What I was told is that the numbers 24,27, 31 all mean dimensions of battery. I just took out 2 27's That were 140 hr reserve, lasted 4 years. Hope this helps
Yes...that is correct....but... the bigger the battery dimensions....the bigger the plates and also more plates and more acid....which equals more reserve amp hrs. or capacity.
