optima batteries

Red top or yellow top for a modified. Thanks

[washeduptoo]

We use a yellow top in our mod.

I think they're way overpriced and not any better than any other battery. JMO

Red -

IMHO
optima batteries seem to take the charging every week better .... regular car batteries will last a long time but , unless you buy a deep cycle type, Regular batteries are not made to be "run down" to certain voltages and then re-charged... ( these numbers are lower that what a street car does with cranking, then being recharged with the alternator)... so I guess if you run an alternator on your race car ( different thread).... disregard the above ....
Another thing that I have heard over the many years of replacing regular batteries in race cars, was the vibration and sudden stops and hits and movement.... moves the plates around in regular batteries and if they touch, the battery will short out internally.....

I have one now thats 3 years old how often should they be replaced. Thanks

We have been using the reds for years with no problems.

I have a blue top optima I've had it for 6 years now and it was used when I got it at a swapmeet. best 75 bucks I've spent. For my new car I'm running an alt so I'll get a cheep everstart as you can over charge a optima a friend left his charger on high for to long and fried his I'm not going to risk it just yet.

I had nothing but bad luck with the red tops. I switched to a cheap autozone and been fine 4yrs now.

Something to think about.... I believe the red tops are "starting" batteries typically for trolling motors or boats that you will start often. The yellow tops are more deep cycle + starting (a mix). Not sure what the blue top is for. I'm going to run a yellow because of the weight difference between a dry cell and standard deep cycle.

Red is for a street vehicles typically. Yellow is for street vehicles or racing that has a generally higher demand on the battery and it gives more consistent power even while being discharger.
Blue is for marine use such as trolling motors and high accessory (GPS, sonar, fish finder) use as you would see on a boat without an altenator.

The blue is designed for boats, Boat batteries take a beating. Bouncing, impacts on waves, high demand and not consistently charged. Sound familiar? We ran a blue top (which was recommended to us by an optima rep (Said yellow for asphalt oval but the blue would be better for dirt as it was better dampened inside.) and it ran for well over 5 years and was still going.
Not sure why you say without an alternator? more boats have a charging system than do not, heck my 9hp Honda had a battery charger and it is a pull start only.

Yellow for high demand street type cars (Developed for car stereo applications)
Red is for high demand instant power discharge (like starting an engine)
Blue is for more run time and more recharges than other batteries. for boats and RV's.
From the Optima site for the blue top. "On top of providing outstanding vibration resistance, the BLUETOP’s efficient power delivery and faster recharge time mean you’ll spend less time worrying about your battery. This means more time for fun. Again and again. This battery is ideal for those who need a sure-starting, strong-cranking, maintenance-free power source."

He11 I didn't know they had 3 different blue top's.

This will be my 7th year on my yellow top. The only charger i have ever had on it is a $20 motorcycle trickle charger. I take it out of the car every winter and put it in my basement to keep it out of freezing weather. Put charger on it the night before i am gonna race, never had any problems.
