History Commercially working batteries had become widely used after their invention in the early 19th century, but they had many drawbacks. The electrolyte was a liquid acid which meant the casing was usually glass, making them relatively delicate, heavy and hazardous if they broke or spilled. They were robust enough…
In the commercial battery world two technologies are mixed up more than any other – Absorbent Glass Matt and Gel. Even some leading battery websites hold misinformation on what they are and what they are best suited for. Both are referred to as Sealed Lead Acid batteries but they have…

From Benjamin Franklin’s tinkering with glass jars in 1749 to cells so small and flexible they can be integrated within a credit card. The history of the battery has been one of invention and innovation. However, it has not always been this way. Wikipedia defines it as one of ‘successive…
There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. In the graphics we’ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types….

Deep cycle batteries (also often called Leisure or Marine batteries) are designed to provide a constant current over several hours compared to starter batteries which offer high power for several seconds. Some battery types, such as lithium ion batteries, are only deep cycle and so are not labelled as such….
You may need to calculate the lithium metal content (or lithium equivalent content) of a lithium battery to determine how it should be shipped or to ensure you conform to regulations regarding air travel with lithium batteries. This applies to lithium metal batteries (disposable) and lithium ion batteries (rechargeable). Enter…
You may need to know the watt hour (Wh) rating of a lithium battery to determine how it should be shipped or to ensure you conform to regulations regarding air travel with lithium batteries. This applies to lithium metal batteries (disposable) and lithium ion batteries (rechargeable). If your lithium battery…
Lithium batteries are so called because the metal they originally used as plates is lithium based as apposed to, for example, lead in lead acid batteries. For disposable lithium batteries this is still true and hence they are known as lithium metal batteries. In the rechargeable version these plates have actually…
