Lightweight Deka Batteries

Updated on January 22, 2012

The best upgrade one can make to a vehicle is to "add lightness". When decreasing the weight of a vehicle, every aspect of the vehicles performance will improve. Acceleration, braking, handling, fuel economy and part wear rates will all improve. All other factors being equal, a heavy car will eat parts faster than a lighter car.

With modern sports driving enthusiasts and racers, the key to a better vehicle is less weight. There are countless products available which are designed to reduce weight. Things like carbon trunks and hoods, titanium build products, lighter seats and many other things are available. The trick is to decrease weight as inexpensively as possible. This can be via removing non-essential parts, or by purchasing inexpensive parts that have a dramatic effect on weight loss. Batteries are the first place you should look, not wheels, hoods, exhausts or trunks. Factor in cost per pound of weight reduction, and you'll be hard pressed to find something better for your money than a lightweight Deka battery.

Deka Lightweight Batteries

Often, when the discussion of lightweight batteries comes up, people will argue up and down about CCA's, CA's, PCA's, and all those other confusing and often outdated methods used to rate a battery's performance. Lightweight batterys are available from countless companies, with some being extremely expensive, while others are very reasonable. Today, we're going to focus on the reasonable end of the spectrum, with Deka being one of the best when it comes to inexpensive, high performance lightweight batteries. Below is a comprehensive list of the Deka batteries, which features the ratings for each battery help you choose which battery is right for your application. At the bottom of this article, we'll discuss that causes different requirements for batteries to help you make the right choice.

Making sense of battery ratings

Battery ratings can be a real headache to figure out, especially if you're doing it for the first time and can't find a good source of information. Below is a list of the terms and ratings, as well as what they mean.

Cold Cranking Amps (CCA)

The CCA test determines the maximum load that you can apply to a battery for thirty seconds before the battery drops to 7.2 volts. Most modern vehicles would stop trying to turn over past approximately 10 volts, as the electronics that make the engine turn over wouldn't be getting enough power to run. This inludes the start, ECU, ignition and injectors.

Hot Cranking Amps (HCA)

Hot cranking amps is simply the CCA test performed at 32°F. Again, still considered to be an obsolete test with today's electronically powered vehicles.

Amphere Hour (Ah) Ratings

The Ah rating is the batteries horsepower. A battery with a 10 Ampere hour rating could provide ten amps for one hour. 5 amps for two hours, or one amp for ten hours. If you run your sound system or other electronics for significant time while the engine is turned off, the Ampere hour rating is important. Heavier batteries will be able to provide more amps for longer periods between recharging.

An inexpensive alternative

Deka batteries are produced by East Penn Manufactering, and are a great inexpensive alternative to the linkes of Braille and the other more well know manufacturers and re-branders of batteries. An 11.5lb Deka battery has no problems starting a twin turbo 2.6 litre inline six over and over again. At less than one hundred dollars, it's a price that is hard to beat. For a larger car with more cylinders and/or displacement, it would be wise to choose one of the larger Deka batteries, as you want to ensure your car starts easily, every time. The ultry lightweight ETX9 might seem like a great deal, as well as a significant weight savings. But if it can't start your car every time, than it simply is not an effective battery for your application.

When on the market for a Deka brand battery, always make sure you ask the sellers as much information as possible about the battery. It would be wise to contact East Penn Manufacturing directly to ask them what they recommend for you. When in doubt, always contact the manufacturer. They've done the testing and know what model will be right for you!
