Welcome to a laptop battery specialist
of the Apple Laptop Battery
The world's first commercial laptop—though that is certainly stretching the term—was the Osborne 1. When released in 1981, it cost $1,795, weighed 10.7kg (23.5lbs), and ran an operating system called CP/M. The 1983 Compaq Portable, which ran MS-DOS, was even larger (13kg) and cost $3,590. Neither had a battery, though an aftermarket battery with like Compaq 100680-001 Battery, Compaq PP2060 Battery, Compaq Presario 1400 Battery, Compaq Presario R3158 Battery, Compaq Presario 1700 Battery, Compaq Armada E500 Battery, Compaq EVO N100 battery, Compaq Evo N1020V battery, Compaq Evo N1000C battery, Compaq Evo N115 batteryfor the Osborne 1 lasted an hour.
At the time, neither of these computers were actually called "laptops"; they were portables that, in a pinch, could be lugged around. Famously, the Osborne 1 was advertised as being the first computer to fit under an airplane seat. Both the Osborne 1 and Compaq Portable were massively successful, raking in millions of dollars from users who realised that portable computing was about to alter the fabric of society and its ways of doing business forever.
We've come a long way since then.
Pick up your laptop. Actually, scratch that—read this paragraph first, then pick up your laptop. You are holding one of the most advanced machines ever built in the history of humanity. It is the result of trillions of hours of R&D over tens of thousands of years. It contains so many advanced components that there isn't a single person on the planet who knows how to make the entire thing from scratch. It is perhaps surprising to think of your laptop as the pinnacle of human endeavour, but that doesn't make it any less true: we are living in the information age, after all, and our tool for working with that information is the computer.
Okay, you can put your laptop back down. Look at that dazzling display, with pixels so small that you can only see them if you get your nose right up against the glass. That unibody chassis, just a few millimetres thick, is remarkably rigid; really, try flexing it. Deep within, there's a single chip that has more processing power than a mid-'90s supercomputer that cost millions of dollars. You have enough ports and chips and antennas to provide gigabits of wired and wireless connectivity.
All of that, though, is nothing without a battery. Smartwatches, smartphones, tablets, laptops: they are all ultimately slaves of electricity. Without power, without a reliable surge of electrons, a device is nothing more than a pretty paperweight.
