Estando em processo de escolher bateria para um Alfa Romeo 1600 Gt Junior, não sabia que tipo de bateria melhor se adaptava, procurei na internet e encontrei na Automotive Electric Handbook da HP Books resposta para as minhas duvidas.
Fiquei a saber que para este carro a bateria deve ter um mínimo de 100 CCA e 60Ah a garantia é o item que pode fazer toda a diferença no preço final.
Transcrevo parte do artigo para este fórum, que se adapta a todo o tipo de automóveis.
As minhas desculpas pelo facto de se encontrar em Ingles

"selecting a suitable battery for your project car is much more than just getting the right price. Once you understand the theory behind battery ratings you need to know how to translate that theory into a buying decision. The following guidlines will help:
Cranking capacity (CCA) is the single most important factor. The rule of thumb is to buy a battery with at least 1 amp of cold crank rating for each cubic inch of engine displacement (1 cubic inch = 16,4 cubic centimeter). This translates to a minimum of 6 amp per 0,1 liter, considering there are approximately 61 cubic inches per liter. For example , a 1.6 - liter stock VW engine requires a battery rated at 96 cold crank amp CCA,. Because most replacement batteries are sold for engines with larger displacements, you may have trouble finding a battery rated this low. In other words, you probably won't have to worry about any battery, whatever the price, being inadequate for a stock VW engine. For larger engines, use the above rule.Then there's a rule of thumb for determining reserve capacity (Ah ampere hour). Unless you frequently travel in remote areas, choose a battery whose reserve capacity permits you to drive the car with a failed generator for at least 1hour (60 Ah) Then there's the matter of warranty. Because the price of a battery is roughly proporcional to its warranty coverage."
