plain ole lead acid batteries originally that matched engine battery, but my AGMs last 1-2 yrs at most currently.  Have to check it out, why that is happening.  I need to totally disconnect engine from house batteries and get a small solar panel to keep engine battery charged up.  I want zero contact between the two systems.  Do not mix.

Question 4

What is the charge level to voltage for this battery?

Accepted Answer

Highest charge voltage 14.8v, float highest is 13.8 volts When measuring the battery after its charged it will rest between 12.8 to 13.1 volts.
