should I buy one or two? I have a yellow top under the hood and a brand new mechman 270 amp alternator running around 3800 Rms in a daily driver. price is 1 factor but weight as well. these new batts are going in the trunk of my 96 bird. 1 9a31 is 250 and 2 9a34's is roughly 350 (Canada is a lil more pricey than our US bratha's). Weight is about the same between the 2 options, any difference other than size in this equation? 2-34's is a tight squeeze with the available space I have 1-31 fits easily. Also the distributor has the 31's in stock ATM and the 34's are not arriving for a couple weeks.
thx for any reply's of signifigance.
