Exide has 7Ah MF battery.Replacement for old ZMA with 7Ah Battery.

Mine was also Amco Flooded lead acid 7Ah battery,Replaced it with Amaron 9Ah MF battery with some mods to the battery cage,Now its 6 Months and didnt faced any problem. Have a look at my signature for Installation of 9Ah Battery in my Karizma.

Sealed maintenance free(smf) battery is a class of batteries in which the electrolyte is sealed inside and cannot spill or be replenished . They come mainly in three types here .
i) Ordinary flooded lead acid type .. in which the battery vents are sealed/semi-sealed preventing spillage only .
ii) gel type . Electrolyte is absorbed in a chemical gel .
iii) agm type . Electrolyte is absorbed in a glass-mat .
Type ii and iii are also known as acid starved types . Additionally they have various venting systems and recombinant catalysts .
Amaron's Pro-biker/Quanta-plus is sealed AGM( absorbed glass mat ) and VLRA( valve regulated lead acid ) kind , catalyst assisted recombinant inside to recombine H & O released inside partly back into water . The valve will vent if the pressure inside rises to more than 1.5 bar owing to gassing .
Smf is a misnomer really , because they are not totally maintenance free but low maintenance . You still have to keep them properly charged at all times .

Yes , batteries are a confusing subject .. I know that as I am in charge of maintaining several small and medium battery systems in UPS and generator cranker .
Basically as I found , some older bike's RR units do not produce well regulated currents/amps needed for smf(agm-vlra) batteries . So the charging voltage goes above 14.7+ volts sometimes at higher rpms . This will cause gassing inside an smf battery . i.e Loss of electrolyte which cannot be replenished because it is sealed . i.e shorter life .
I do not know about the CBZ(2003) RR .. it may well be able to cope with new battery type ... or not . Before fitting amaron pro-biker , test (from battery dealer if possible) if your regulator/alternator combi is producing voltages in the range 12.5-14 volts steadily at correct amps for the battery .

Aneesh / psr 's bike's alternator/RR are robust units build much more recently and known to produce well regulated current/voltages . Moreover even a poorly charged/maintained battery will perform well for a year in a bike . We have to watch aneesh's for more than 2 years . Smf amaron battery will also cost roughly twice as much as the SF Sonic I mentioned . I always fit my older bikes with their OE type and maintain it .

The last time I tried in Chennai only flooded type and not MF 7 AH was available in the Exide range.They further clarified MF is available in 6 AH,model ETZ-7. The Amaron 9 AH requires larger charging current, to attain fully charged condition.

The RR in my ZMA is heating up after installation of Amaron 9 AH, and I had already fitted a thick Aluminum sheet double folded for more heat absorption and dissipation...I had for test purpose run the bike without battery ,in the night with headlight,brake lights etc., to give max load to RR and generator...at that time i had noticed RR getting hot,so had fixed the heat sink.
You can test by running with the 9 AH battery in the night with light for 5 Kms and then open the seat and touch the RR.

The 2011 ZMA comes with a larger RR and runs much cooler.

hi, sorry for asking help here, my query is also regarding amaron battery thats why i post here instead of making new topic. (if it breach any policy please move to right section please..)

i want to buy amaron 9ah battery for my bike but unfortunately we dont have any dealer / seller here(im from dhaka, bangladesh). it would be so helpful if any one can send it over here with courier service(dhl,fedex, ems) and i will pay with paypal masspay or wu whichever you prefer..

thanks again

Nrutt bhai , battery is very heavy so postage cost will be very high , moreover since it's acid filled item I doubt if courier will carry . And what about warranty . Better buy battery from your place only IMHO .

thanks Pinaki bhai for your thought..actually im ok if it cost within 3000 INR, i think it could be done with india post ems service? Welcome to the Indiapost Web Site

and its just a battery(is it drycell?) so hopefully there shouldnt be any issue with the courier ..do you think you can help me with it?

regards

Guys i've finally given upon Amaron Dry cell cuz it would fit with lot of pains and hassles and chances of RR unit heating up on a higher side.Finally i've found out about Rocket batteries and its also available in 7Ah and is MF Dry cell.Cost is about 1500/- with 24months warranty.
One of our local shopkeeper told me that not to install dry cell in cbz classic cuz it would create problems so its best to go for wet ones.Is this true??

Should i go for Rocket dry cell??

As I said earlier , sometimes charging units in older bikes are not able to maintain correct charging levels necessary for SMF(agm-vrla) batteries . I am not sure if classic cbz is able to or not , but this battery type is finicky about charging current & voltages . It would surely appear so if this shopkeeper is speaking from experience . It would be best to stick to wet(flooded-cell) type battery that came OEM with the bike , unless you have some special requirement to fit another type .
Check is SFSonic battery is available in your place , it is an exide made brand with low cost and very good performance . They also have full range of capacities for motorcycles .
