Prius replacement
Best battery you will ever own.
Smaller, newer cars don't need a lot of cold cranking amps. If this battery will last for 10 years, it might be worth the price for the smaller cars. If you have an older V8, then maybe you need the CCA that this battery can deliver.
450 CCA is low for the price.
Great batteries, don't get the point of only 450CCA.
i might get this and find an inverter to finally get a backup system for my sump pump
RE: only 450 CCA, the point is batteries come in different size groups so OEMs can put a battery no larger than necessary in a vehicle. Also, any SLA battery that can be further deep cycled will have a lower CCA to volume ratio, it's a design trade off.
Get the size group meant for your vehicle, this Optima part # is not some kind of universal replacement... and #6, you'd be paying extra for the vibration resistance compared to buying a standard deep cycle battery for use with a sump pump. IIRC, my backup sump pump battery was close to twice the size for little more than half the cost.
At the very least, you should buy a replacement battery with the same or better CCA rating as your old battery or one that meets the vehicle manufacturer's requirements. For most small four-cylinder engines, this would be a 450 CCA or larger battery, for a six cylinder application, a 550 CCA or larger battery, and for a V8 a 650 CCA or larger battery. Bigger is usually better. Extra battery capacity is recommended if your vehicle has a lot of electrical accessories such as air conditioning, power windows, seats, electric rear defogger, etc.
I have been using these batteries exclusively on my handicap Van/T & C. If you buy them by mail order, how do you get warranty service? You can't. You have to ship it back to the original vendor. Check out the website of the manufacturer they cover this. Moreover, the ordinary car batteries made by this company have like a 7 year warranty. Only one (full no-cost replacement) or two years for the deep cycle. Better to get the car battery locally and to get back if it fails. On the other hand, I bought my last one, deep cycle, from Amazon and my stupid van has drained it dead many times and it keeps going, taking a full charge. I got one of those expensive tiny battery conditioners made for this type of battery.

Check out the website of the manufacturer they cover this. Moreover, the ordinary car batteries made by this company have like a five year warranty. Maybe longer. Only one or two years for the deep cycle. Better to get the car battery locally and just swap it out.

Don't know why Ben quoted this particular battery. As dave_c says its a popular replacement for the Prius's 12V auxiliary battery altho the terminals do not perfectly match.
Anyway, I suspect the $50 off deal applies to many things at Advance. If not they have a broad $30 off $150 which then comes with a $50 off certificate by mail. Big problem is that $50 expires in about a month.
