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. more...

How to Pick the Right Battery Charger

There are certainly other factors in selecting a battery charger, and it would be difficult to cover them all, but here a few. Input voltage, generally for use foreign countries. Exposure to elements, i.e. would you benefit from a waterproof charger? Perhaps you will need a charger that doubles as a power supply for a RV or some other application. Often people will need to charge multiple batteries simultaneously, so multiple bank chargers may be needed. more...

Testing Your Battery for Parasitic Load

To check if something is draining your battery while your bike is turned off you need to test for current, not volts. To do so, you may need to use a multimeter. Do not start the engine of your vehicle when testing for parasitic drain. more...

Solar Info: The Down Low on Everything Up High

Rain or shine we get a huge number of calls about solar power each day. We’ll attempt to answer the questions asked most often so we can save you a phone call. more...

Do I Need a Special Battery for My ATV with a Winch?

The short answer is that Powersports batteries are just not designed to handle the amp draw of a winch. They are not made for deep cycling, only for starting. That being said, in the real world we have winches. Having a higher CCA is a bit helpful, but what you really want is higher storage amps, and a battery capable of deep cycle. more...

How Do I Keep My RV Battery Charged When in Storage?

If your starting battery is going dead in about a month while you vehicle is in storage, it would be fair to assume you are using about 60-75 amps(typical RV sized starting battery) in that period. To break it down further, we can assume 2-3 amps per day. more...

Solar Panel Installation Tips

BatteryStuff Solar Panels use high quality Poly-Crystalline solar cells. Diodes contained within the junction box insure reliable operation and no drain during low light conditions. Anodized aluminum frames add strength and durability to the modules. Includes pre-drilled mounting holes. The modules have a 20-year, 80% power output warranty. more...

Calculator | Determine Run Time for Specific Load

This calculator is intended to help you figure out how long your lead-acid (Wet, AGM, Gel) battery will last under a specified load. In order to use this calculator you will need two separate AH ratings, given by the manufacturer, as well as the amperage, in direct current of your load. For an explanation of why a calculator is necessary to figure out the true run time of your battery see Puekert’s Law. more...

Math Behind the Magic

Here are the formulas our calculators take into consideration while computing. What? You thought we would show our work step by step? You’re welcome to do it longhand if you like, but personally, I like my calculators better. 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. more...

List of Common Battery Case Sizes by BCI Group Number

Are you looking for a marine, RV, automotive, or solar PV battery? You may have heard common terms like a "group 24 battery" or "type 27 marine battery". These BCI Group Numbers define the physical dimensions of the battery case. This is important as some applications call for specific case sizes. The BCI does not determine the Amp Hours (AH) rating for the batteries, however, but there is a correlation between case size and AH rating. For deep cycle batteries, the larger the case size the more capacity the battery will usually have. more...
