Every once in a while we get questions from our customers asking to define some of the terms that they find on their battery. So here is a short list of some of the more common terms and their definitions.
Volt – This is a measure of electrical potential. The volt is named after Alessandro Volta [...]

I know I ranted a bit the other day about the prices that are constantly going up and up. I was reminded again when I had 2 more pages of price increases cross my desk today. Lead seems to be stabilizing a bit however the costs in the electrolyte, fiberglass separator, even the polystyrene/polypropylene casing [...]

The “AH” that you see on most batteries stands for amp-hour. What this basically means is one amp for one hour, or 10 amps for 1/10 of an hour and so forth. It is amps X hours. If you have something that pulls 20 amps, and you use it for 20 minutes, then the amp-hours [...]

I know this can be a bit confusing as the abbreviations to these are CA and CCA, respectively. Now the cranking amps (CA) are frequently called marine cranking amps (MCA) to add a little to the confusion. What the difference boils down to:
-Cold Cranking Amps are how many amps the battery can maintain for 30 [...]

What is a CCA? What are Cold Cranking Amps? These are questions we get frequently here at Batteryweb.com. Let me see if I can clarify a bit. The cold cranking ampere (CCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 0°F until the battery voltage [...]

Free warning this will be a bit of a rant more than anything else. As with most things right now prices are going up. There are several reasons for this, both factual and conjecture.
One fact that is undeniable is the fact that a year ago lead was under 50 cents a pound and is now [...]

Every time we swing by a gas station we all get a bit of sticker shock. Every where you look you see higher prices on gas. News and radio mention the soaring prices expected this spring.
Well NASA has found another source of our much loved and precious oil, on Saturn’s moon Titan. NASA announced the [...]

I am a frequent reader of the website www.eeTimes.com. It is an interesting site that has various information about upcoming technology.
Today I was reading about some lithium-ion batteries that seem to have not been made with the best of quality control. Apparently, AT&T bought some batteries from the now defunct Avestor. So far, 4 of [...]

The supercapacitor resembles a regular capacitor with the exception that it offers very high capacitance in a small package. Energy storage is by means of static charge rather than of an electro-chemical process that is inherent to the battery. Applying a voltage differential on the positive and negative plates charges the supercapacitor.
This concept is similar [...]

The lead-acid battery was invented by a French physician named Gaston Planté in 1859. Lead-Acid was the first commercial rechargeable battery. Today, flooded lead-acid batteries hold the primary position in automobiles, forklifts, and UPS systems for computers. In the mid 70’s, researchers developed a maintenance-free lead-acid battery that can be operated in any position. The [...]
