  • Battery Basics: A Layman's Guide to Batteries
    If you’ve done any research on how batteries work or what you should look for when selecting a battery, you’re probably buried in information, some of which is conflicting. At BatteryStuff, we aim to clear that up a bit.

    You’ve most likely heard the term KISS (Keep It Simple, Stupid). I’m going to attempt to explain how lead acid batteries work and what they need, without burying you with a bunch of needless technical data. I have found that battery data will vary somewhat from manufacturer to manufacturer, so I will do my best to boil that data down. This means I may generalize a bit, while staying true to purpose. read more
  • Battery Bank Tutorial: Joining Batteries Via Series or Parallel for Increased Power
    What is a bank of batteries? No, it’s not some kind of financial battery establishment. A battery bank is the result of joining two or more batteries together for a single application. What does this accomplish? Well, by connecting batteries, you can increase the voltage, amperage, or both. When you need more power, instead of getting yourself a massive super tanker of an RV battery for example, you can construct a battery bank. read more
  • What Does “20 Amp Hr Rate” Mean?
    Several years ago when you would go to buy a car, the little tag on the window of a coupe might have read 42 mpg. Of course everyone knew that the only way to make that car get 42 miles to the gallon was to drive at 25 miles per hour on a newly paved level track. So in 2008 when the EPA updated their standards, the ratings all dropped to much more realistic numbers that most light footed people can achieve. Battery ratings are very similar. The faster a battery is drained, the less overall amperage is available. The battery’s AH rating goes down the faster you use it. read more
  • Gel vs AGM: Not Quite the Battle of the Ages, But Nice to Know
    More often than not AGM Batteries are mistakenly identified as Gel Cell Batteries. Both batteries have similar traits; such as being non spillable, deep cycle, may be mounted in any position, low self discharge, safe for use in limited ventilation areas, and may be transported via Air or Ground safely without special handling. read more
  • Make the Bad Sulfation Go Away!
    Sulfation (sul-fay-shun), the number one cause of early battery failures, can be safely reversed, using high frequency electronic pulses. Unlike other pulse type chargers that claim this or similar sounding features, VDC's BatteryMINDers® use a range of high frequencies. This ensures both old and newly formed sulfation will be safely dissolved in the shortest possible time. Using just one fixed frequency may remove some, but not all, especially long established–hardened sulfate crystals. read more
  • How Do Batteries Die? Well, Let Me Tell You...
    Approximately 50% of premature car battery failures is caused by the loss of water for normal recharging charging due to the lack of maintenance, evaporation from high under hood heat, or overcharging. Approximately 85% of premature deep cycle and starting batteries failures that are not recharged on a regular basis is due to an accumulation of sulfation. read more
  • The Super Secret Workings of a Lead Acid Battery Explained
    A 12-volt motorcycle battery is made up of a plastic case containing six cells. Each cell is made up of a set of positive and negative plates immersed in a dilute sulfuric acid solution known as electrolyte, and each cell has a voltage of around 2.1 volts when fully charged. The six cells are connected together to produce a fully charged battery of about 12.6 volts. That's great, but how does sticking lead plates into sulfuric acid produce electricity? read more
  • Troubleshooting a Battery
    One of the facts of life is that batteries fail. Some take years, but eventually they will all bite the dust. However, there are so many factors in electrical systems that can go wrong, that often times the battery takes the blame for other component's problems. The easiest and fastest thing to check for problems is the battery. Here is a simple test that can tell you a lot about what is going on inside a battery, and whether it is good or not. This is not meant to test anything other than the battery, but it is a great place to start if you are having electrical problems. read more
  • Lithium Iron FAQ

  • Proper Care and Feeding: NiMH Battery FAQs
    What does NiMH stand for?
    The material is Nickel Metal Hydride (NiMH) which has many advantages over other battery construction materials.

    What is meant by battery memory?
    Older generation and batteries with other chemical make-up were subject to a memory effect. This is when a battery must be fully drained before recharge or their capacity is reduced. The New Generation of NIMH batteries do not develop a memory effect and can be recharged at anytime during usage cycle. When uncertain about battery charge level or condition, recharge it. read more

  • Peukert’s Law | A Nerd’s Attempt to Explain Battery Capacity
    When I first entered the arena of lead acid batteries and their neurotic tendencies, it was presented to me that the easiest way to rate and understand how long a lead-acid battery would last, would be to use the AH (Amp Hour) rating that is so often designated to them. I was told that if a battery was rated at 100AH, then that was more or less indicative that it would last either 100 hours under a 1 amp load, or 1 hour under a 100 amp load. It soon became apparent that this notion of order was false; everything previously understood had been a lie. read more
  • What is the Difference Between the Terminal Type F1 and F2?
    The SLA batteries we sell, up to 12 volts 15 Amp Hours (AH), commonly use the faston tabs as the terminal type. The F1 and the F2 are the terms we use to refer to the terminals. At first glance, they look very similar. These are flat blade type terminals which stick up at an angle from the top or side of the battery. These terminal types are designed to be attached with a push-on spade insert, either for your application or for charging. The F1 terminal is thinner, and the F2 is wider. read more

  • OK, Who's Got Gas? Fuel, That Is.
    The first thing you must understand about today's fuels is that the environment is the first consideration and the engine performance comes second. The Environmental Protection Agency (EPA) plays a heavy hand in today's Gasoline and Diesel fuels development. read more
  • PRI-G FAQ and Dramatic Benefits
    By comparison, gasoline today is initially much cleaner than gasoline sold 10 or 20 years ago when it is first produced. However, today’s fuels are less stable today because they are produced through cracking processes versus the less efficient “straight-run” processes used years ago. As a result, today’s fuels deteriorate at much faster rates - resulting in excessive carbon build-up in your engine. Given the varying length of time it takes for fuel to be consumed after refining, it is wise to freshen fuels every tank full with PRI-G to ensure maximum combustion and performance. read more
  • Cooling Tutorial
    Years ago environmental required cleaner burning engines and thus engine operating temperatures were raised in order to reduce exhaust emissions. Today's engines run on the borderline of overheating.

    We have found that many people neglect their cooling systems until it becomes a costly problem. A properly maintained cooling system will provide excellent service for many years. There is more to maintenance than just changing the antifreeze every two years. Little things like replacing hoses and keeping the air flow clean and unobstructed are also very important. read more

  • PRI-D FAQ and Dramatic Benefits
    Given the fact that literally thousands of fuel additives are offered on the market, engine manufacturers have no way of monitoring or testing the claims of so many products - making it difficult to determine specific products that are safe to use. However, PRI chemistry does not alter any fuel specifications issued by engine manufacturers - specifications by which manufacturers judge whether or not a particular fuel affects safe engine operation. PRI has been safely used in thousands of engine types. read more
