What to Consider When Buying a Car Battery Warmer If you’re in the market for a new car battery warmer, you’ll find that many products look pretty similar online. Here’s what you should keep an eye out for as you shop for the best fit for your vehicle and battery. ### Car Battery Warmers Key FeaturesHeat-Retaining Insulation A battery warmer can’t effectively heat up your car battery if the material it’s made out of loses warmth quickly. You want a product that offers layers of insulation to trap heat around your battery. Whether you’re opting for insulated wraps or wraps with heating pads, insulation (and even reflective insulation to help direct heat better) is key to ensuring your battery’s fluids don’t freeze. #### Adjustable or Customizable Fit Not all car batteries are exactly the same size, which means that not all battery warmers are going to flawlessly fit your specific battery. While you can look for products that are made specifically for the size you need, it’s easier to find ones that are adjustable or customizable. Some battery warmers, for example, can be cut to size. Others feature Velcro or adjustable straps so you can achieve a secure, safe fit. #### Resistant to Oil and Abrasions If there’s one thing your car battery warmer has to be able to do beyond heat up your battery, it’s survive all of the different fluids and potential problems it can encounter under your hood. Oil is one of the most likely contaminants, so make sure to look for a product that’s oil-resistant. And if you’ll be removing your warmer often, you can run into snags, abrasions, and potential tears; this means it’s also a good idea to opt for a product that’s abrasion-resistant and durable. ### Car Battery Warmers Pricing The price of a car battery warmer depends on how feature-filled the product is. If you’re looking for non-electric warmers that increase your battery’s temperature with insulation alone, you can find options priced between $20 and $50. If you’re opting for a car battery warmer that actually heats up and provides electric warmth, you’ll spend between $50 and $100 – though some products can be as expensive as $150. ## FAQs You’ve got questions. *The Drive* has answers! ## Author Heather Fishel is a writer well-versed in subject matter that’s both informative and intriguing.
