Entertainment while engine is off

If the battery is rated 40AH and your load is 5 amperes, you will have an 8hours play time before the battery is totally discharged. To be safe, you can have a playtime of 4 hours to reserve enough AH to start the engine. Remaining available Ampere-Hour rating of the battery decreases as it becomes older.
Battery is considered totally discharged if the terminal voltage falls down to 10.5 Volts.

Optima's go for 10K and up more or less, a 1SM Outlast should go for around 3K more or less.

Good Read about batteries (Deep Cycle and Normal Lead-Acid car batteries

Basically the biggest difference is that a Deep Cycle Battery is designed to withstand several hundred Discharge/Recharge Cycles that a Normal Lead-Acid can't do.

I wouldn't recommend listening to the radio with your engine off using a normal battery, it would be a hassle not being able to start your car even tho you have jumper cables. Well if your battery is still under warranty you could always call up motolite and have them deliver a warranty replacement or a new battery

for additional information, the cost of a 1SM battery ranges from 2200-2800, depending on the brand and variant. saw it sa minerva tire gallery last weekend.

OT: para makatipid ako (sa gas and sa battery as well), I just bring a good book to read o kaya PSP na lang.

think of it this way, yung matitipid mo sa gas, mapupunta pag pagpalit ng battery, so either way gagastos ka pa rin.

Agreed. Was that the yellowtop? Deep cycle diba?

would installing a capacitor for your sound system have an effect on running your sounds while the engine is off? I currently have a 1-farad installed and I can run my sounds at around an hour to one hour and a half. thanks. I;m just a newbie here. =)

IMO its doesn't, your sound system will still draw current from your batteries.

Bro, Ni-Cad ba yung Optima? Mas matibay ang Ni-Cad kaysa Lead Acid.

Say you want to use your car setup like a open trunk party or picnic while engine is off.. can you use a portable 12V battery charger and charge your battery? of course the portable charger need 220V supply. Will it work? it wont damage any electrical component of the car? TIA
