I may be overstepping regarding this 12 v battery in our Prius but just becauses it doesn't fit in the prearranged slot in the trunk - is no reason to pay such an outrageous price for their air vented battery.
It is a nicely sealed area for the battery but it erks me to see them screwing us on this setup.
I have owned other Toyotas and a group 24 battery was usually the norm.
I have looked in the 12v battery area and it seems to me that there is plenty of room for a bigger battery - but just because it is a Hybrid why can't I use another size battery?
Or are we all suppose to be so rich that it doesn't matter that we are getting screwed?
Anyway, I have a 2008 Prius that I paid $35,000 for because of the grap when gas went up to $4 a gal. It was a real rip off but at the time I decided to buy a Prius with all the bells and whistles.
A battery that last only 4 years is a definite a goof up for this great car - and yet I hear only minor belly aching - With this scientific marvel and a crapy battery seems like a bridge to nowhere.
Whew, now that I got that off my chest - I can now consider whether I want to buy the Optima for $235.09 or try doing my own modifications for a group 24 for about $50 or so. Maybe even 2 or 3 motorcycle batteries in parallel. They are small and more adjustable.
Any suggestions or reasons not to use another type batteries would be welcomed.
A lot of batteries can " sort of fit . Most automotive batteries need high CCA to start an engine , a prius needs a different type of battery , basically a deep cycle battery, as the prius does not have a starter motor , high, CCA is not required , and is of no value
The correct battery , either a oem or equivalent will give you many years service . If you fit a " normal " battery, it will fail after very little service .
Buy the right battery , swallow the bitter price pill , it is well worth it , and much cheaper in the medium and long term.
I have avery second hand 2004 prius , .bought cheap , had to rebuild the main traction battery , and replace the 12 volt battery , and solve other problems, caused by previous owner doing silly things .
My prius is now very reliable , excellent ride and gives me 5.5 liters per 100 klm , which is equivalent to42 .7 US miles per gallon , the engine does not like fully synthetic oil , it runs best on semi synthetic oil. Does not need topping up the engine oil between service .. wonderful car
