Question about A409FA laptop battery ( From internet ):

Why do A409FA laptop batteries degrade so fast?

The more you use your A409FAbattery the quicker it loses its "charge."  Batteries have a limited number of "cycles" (or charges and discharges).  This number used to be in the low 100s about five years ago, but is now reaching the point of almost 1000.

Honestly, if you use your battery regularly, I would expect it to lat as long as yours has.  It's sort of just the expense involved with using a laptop regularly.  Think of it like your car: Parts wear out.

It's a problem that scientists have struggled to solve because they couldn't figure out what was causing such sudden and rapid battery deterioration.

But now researchers at the US Department of Energy have identified why rechargeable batteries lose their ability to hold a charge over time.

Working with lithium-ion batteries, which are the most commonly used type of battery in consumer devices, the researchers were able to map their charge and discharge process down to a few billionths of a metre to find exactly how degradation occurs.

Their research appears in a pair of studies published by Nature Communications, and according to Matt Safford at Smithsonian Magazine, two main culprits in battery degradation were identified:

"The first: microscopic vulnerabilities in the structure of the battery material steer the lithium ions haphazardly through the cell, eroding the battery in seemingly random ways, much like rust spreads across imperfections in steel.

In the second study, focused on finding the best balance between voltage, storage capacity and maximum charge cycles, researchers not only found similar issues with the ion flow, but also tiny accumulations of nano-scale crystals left behind by chemical reactions, which cause the flow of ions to become even more irregular after each charge."

Running batteries at higher voltages also led to more ion path irregularities, and thus a more rapidly deteriorating battery."

We should expect to replace A409FA laptop battery every 1-2 years. If it lasts longer, that's great, but I would anticipate replacing it around then.

How do I check whether A409FA laptop battery is dead or not?

  1. Press F8 when booting up your A409FA laptop.
  2. At the bottom after the booting options, there will be a system diagnostics.
  3. After selecting that, your system will automatically check the proper working of every part (hardware) of your laptop.
  4. That should do it.

    To be safe, try disconnecting and then connecting the battery again before the diagnostics.
