A replacement battery is failing. What is causing it?

I replaced the original battery after 4 years of extended use. I replaced it with an identical battery, but I noticed the battery was manufactured 6 years ago. Well, it won't hold a charge any better than the original one. I suspect a power circuit.

I doubt there's a thing worth doing to it for more than the sake of the cost of the songs on it ($900). Otherwise, a technician would charge more than the resale value of the MP3. I appreciate the response. It was encouraging to factor in something other than 'pure bot'.

If you have replaced the original battery with an identical one, but it is still failing to hold a charge, there could be several possible causes for this issue:

  1. Battery degradation: Over time, lithium-ion batteries naturally degrade, losing their capacity to hold a charge. If the original battery had already experienced significant degradation after 4 years of extended use, it's possible that the replacement battery, even if identical, may have also degraded due to its age. In this case, the battery's performance would not be significantly improved.
  2. Faulty replacement battery: While rare, it's possible that the replacement battery itself is defective. Even though it's the same model, it may have been improperly stored or handled, leading to premature degradation or other issues. In such cases, the battery would not perform as expected.
  3. Power circuit issues: You mentioned suspecting a power circuit issue, which is also a valid concern. If there are problems with the power circuitry within the device, it can impact the battery's charging and discharging capabilities. This could result in a battery that fails to hold a charge, even with a new replacement.

To determine the specific cause of the battery failure, you can consider the following steps:

  1. Test the battery: If possible, try using the replacement battery in another compatible device or try a different battery in your device. This will help determine if the issue lies with the battery itself or with the device's power circuitry.
  2. Check the device's power circuitry: If you suspect a power circuit issue, it's advisable to have the device inspected by a professional technician. They can examine the power circuitry, including charging components and connections, to identify any potential faults or malfunctions.
  3. Consider software factors: In some cases, software issues or settings can affect battery performance. Ensure that your device is running the latest software updates and check for any power-related settings or apps that could be draining the battery excessively.

Ultimately, it may be necessary to consult a professional technician or contact the device manufacturer's support for further assistance. They can provide specific guidance based on the device model and help diagnose and resolve any underlying issues causing the battery to fail.

To be honest, I'm leaning toward the replacement battery having outlived its shelf life. Li-Ion batteries don't do all that well when they've been sitting on a shelf for years without being charged. If it was me, I'd go look for an aftermarket replacement; there's a lot less chance that it's been sitting for years and the aftermarket ones are generally of reasonable quality.

Here's one that looks like it's the same part that was being replaced in this video: How to take apart a SONY Walkman NW-E393 NW-E394 NW-E395 and change battery - YouTube

Yeah, if it was mine I'd look at another replacement before I started down that difficult road of trying to diagnose excessive power draw. It's always possible you got a bad battery; it happens.

It's my belief that certain MP3 batteries are no longer being manufactured after the original lot has been sold. The same holds for certain motorcycle brands (cause I own a 2003 Honda). Thanks.
