need some help with all those tech jargon, how to decipher the following spec, like, what is B, LS, Ah, CCA, and how should I choose?
55B24LS - 45 Ah, 430 CCA
How to choose you ask ? Use back the same specs as the one in your car now or manufacturer recommendations.
Anyway I cannot really decipher the early part except that's normally the size, voltage, plates, etc coding
The LS is probably to tell you the terminal orientation, which is left/right to correspond to your car design terminal leads
45Ah is 45 Ah the capacity rating of the battery, i.e it can deliver 45A for 1 hour.. so if you only use 1A, the battery can theoretically last 45 hours
430 CCA is the cold cranking current rating, how much current the battery can deliver in cold weather to start the motor, i.e winter
since the most current drawn is when starting the motor when cold.
Anyway, probably better battery expert lurking around LYN and wait for a reply from them if any.
