Just looked up a $1000 example. Here's a "cheaper" one, the second row is 1.7lbs, 220 CCA for $160:
BATTERY SIZING - 12V ( Any voltage available )
Based on your starter cranking current.
Ah^ Wt./lb CCA dimensions $$
2.3 .7 110 4.5 x 1.2 x 3x3 90
4.6 1.7 220 4.5 x 2.2 x 3.3 160*
7.0 2.6 330 4.5 x 3.5 x 3.3 240
9.2 3.5 440 4.5 x 4.8 x 3.3 320
11.5 4.4 550 4.5 x 6.0 x 3.3 400
But for hypermile purposes you would need a "BMS" because, according to the the seller, undercharge events could destroy the battery. I don't know about you, but EOC in the dark is frequent for me in the colder months. Lights and radio run a battery down fast. BMS is $200 more. Pretty pricey battery!
