Bigger battery

HI i must change battery on a 2005 rav4, stock battery size i think is 35 but id like to put a 24f size, i need a lot of CCA where i live, stock battery was barely enough powerful (even when car was new) when it is below -30C

do you know if battery will fit easily, battery is just about 1.5 inch wider.
thanx

Agree on tiny batteries. For a while it seemed like they kept getting smaller every year. I always replaced them with the biggest one that would fit, sometimes removing tiny plastic trays. I'd go to Walmart, Autozone or whoever has a good selection, measure them and put in the highest CCA that will physically fit. Don't forget to measure height. Maybe someone with a 4.2 has that answer, but nothing beats confirming it yourself.

It's the pedal (or the handgrip) on the right!!

Costco has the 24F for 75+tax.
Is 640 CCA enough for you? It comes with 3-year replacement and 100 prorated warranty.

Agreed, measure the maximum height/depth/width and look for max CCA.

Yes in this case bigger is better.

You can go a lot bigger if your willing to relocate the connector.

The link is to my blog, scroll down and you will see the monster 35 size I shoe horned in.

Its a marine battery but the CCA is plenty to turn over my engine even when its -8F

I use the marine battery so it serves double duty as a deep cycle that powers a tiny refrigerator. Its a great system.

im actually looking into a battery as well but for a differant reason. I plan on installing a higher end sound system and was looking for advice on a few things. I know i will need an isolater but for the actually second battery i was thinking about an optima. any thoughts on something like this?

The second battery will be strictly for the stereo and a few Led's i will be installing as well

currently driving a 01

It's a lot easier to ask for forgiveness than permission...... It takes weeks to get the ok for the nerf bars...... it only takes 12 roses to get back into the bedroom

What is the advantage of installing a second battery? The charging system should be able to handle your planned upgrades, a second battery would still require charging and would not increase the vehicle's charging capacity or its ability to take care of the additional electrical load, would add weight (reduce mileage and affect vehicle handling), require finding a location and affixing mounting hardware, require cabling, take up space which could be used for other purposes, and there would be the cost to purchase it . . .

May be you are planning to run your stereo with the car off for a long time?
Otherwise, I also don't see why you would need a second battery.

He can do several things with an extra battery.
Locate it near the high power amp for a more stable power source.
An Optima is completely sealed so it can be mounted anywhere in any position.
A battery isolator prevents the extra battery from discharging the main battery. That could leave you stranded.

Maybe a single Optima (Red) will solve the OP problems rather than going larger. I have a yellow one in another vehicle with an undersized issue. I went yellow rather than red because that car never needs to start below 50 F. In that case the accessory and parasitic load were the problems. Expensive, but it solved the problem.
