How often should I check it?
-
-
I charged it at 7 amps at 14.5 to 14.7 volts. It took a little while to charge up out of the box about 40 minutes. It didn't stay in full charge for much more than 10 minutes the rest of the time was in the last stage. I kept it on float for about an hour as well.Thanks for the advice.
-
Thanks just checking because I read they can rest at 13.2 and now its at 12.79. Trying to make sure it will be ok to install in the spring time.
-
When my charger said it was done it was resting at 13.22 volts after 4 days it is resting at 12.8 volts is that ok?
-
Depends on the resting voltage when you get it or if it has sat for 6 months. If it is at 12.6 volts or under it needs a refresh charge with a charger that can charge to the performance curve of figure 1.2 in the instructions that came with it.
-
Both are good as with any battery you have to keep them charged up with either a solid enough alt for your project and or a good charger for them. Listening to a 4500ish watt system loud most of the time to where the vehicle is falling apart can yield a bad less than 1 year old stockish battery under the hood that won't charge past 12.4 volts and a 4000+ watt battery with slight ballooning that won't charge past 12.7 when it use to charge up to 13. The system is about 1 year old or a little more. Thinking it has a 3 year warranty but I doubt it would be covered because a ballooning battery is an overcharged battery..
-
Wet cell battery should stay at 12.5 and above and your kinetiks should stay above 12.7 volts. Sounds like the batteries are under charged. Get a charger like a Ctek 7002 and charge the front independently from the rear. That charger is fully regulated for all types of car batteries and can fix some of the bad things that can happen from being under charged.
-
So in regards towards my voltage question, could a bad battery cause the external regulator to act like this? I'm now starting to notice a slight bulge on the top of the battery and there is a tiny crack where the hissing and some fluid (?) Is coming from
thats what happens to a battery that is over charged.
-
If it is left at a low charge it can. When batteries discharge they sulfate and the longer it stays sulfated the harder to recharge they can get. Also the hotter a battery is kept the more it will self discharge.
-
You can not just use the 12 volt post on a 16 volt battery. It has to be charged on the 16v post and it wont charge on 14 volts.
-
12.8 volts to around 13, and buy your self a ctek 7002
-
just get the alt and battery checked, most places do this for free or minimal charge.
-
Wouldnt it be better to put the alt directly to the back batteries and run a ground from the back batteries to the alt bracket?
-
I do plan on getting a HO alt and better starter battery but want to just get this in for now. Next year I'm going to try and add another 15 and another 2200 but I'll double up on electrical then. Just want to get by for now. Hows that battery treating you? Did you get dimming while driving before the Iraggi?
If your alt is going to be on the small side I would opt for a bigger capacity battery. Smaller battery on a smaller alt will get cycled more. Also in that situation I would get a charger to keep the batteries all charged up all the way from time to time.

Wouldn't running the ground up front actually complete the ciruit with the charging system without having to worry about how condutive the materials in the car's construction are? No worry of alloy bolts or poor to no conducting alloy/plastic/rubber pieces in the vehicle.
-
Thats what about 11,300 watts? I would think he would need more alternator and batteries.
-
Are these the Cadence ZRS series amplifiers? If so that is a ton of power for a 240 amp alt.
-
Looks like amazon has some kinetik HC2400's for 277.83 shipped

NO 4 walmart batteries does not match the power of 1 D3100!! Flooded batteries do not operate efficiently in car audio applications. This is like comparing 1980 technology with 2010 technology. Kind of like the Zack Morris cell phone to a IPhone. If WalMart batteries worked so well there would probably be world record holders sponsored by walmart.
I am just using this for an example. All applications and set ups can be different depending on the equipment being used and the set up.
If you have a 5000 watt system with a 250amp alternator (that actually puts out 250amps or more) and one D3100. You are going to have the amperage pull from the vehicle + the amperage pull from the system.......... approx 550amps total. The alternator will provide 250amps, so the batteries must supply about 300amps of power. If you are using the D3100 as your starting battery you will still have enough power to supply the other 300amps of power. Your voltage would drop, but you would still have power. This is playing your system at full tilt. If you are not at full tilt then you would not be pulling that much power.
so the d3100 will provide 300 amps of power longer than 4 group 31 walmarts getting drained 75 amps each? That would be 440 ah @ 300 amps or 75 amps per 110 ah vs 300 amps on a single 110ah d3100. Wouldn't the 4 batteries be less likely to get caught up in a failure or thermal runaway condition? Notices all the answers they give ignore the 300 amps the 1 battery will have to provide even with the engine on.
-
Yes you would get 4 X the walmart performance.
So the 4 walmarts would indeed last longer vs 1 d3100 in a set up with a 200 amp alt and 5000 watt amp?
Just saying if this is based on a 1 or 2 battery system I do not know of many people (if any) with 2 alts running 1 or 2 batteries as you would need 2 250 amp alts to produce 500 amps for the 5000 watts. So for a 5000 watt system with 1 alt it would seem you would run into a low capacity situation just using the 1 d 3100. Wouldn't you run into the same type of situations with 4500 and 4000 watt set ups?
-
Yes, if you have 4 batteries then you 4 times the power to supply to the system. For easy math and a explanation lets say your system was pulling 100 amps from 1 D3100. If you had 4 D3100s it would still pull 100amps, but that 100amps would be divided between the 4 D3100s
So it would be the same for the 4 walmat batteries to right?
-
Faster than what? If you are pulling about 500amps (5000watt system) and only able to produce 200amps from the alternator (approx 50amps going to run the car) you are going to start pulling your battery voltage down.
Right but would the 4 batteries run the system longer without a recharge?

What was the resting voltage of the battery before and after you charged it?
