Charging batteries while in car

[Sable Nave]

So I have two batteries and I would like to keep them constantly charged, but my question is do I need to remove them from my car when I charge them and if not do I at least need to unhook my wires or is it safe to charge with everything hooked up?

you can charge with them in car still hooked up. But you wouldnt want to charge them 24/7, they will overcharge.

Do you have a trickle charger or smart charger?

Don't have one yet, I'm not sure what kind to get with a multiple battery setup. If I can get one with multiple outputs that would be nice, but don't have any knowledge on chargers

i charge them while still hooked up in my car...as long as your car is off... i dont see any problems it can cause... on a trickle for approx 6 hours every once in a while...

Okay cool. What kind of charger do you have?

I use an AGM smart charger because I use XS power AGM batteries. Works fine for 10 batteries, they are all connected in parallel anyway.

So it depends on your batteries.

I have two wet cell batteries from batteries plus, and one is under the hood other is behind my seat. so would i just need to put the charger on one and it will charge the other?

i would just use a trickle charger. its just easier in my oppinion. But you can just hook them up in your vehicle, thats what i did before i got my trickle charger. Didnt cause any problems for me

if the back battery is connected to the alternator or the front batt, then they will both charge, just like from the alternator.

But I wouldnt leave wet cell batteries charge unattended. Maybe have a small battery maintainer but they are really only for when the car is parked a long time.

Do you only drive the car on weekends? If its a daily driver, there is no need to do this.

No, I drive it every day, but I always play my system full tilt when I drive it, and sometimes even when its off. My voltage at idle used to be 14.6, and now its 12.9 so I need something done I think
