All too often searches for information on how you can 3D print a battery doesn’t turn up the answer you would expect. This popular YouTube video, for example, is only about printing the battery case. The rest needs to be put together in the same sort of way that all…
Super-capacitors are nothing new. General Electric was trying out their potential in the 1950’s, but the press today has suddenly become hot with stories that this technology will change the way we store power forever. There has even been speculation that batteries as we know them will never be the…
In our constant drive to reduce global warming and climate change we see wind, sea and solar power as possible solutions, but they have not been as successful as many would have us believe in reducing our carbon footprint. Do new advances in battery technology provide “the missing piece”? Are…
How long did your last disposable battery last? “Not long enough” is probably your answer. So what would you say if you knew that tucked away in a British University, covered by two glass domes to muffle its incessant ringing, is a bell that has been chiming since 1840 ……
The speed in which Sealed Lead Acid (SLA) rechargeable batteries can charge is based on the type of charger you are using, how much of a charge is left in the battery itself and if the battery is still functional and has not exceeded its life. Typically, the larger…

Ah, Ampere Hour or Amp Hour all describe the same characteristic of a battery – how long it will last when connected to the item it is powering. This is often referred to as the ‘capacity‘ of a battery. The measurement is often misunderstood as, for example, “a 5Ah battery…
See Primary Batteries.
Cell – the basic building block of a battery. Batteries can contain just a single cell or multiple cells. Batteries are often referred to as cells and a single cell as a battery (even though technically this is incorrect). A cell is made up of a cathode and an anode…
Batteries in a Series – A group of batteries or cells with the positive terminal of one battery (or cell) connected to the negative terminal of another battery (or cell). This increases the overall voltage while keeping the capacity (amperage) the same. When connected in series the voltage of each…
