Battery for the post 2000 Chetak is woefully described in the owners manual as 12V-9AH. This is too generic a description to locate the proper battery. Most riders recommend the Yuasa brand. The more specific descriptors are provided below:
Generic battery: 12N9-4B-1 9Ah
Yuasa: Yb9b
Parts Unlimited: rcb-9b
Exide: 12MX9-B
Note: these are regular lead acid batteries priced at $30-$60. Many riders have tried to use AGM (sealed) batteries only to find the dimensions do not fit the battery box on the Chetak.
Recommendation: Use the former bajajusa owner's trick of petroleum jelly on the battery terminals and you will never have battery post corrosion problem.
