Some people say AGM battery need three stage charger. If I use it as start battery, should I wire a charger between alternator and this battery?

Sam.. I use this battery for audio system.. I checked before I used and was fully charged.. It sits at 12.4v.. I use that inside of the vehicle bcuz does make the gas that a wet cell battery will.. So far work rly great it can handle 6000 wtts fine of my subs (also changed my alternator to a 170 amp one)

No, you only need to charge the battery when you receive it and you need a charger that will charge an age battery. The charger only charges 2volts per cell. Anything over that can damage the cells such as a normal battery charger. Xs power, optima and several other companies make am chargers and those also work for lead/acid batteries...you don't need anything to install it in your car except post or screw terminal adapters depending what your car uses

No. The charger is only necessary if you pound your stereo hard at idle or with the car turned off. Once you take the battery below 12.6-12.8 static voltage from usage then it will need charging. If your plan is to put it up front as your starter battery then your completely fine since your alt charge will be enough to keep topping it off.

Yes, you could. But, the life of the battery would be reduced. Agm batteries have special charge requirements. And you would be mixing old and new batteries together. Battery performance can only run as good as the oldest one and would bring the life of the new down to match the older one. All batteries for best results should match type, size, and age. spend an extra $100 and get a good quality charger.

I've read where the agm batt can be charged by this charger when connected in parallel with another conventional battery. I also know that there are agm battery chargers available. I suggest that you look up the charging of the agm on youtube. Someone has probably already solved this type of problem. Cheers.

No. All positive connections to the start battery remain the same, but you can move some accessories from the start batt to the aux batt so when your alternator is not running and you are using accessories, it will not drain your start batt. Hope this was helpful.

This is an AGM battery, an excellent design. To ground your jump starter, first ground by clipping the negative (black) onto a metal engine part or frame, put the positive (red) on your positive terminal. Always connect negative then positive. For jumper cables, use the following pattern positive-negative (jumping vehicle) negative-positive (jumped vehicle). On the jumping battery you will put the negative on the negative battery terminal.As you keep this battery charged and maintained, you should get 4-7 years of life out of it. I recommend a 3 watt solar panel.

Yes you can, but my advice is to let your alternator keep it charged. It'll save time and be more efficient for you.

I haven't used it with an AGM battery, but in my experience the charge topping off followed by float charging sounds perfectly normal. I don't know what the tripping sound is. Maybe I just haven't heard it?

Need to have a smart charger to charge AGM battery. Charger will shut off when battery is charged. Need to charge or get battery maintainer so battery will last long time

From most people I hear in car audio, they say a second battery is not the way to go. Just puts more strain on the alternator. It's better to have 1 big battery, if anything just get a larger battery. I have 4 sets of 3 way components and 12" sub powered by 2 600rms amps. My voltage stays completely stable on a stock alternator with just one of these batteries. Rule of thumb is to take your amps combined RMS wattage and thats what you'll want in a battery.

It probably does, but keep in mind that different batteries require different floating voltage ("maintenance mode" in other words). This charger has no voltage adjustments. For an expensive AGM battery you will want a better charger, the one that would allow voltage regulation, and also has a temperature compensation.

I assume you are talking about two 12v agm batteries hooked in series, that are then connected in parallel to a 24v source. First, battery minder makes a charger for agm batteries vs normal car batteries. Second, to be safe, if there were a way to disconnect the two 12v batteries from each other, and from the 24vsource, you should be able to charge them individually (red clip to + terminal on battery and black clip to a ground point on the vehicle). Do not attempt to charge while connected to 24v source or while the two batteries are connected together.

most battery chargers would charge this sort of battery. to make sure of this, check your charger and see if it will charge an agm battery, if so, your good. secondly, yes you could use a jump box or cables if needed.

The best way to fully charge a deep cycle, especially if not used for auto is to use a 3 stage smart charger....this is the ONLY way to fully charge a deep cycle battery.

Yes, this is intended to remain connected to a battery 24/7 (whether in a car or out of a car) and it begins charging the battery when solar power is available and the battery voltage is 13V or less, then once the battery voltage is raised to 14V (showing it is charged) it will stop the charging. If you will be connecting a solar panel thru a lighter plug in a car (which seems to be the easiest place), I hope the lighter remains "on" without the keys in the ignition (otherwise your "charge" power will not be getting thru to the battery making putting all of this together pointless). If you were to start a car with the panels connected up, the panels may send their rated power to help start the car (during good daylight), but they won't put out any "extra" power (they are not a battery that "store up" power or such, they just give you what they can). Once the car is started, the car alternator should instantly recharge the batteries and the green light on this should instantly come on (showing that solar power is blocked).

You should read the Battery specs. AGM batteries if charged at 12 volt DC only. NOT 12.5 to 14.5 or more, like most chargers. AGM's will take an Unlimited amp charge at 12 volts . Its the charging voltage thats critical with AGM's Check the spec's at Optima's website or any info about AGM's. I have the 1500 model and it charges at 12 volts only. Works fine on any battery AGM ATV's and big Sears Platium Odessy AGM's and brings back to life old trailer lead acid's.

I'm not familiar with this part #. This charger works great for me. It actually works better than the old charger. If you left the battery in the old charger overnight, it would be very warm the next morning. With the new charger , it will be cool, both the battery and charger--this is good for the battery & power bill.

I did not put it on a "charger" because i dont trust the one i have. I just let it sit and build a charge overnight then tightened it up and let the alternator charge on my commute. Not the right way to do it but it worked and registered correctly on the multimete .
