It comes with batteries (you knew that) but I don't think you can change them. Usually a battery recharger comes with the ds but if you bought it used that may not be the case. See if you can find it and gaming stores or maybe Radio Shack?
By using a charger waste is reduced since the batteries are rechargeable and do not have to be thrown away.
The Nintendo DS Lite Battery is a Lithium Ion Battery. They are known mainly for their long lifetime compared to other kinds of rechargeable batteries on the market. The Nintendo website claims that it can be recharged upwards of 500 times before running out.
A rechargeable battery makes it work.
Some electronic games do come with chargers where you can plug in the system and wait for it to charge up. PSPs, Nintendo DS, and games similar to these are examples of games that come with chargers. For those games that don't you can go out and purchase your own rechargeable batteries at places like Walmart or stores that carry electronics.
I just looked at Amazon and they have like batteries under 20 dollars or just like under 8 dollars but I'm not for sure it will be work but its useful :)
