1957 Chevrolet Bel Air Battery
With so many people using Bel Airs in so many different ways, it shouldn't be a surprise that Bel Air owners have at least seven different OPTIMA battery upgrades to choose from. These choices come in a variety of sizes (D34/78, D34, D75/25, 25, 34/78, 34 and 75/25) and terminal configurations between REDTOPs and YELLOWTOPs. Which one is right for your Bel Air? Read on!
In terms of factory engine options, all of these OPTIMA batteries offer more than enough cranking amps to get your engine started. If you have an aftermarket engine, just make sure the battery you choose meets the engine specifications for cranking amps. If your Bel Air is relatively stock from an electrical standpoint, REDTOPs are great options. They tend to be slightly less expensive than their YELLOWTOP counterparts and are slightly lighter than YELLOWTOPs of the same group size.
If your Bel Air has been significantly modified or upgraded from an electrical standpoint, then a YELLOWTOP designed for both engine starting and deep cycle use is the right choice. These modifications could include dash cams, car alarms, air ride suspensions, aftermarket stereos and auxiliary lighting. The same is true if your Bel Air has an underdrive pulley or no charging system at all (typically found in drag racing applications).
Whatever battery you end up choosing for your Bel Air, make sure to keep the voltage properly maintained whenever the car is not being used. We know virtually no Bel Airs are daily drivers anymore, so make a point of getting a quality battery maintainer connected to your Bel Air and use it. We're so confident proper voltage maintenance will not only maximize battery performance, but extend battery lifespan, that we will add an additional year of free replacement warranty coverage to your OPTIMA battery, if you buy an OPTIMA D1200+ battery charger from us when you make your OPTIMA battery purchase!
