There are generally two things to consider when buying batteries. One is the size/shape of the battery (e.g. AA, AAA, C, D, etc.) and the other is the technology that powers the battery.

Most devices only accept one size of battery anyway, so though it’s important to get the right size, it’s not normally something you have to give a lot of thought to. Even so, there’s still the choice of what sort of battery you should buy, and that’s what we’ll explain here.

(This answer also covers “why unfinalised DVD doesn’t play on my DVD player”)

As mentioned in part 1 of our series on laser and LED printers and toner cartridges, toner is the powdery substance that is used to build up the image on laser printers. It comes in large cartridges, which either contain the toner on its own, or combine the toner reservoir with a disposable print drum. (Having the drum and cartridge together does mean that you get a new, high-quality drum each time, but it also increases the price.)

Toner cartridges (including laser toner, LED toner, photocopier toner and laser fax toner cartridges) do cost significantly more than most inkjet cartridges, but they also last much longer, generally in the thousands or even tens of thousands of pages, rather than the low hundreds.

Computer cables- if you’re even slightly like us, you’d probably like to see less of them. They get in the way, look untidy, and (if you have more than a few of them) they have an unpleasant tendency to get jumbled up into a spaghetti-like rat’s nest. Unfortunately, until someone comes along with the perfect solution to replacing them all, we’re going to have to live with them. Read on for everything you need to know about the little blighters!
