What type of batteries doe this Sony mp3 player use? Does this use AA or AAA batteries, or does it have built in batteries that you just recharge like phone?

A built in battery that can not be owner replaced. With normal use, the battery should last four or five years, longer than most people keep a Walkman.

No this MP3 cannot be charged, it may work while plugged in through USB without batteries, but it wont hold charge if it does not have a battery. It uses one AAA and last a while on it

This ear phone used 2 AAA batteries. The brand I use gives me several days of use.

Sure, friend that uses it has MP3 player that takes AAA batteries, just have to use the provided cable. As other answers provided, this speaker will not charge batteries and will work with any player that has a 3.5 MM plug

Hi there! Rechargeable battery inside this Sony Portable DVD player is not your regular kind of battery. If let say they died out, you will have to send it in for repair for those batteries. -Ely

In actual time, i don't know. But it is as long as any other mp3 player. I and we have had several different ones. Many many songs can be played before a recharge is required. - Jim

It was a gift for my son and I haven't used it. He is very happy with it and reviews on Amazon and other places were very positive. It uses two AAA batteries based on the owners manual I downloaded. NOTE: the manual says NOT TO USE rechargeable batteries.

It takes 2 AAA batteries. I use the rechargables because my daughter uses it constantly! Hope this helps!

Neither. This device is pretty bare bones. It's really just an MP3 player. Micro Sd and standard SD card would be for a smart phone or a tablet (and a Nintendo DS handhelds and certain cameras inexplicably). Not quite for a Walkman.

Batteries are included but use rechargable AAA. One minor drawback is the headphones may need a bit of jiggling to make proper contact on the recharging station. Surprisingly good range from station. Had to replace mine as the swivel area between headband and ear piece broke. Hope this helps.

After fully charging the MP3 player, the batteries will last for approximately 16 hours of playtime. The MP3 player connects directly to your computer's USB port with a USB cable, and does not have a slot for a memory card.

The unit will charge or discharge depending on what it is connected to. If it is connected to a device requiring power, then the batteries supply power to that device. If it is connected to a power source, it will draw power from the source to recharge the batteries (I'm assuming you are using rechargable batteries). For example, I have a portable MP3 player / remote speaker which has its own battery, but its battery lasts only an hour. Using the PortaPower, it will run all night. The MP3 player is not a power source itself despite having its own battery.

It uses a rechargeable Lithium Ion Battery pack. I brought a spare one as a back up and its worth it. You can't use AA or AAA batteries. I am happy as a clam w/ my Nikon S97.

It doesn't have batteries, it's just a headband with little speakers. You attach it to your music device (iPod, etc.)

It is a new version Sony specific USB connector and it will not match up with an older Sony (or anything else). So you can't use your old Sony USB connector to charge this MP3 player, if you have an older version that is. Hope that answers your question.

It runs on USB power or three AAA batteries. There are two cords: one that connects to the headphone outlet for audio, and one that connects to the usb outlet for power.

The device uses AAA size regular alkaline disposable batteries and consumes very low power (they last long time depending the frequency of usage), it does not make a sense to use rechargeable batteries.
