Buying a laptop replacement battery

Factual Questions
1

I’m wary having heard that they you can run into problems. Prices seem to vary from a list of about $180 to $50 on ebay.

My computer is a Dell Inspiron B130 and the current battery says … “rechargeable Li-ion” TYPE HD438 Rating 14.8V Capacity 29WH

Anybody have any advice??

If you’re wary of problems, then I recommend the safest approach, which is to buy the replacement battery from Dell directly, for $135.
