Battery charger

Alternatively, you can take all your measurements and go back inside to analyze them. Take 10 minutes to get everything and then go elsewhere.

Wish I had one, my friends dad is a retired diesel mechanic and he has some VERY nice snap on chargers he lets me use when I need them.

I will say this, if you have an AGM battery, be careful of a charger you get. They can be fickle and get overcharged depending on the charger.

Look at NOCO smart chargers, get one with enough amperage for your entire system's idle current draw.

awesome! thanks dude the walmart near me has them in stock. so you just keep it attached to the battery while you tune?
They're cheap and they work, but not as long as a better charger will, mine crapped out after about a year, the NOCO smart charger is still going after 2 years.

View attachment 306726 this ones a 10 amp, what do you think

and do you just leave it plugged in and connected to the battery while tuning? it won’t overcharge or fry amps?
That's why you want a "smart" charger, just hook it up and tune. Ten amps should be plenty for your system.
I use a G7200, it's an older 7.2 amp, it's a little deficient for my system (9 amp idle current draw), but it gets me by.

This is what I use. Works great, actually bought it for the sole purpose of tuning my truck but now have used it for conditioning friend's batteries and charging

I use these DC power supplies from HP, I have a couple of them. They run at 12.9V-13.0V and they can supply 75A ea and they are 94% efficient.
I agree you don't need a huge amount of current, but I think that 10A might be a little small.


These are used in servers and for bitcoin mining, but they work great as benchtop supplies too.

hm maybe 700 watts full tilt
Helix V8 dsp amp 75w x 8
sub pulls 150w itself

okay yeah i’ve looked at a few power supplies and am completely lost on how you would connect that. is the car battery just completely removed from the equation?

When using a battery charger on your battery while tuning your system check the voltage to make sure it doesn't exceed your amplifier specs. Also make sure the type of battery you have is capable of charged by the charger some chargers won't charge AGM batteries. I will look for a higher amperage charger or something in the marine department that charges multiple types of batteries in a high amperage fast charge setting. Prepare to spend some money but you'll have a great charger from going forward if not a regulated power supply , which is pretty pricey but very effective if you do it often or as a regular thing otherwise I wouldn't spend the money on one.
