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...

Why is My 12 Volt Battery Reading as 13 Volts?

All Lead acid batteries (Gel, AGM, Flooded, Drycell, etc) are made up of a series of 2.2 volt cells that are bridged together in series to reach their final desired voltage. more...

When Should I Add Extra Sulfuric Acid to my Battery?

When you see your battery acid level begin to drop, you may wonder when and if it is appropriate to add acid, or just water. We recommend that unless a battery was tipped over and all the acid spilled out, that you add only distilled water. 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...

Calculator | Sizing a 12 Volt Battery to a Load

Do you need a 12 volt battery for your application but don't know what size? This calculator is designed to help you find a deep cycle battery when a continuous load is applied, not for cranking or starting purposes. If you know how much power your application takes to run, and the time you would like to run it, we'll recommend a 12 volt battery with a safe amount of AH (Amp Hours) that will give you the run time you need. 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...
