I have used Yusa and Interstate batteries. They a good batteries. I scored Interstate for $19.99 and Yuasa for $36 from a battery supply store back in Harrisburg, PA. They cost near $50 where I am now, so I opted for the $25 Walmart battery. Note: for the battery kits (where you charge them) that you need a battery charger. I own a Battery Tender Junior.
The secret to maintaining and extending the life of your battery is to ride frequently and often or use a "float" charger, because float charger turn off and do not over charge.
The batteries which work for your Bajaj are:
Generic battery: 12N9-4B-1 9Ah
Parts Unlimited: rcb-9b

I've heard many times the starter eats up a lot of battery juice; hence it is recommended you use the kick start instead.
If you are not riding at least three times per week, you will find the battery is not being recharged quickly enough, which will result in a short life. To combat this it is wise for you to invest in a "float" charger (shuts off automatically and does not overcharge like a "trickle" charger does, which could also destroy your battery). I have owned three and am the most happy with the "Battery Tender Jr.", which I bought via Amazon for the best price I could find.
If you are riding often, it's a good idea to plug into the charger once per month and fully recharge your battery. A quality $50 battery should last 3-5 years and with a float charger used properly, definitely 5 years.
