Do I Need A New Car Battery
Posted in Car Batteries | Asked on Jun 24, 2010
I have a 2000 Honda CRV and am installing different electrical Components but am worried about the battery. I am currently running all the factory things plus a 150W amp and a JVC 4X50W deck. I want to also run a mobile charger, ipod charger, GPS charger mini fridge and maybe possibly another amp in a few months.
I currently only have the standard battery that comes with the car (liquid CCA 400 RC 60). Will this work everything and constantly recharge of the alternator or do I need a second battery?
Also should I just buy a Optimum dry battery seeing as it will do the job and is cheaper?

Its always advisible to turn on the car and then play your music system, In that case you need not change the battery.
My advise is to try it the way it is. If it is not working then buy an Optima battery.
Everything should be fine, doesn’t sound like it would put a strain on your battery or alternator.
a 150 watts doesn’t consume too many amperes, maybe 30-50,
nor does a headunit (radio) – 5 amps
those chargers.. probably 1-3 ampere each.
as for the mini-fridge, i’m not sure, maybe another 30-50
That’s approximately 70-110 amps of extra load over the stock electrical load. That should really do anything.
If there is dimming of the lights, the first thing I would suggest is doing the “Big Three Upgrade”. This will help with the power being distributed throughout your vehicle.
