The Nintendo DS Lite uses a Lithium Ion rechargeable battery.
It is possible to play your Nintendo DS Lite while the battery is recharging; however, this will cause the charging process to take longer than the typical three hours when the system is not being played at the same time.

How do you know when it is time to change your Nintendo DS Nintendo battery? Can you know? Of course you can! Follow these steps to determine if a Nintendo DS battery needs to be replaced.

1. Ask yourself if the battery is taking longer and longer to charge. If the answer to this question is yes, then you may need to replace your battery. The longer the battery takes to charge, the older it is.

2. Think about how long this battery has been in your Nintendo DS battery battery. Your battery is only good for almost 500 recharges. After that magic number, you will need to replace the battery.

3. Examine the battery. Has the battery been compromised in any way? Is it corroded or leaking? If the battery is damaged, replace it as soon as possible.

4. Has the battery pack gotten wet? If so, get rid of it. Never use a battery pack that has come in contact with a liquid.

5. Consider the battery’s ability to hold a charge. Has the battery been running down more quickly than usual? This is a sign that the battery is getting to the end of its lifespan and it might be time to replace it.

6. Has the battery been exposed to extreme heat or cold? If so, the available charge on the battery will decrease.

7. Look over the above list. Now that you have asked yourself all these questions, you’ll know if you need to replace your battery or not.
