NAPA car battery charger

Every battery posts the amperage ratings on the top label. This tells you how much power the battery is capable of providing.One of the most overlooked upgrades is your vehicle’s battery. While the type of battery under the hood is not likely to give you any horsepower gains, it will save you from having to get jump started in the middle of the night at the gas station. Additionally, a properly functioning battery means your alternator doesn’t have to work as hard, and getting the best performance from your charging system is always good bet, especially if you have upgraded electronics. This guide is here to help you on your next trip to pick up a battery. You will learn which one to grab and which ones to leave on the shelf.

Amperage Ratings

  • Cranking Amps (CA) – the rating of cranking amperage measured at 32 degrees F.
  • Cold Cranking Amps (CCA) – the amperage rating the battery can provide at 0-degrees F for 30 seconds without dropping below 7.2 volts. This is the most important measure of a battery, and is the typical rating used for selecting the appropriate battery for a vehicle.
  • Reserve Capacity (RC) – measured in minutes, this is how long the battery will provide 25 amps until the battery voltage drops to 10.5 volts.The other side of the label tells you the type of battery and usually features a purchase date selection used for warranty purposes. This is used on both starting and deep cycle batteries.
  • Amp Hour (AH) – typically used for deep-cycle batteries, this illustrates the amperage capacity. A battery with 150 amp hours rating would provide 15 amps for 10 hours, 10 amps for 15 hours or 150 amps for 1 hour.

Battery Types

While most batteries are of the same age-old lead acid (LA) design, there are many ways to put them together. The main types are flooded, gel and AGM (Absorbed Glass Mat). All lead acid batteries use the same overall concept – lead plates (one is lead, the other is lead oxide) are submerged in an electrolyte solution of sulfuric acid. Each of these plate groups is called a cell; a group of individual cells is called a “battery”. As the battery discharges, the lead electrodes become lead sulfate, and the electrolyte dissolves into water. This why batteries freeze during the winter, which can cause the lead plates to touch (short-circuit), effectively destroying the battery. While charging a lead acid battery, through electrolysis, the battery generates oxygen and hydrogen gas, which can be explosive, which is why batteries are typically mounted under the hood, where they dissipate and do not become condensed.A typical flooded battery has caps on the top for the water. Some are one-time fill, others are serviceable. When installing a battery in the trunk, a firewall must be installed to protect the passengers; the battery box must also be vented to the exterior of the vehicle.

  • Flooded – This is the most common type of LA battery but there are couple subgroups – conventional and sealed. Sealed flooded battery are designed to be maintenance—free, meaning you don’t have to add water at any time, they are sealed. Within a conventional battery, such as a “tar-top” battery in a classic car, each LA cell is separated and each group has its own electrolyte. Over time, the process of charging and discharging uses up the electrolyte and it has to be replaced with distilled water. Some modern batteries still require this kind of maintenance.
  • Gel– The platform is the same, but instead of using plain old water as the base for the electrolyte, they use a thickened version (like Jell-O) to keep the electrolyte from leaking in the event of a cracked or broken box. This also makes the battery more stable in terms of vibration and installation location, as the gel doesn’t move, which ensures the plates are always covered in electrolyte.Replacing your battery should begin with removing the ground terminal. This helps reduce the chances of arcing to the body when removing the positive terminal. One of the drawbacks for gel cell batteries is that they are more susceptible to voltage irregularities and they can’t be refilled, once the electrolyte degrades, the battery is toast.
  • AGM – AGM or Absorbed Glass Mat batteries are the most efficient of the lead-acid design. AGM batteries use a fiberglass separator to keep the electrolyte between the lead plates. This makes AGM style batteries extremely stable in any position, even upside down. NAPA offers an AGM type battery in the Legend series, which uses a flat-plate core with AGM electrolyte separators, making it impossible for the plates to touch. These batteries last much longer than a conventional or gel-cell battery, and are the superior design for wet-acid type vehicle batteries. AGM batteries also resist freezing longer than conventional batteries.

Both gel and AGM batteries de-gas like flooded batteries, but since they are sealed, the gasses are reabsorbed into the electrolyte, keeping them functional longer. Both types of batteries can release their charge faster than flooded batteries, which is an important function. In order to provide a larger level of cranking amperage, a flooded battery must be much larger, as a typical flooded battery is limited in how much charge it can release at one time. Gel and AGM batteries can release more charge at once. This means that gel cell and AGM batteries can fit in a smaller case while providing more amperage.

Battery Subclasses: Starting and Deep-Cycle

  • Starting batteries – have higher cranking amps for heavy, short bursts of energy use a larger number of thinner plates to release more amperage. The thinner the plate, the more amps is can release in a burst. The side effect of this is that the plates get hotter faster, which causes them to warp and pit, particularly when they are fully discharged.
  • Deep-cycle batteries – use fewer plates, but each plate is thicker, so they store more energy, but can’t release it as fast, only 25% of the rated amperage can be released at one burst. Deep cycle batteries are used for long-term constant draw situations, such as boats, golf carts and show cars (lights and stereo systems).
Now is the time to access your battery wires and terminals. The bolt for the ground terminal on this car was rounded off. A pair of pliers works great for removing the bolt from the molded wire end. The new bolt is a perfect fit and will tighten up nicely. A loose terminal can mimic a bad battery, so always check your terminals first. When installing the new battery, start with the positive terminal.
