Re: 12V racing battery recommendations
 
I used to run the optima batteries because they would last forever but they weigh a ton! Recently switched to the Odyssey batteries and have been really happy so far.

I found out about them from some off road friends and they are really rugged and dependable.
And they are extremely light weight.
A couple of my customers have switched to them with great results. https://shop.antigravitybatteries.co...extreme-power/
I ordered the Antigravity! Thank you Tom!

I received an email for 8% off if you enter "8offaug" this month.
Interesting. This is the battery I use in my PWC. Does it have enough power to run the fan and water pump for a decent amount of time?

I think you will be happy with it .
Just be sure to follow the charging instructions.
Like any battery ,proper charging rate and voltages are key to longevity.

Sounds like you and I have exactly the same battery experience, Larry. This is the 4th season on my two 11.5 lb Braille batteries. I even completely killed them once last year by leaving the water pump on for 5 hours...discovered this fact when they called us up for first round. Charged them for 15 minutes or so, the car started, and I still beat a few people to the lanes.

A few years ago my car wouldn't start for the semi finals at a race and I decided that this was not going to happen again.
Now between rounds I run the fan and water pump from the (2) deep cycle batteries in the trailer normally for the winch and jack. I run 4 ga cables to a switch box and then 4 way cable to a 4 pole plug. The 4 way socket in the car is wired in parallel to the normal wires.

Re: 12V racing battery recommendations
 
Made 13 passes Saturday with a single Group 31 in the trunk, 105amp GM alternator supplying the juice, never had my charger out. Doubt there are many cars using as much power as mine:

Dual stock GM F-Body fans, over 20 amps each.
Mezier electric water pump.
Weldon EFI fuel pump.
8 injectors, though they take very little.
4 coil packs (DIS waste fire setup, like a GN).
The last two hours ran the electric fan on the 2nd trans cooler, not sure what it draws.

The last 6 passes were made 15 minutes between each, only got to the trailer for fuel.

So....... Why mess with these little batteries you have to worry about charging when there are massive batteries out there that will never give you an issue?

Re: 12V racing battery recommendations
 
I run one or two Walmart budget batteries (either 26 or 56 as I recall)
that weigh 26 Lbs. I have been for 25 years. Easy to exchange on the
road if needed. They have recently gone up to $49.95.
I do charge them in the latter rounds.
