Scotty wicn battery should I use in my drag racing car ?Old school guys ron marine . But they dont take a charge as fast. We have to cool the car down quick sometimes . So I have to run fans and electric water pump. I have a altenater but the car isnt ran for very long.Im trying to get away from taking a generater and charger with me . Would lead acid be better?
Lead acid or marine battery
These two are not exclusive. Most marine batteries use lead-acid chemistry. I get the suspicion you mean something else, like flooded cell.
I'm unsure exactly what you're trying to accomplish, or why you don't want an ordinary car battery.
I have a altenater ...
good, well that will charge the battery up in the car
the car isnt ran for very long
so you're saying you need something that will hold a charge? AGM batteries have lower self discharge (1 to 3% per month). These are still lead-acid batteries. Just with different internal construction.
Pros:
- More durable than flooded cell.
- Charge faster
- lower self discharge
- Safer (no spills or gas evolution)
Cons
- Very expensive
- requires different charging program (may need a controller module)
- Heavy (still uses lead)
- 50% discharge limit
Im trying to get away from taking a generater and charger with me
All lead acid batteries (whether they're flooded, agm, sealed, deep cycle, marine,...) have some self discharge, so you probably won't be able to get away from this. My advice would be to get a plain old car battery, but one of those that has a carry handle built into it. Take it home with you and plug it in the garage to keep it charged.
Another option is to use Lithium-ion batteries. They hold their charge for a very long time. However, they have a different voltage, so you would have to find different fans/pumps/charge controllers, or use some kind of conversion circuitry. They're also much lighter (better 1/8 mi. time!). Downsides are that if the battery is damaged in a collision they can burn very violently, spewing hot metal everywhere, and you have to let it just burn up because you can't put it out.
