### Does My Motorcycle Have a Gel Cell battery?

Except for a few European bikes such as limited BMW and Ducati models, AGM is the standard battery type. In almost all motorcycles that have sealed batteries, that sealed battery is an AGM, not a Gel. In fact, if you were to find a correctly sized Gel battery, it is very likely that using it in your snowmobile, ATV, or motorcycle will lead to early battery failure. 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...

### 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. more...
