Yes, it sounds like you need a new battery. These types of rechargeable batteries are designed for a certain number of recharge cycles.
so i should buy a new battery than here is what system profiler say about the battery.

Yes, it seems like the battery has reached its cycle limit. Here's one source, assuming I have the type of PowerBook right.
Based on the battery status you posted, note the full charge capacity and the cycle count. When a lithium battery goes bad, one indicator is that it logs silly values. So, for example, the full charge capacity should be around 3800mAh, and cycle count could be in the 300+ range. As Kenichi Watanabe suggested, a new battery is in order, and OWC is a good source. I've bought several batteries from them for our Powerbooks, and they have performed well.
