Thanx Noor for the approval

Guess you have 7Ah battery,Amaron have no 7Ah battery,You can fix the 9Ah battery with some mods to existing battery cage. Have a look at my signature,I had fixed 9Ah Amaron in my ZMA. Guess it will be same in your bike too.

The original equipment battery for your bike was flooded-lead-acid type , I believe . Are you using the same type , or changed to the new sealed-maintenance-free types ?

@pinaki

It's the same acid type one.The reason i wanna go for Amaron Dry cell cuz it's maintenance free.Current one is giving me too many problems.

Wats a maintenance free battery and how much does one from amaron cost?

they are sealed and dont need to be topped up with distilled water every 4-5 months . amaron ones cost around 1450 rs for the 9ampere one

True,.... the Lead Acid battery with Flooded type needs attention like top up with distilled water and cleaning terminals and applying white petroleum jelly to avoid corrosion etc.,apart from this maintenance ,the acid spill from battery also causes corrosion on parts coming in contact with it..
So it is better to switch to Sealed Maintenance Free Battery.
Amaron SMF comes in 2.5, 5 , 9 and higher amperes with 24 months replacement + 24 months discounted replacement depending on no of months in use..There is no 6 or 7 amps type..Exide makes SMF 6 amps widely used in ZMA-R /ZMR /CBR250 etc., and the model no is ETZ-7

The amaron battery (maintenance free) is the best battery out there.
I am using it for more than a year.
Believe it or not, this battery can take a lot of stress, it never gives up.

I've initially bought it for DC conversion, and many many things went wrong in it.
So the battery had to go through extensive overcharging/undercharging and also was the most stressed part of the bike from the beginning.

Later after the installation of the Alternator, the battery had to do everything, it even had to run 100w hid bulb as well as run the spark plug all at the same time, not to mention every remaining electrical on the bike, the battery still didn't give up until a good time.
However now the battery has taken a toll, but that too after the most vigorous R&D for more than 1 & a 1/2 year.
Just go for this battery eyes closed, its worth more than the money you put in it.

Besides, you can install a 5 amp battery too, it would still make the self start work, or go for 9 amps and modify the brackets.
Any mech would be able to do this for you anyways...

+1, absolutely true...

i am using the amron probiker series dry sealed type, maintainance free.
i have been using it fir the last 1 year and never faced the problem of low battery. on cold mornings, i have to crank up the engine 5-8 times before it starts still the battery holds on fine.
on top of this, i have the 5 year free replacement warranty... so even of the battery lasts 3 years after such abuse, i would be happy to buy a new battery of the same type... :P

Absolutely ROCKRZ
Even i have a 5 year one (60 month one), its basically 2 and a 1/2 year replacement, and the remaining pro rata.
But I've heard that lately, the company is only providing the 48 month one.
Its still is enough and much better than the competition...

OK guys now coming back to the topic!! What should i do?? Should i do the jugaad that Aneesh has suggested?? Or should i go for Exide ETZ-7 SMF 6amp?? Cost??

Physically making the battery fit is one problem Aneesh has solved ,SMF battery like the Amaron pro-biker (AGM-VLRA) is very good one , myself using it in various applications . But you should understand what battery goes well with your bike's electrical system . If your bike came with flooded lead-acid type battery as OE , your RR may/may-not be able to charge up a smf type battery of higher amp-hr rating correctly/adequately/fast enough . This is the only weakness of batteries of this type , they are very particular about the charging voltage and currents . Undercharging / overcharging /deep discharge / charging with higher or lower voltage or amps / keeping in discharged condition /operating in high temps etc kills them early .Flooded lead-acid type is very forgiving of charging currents and operating conditions because the electrolyte in them can be replenished .
Unless you have some special need for smf battery / extra power etc and can verify that the RR and electricals on the original CBZ(2003) can take care of smf type & extra amps .... buy original flooded type in the same capacity as OE . SF Sonic rodeo is a good cheap battery in the correct size & capacity for your bike made by exide . Check the electrolyte levels , top-up if necessary with distilled water and full charge it - monthly .. and it'll last a very long time .

@pinaki

Bro im gettin confused now.Now y cant SMF type batteries charge properly on the bikes that came with flooded lead acid ones as OE??

@Aneesh

Did ur Karizma come with a Flooded lead acid battery as OE?? Hw's the battery(Amaron) performing in ur bike?? Feedbacks plzz
