All 054 batteries share two key physical dimensions: 187mm (L) x 127mm (W). The height of each battery varies from 220mm to approximately 226mm. Like most car batteries, they use 12v of power. Yet while they share some physical characteristics, not every 054 battery is the same as the next. When choosing your car battery, there are some important features to consider. Amp-hours (Ah) tell you how many hours your battery is likely to last before recharging becomes necessary. Meanwhile, the more cold cranking amps (CCA) your battery has, the easier it will be to start your car on winter mornings. Please note: Before buying a higher-grade 054 battery, we advise ensuring your engine has the capacity to benefit from the extra CCA it provides. Please contact us for more information.
