How do! 
Does anyone have any info that could help please. I think the battery on my car (Fiesta ST) may need replacing soon. Starting is sometimes a bit iffy, and the battery in the car is the original. So that has been in 3 years now.
I read awhile ago about light weight Varley Red Top batteries. I'm just wondering what one I would need for my car? All the info on the site means nothing to me.
For example, this is what I found about the Red Top 15 from another site....
Varley Red-top 15 racing battery.
C/10 Capacity: 14Ah
Terminations: M6 Male
Weight: 5.0Kg
Dimensions (mm) L x W x H: 200 x 77 x 140
Cranking current @ 20°C for 5 secs: 550A
However, the Capacity is very low, I think normal batteries are ~40Ah. Is this something to take note of? The cranking current seems nice and high though... is this important?
Thanks for any help or advice! Are these batteries a good choice, or should I just go to Halfords?
Cheers!
