Default Better battery for M800?

Anyone knows if we can do any mods and fit a bigger battery in a M800? I heard that a Honda City battery can be fit with slight modifications? What are the pros and cons?

Hi,

Sure, it can be done. You just need to be able to fit a larger battery inside. Why would you like to do this?

Pros - if you are having lots of electrical accessories, then it would possibly help
Cons - cant think of any

Well I have 2 amplifiers, 1 subwoofer, 100/90 halogens and A/C is on most of the times, so I was advised for a bigger battery because my engine doesnt crank sometimes (I currently have a 1 year old Exide battery). The battery guys said that my battery is fine but the load is high so it doesnt crank sometimes.

Which battery should I go in for?

You should probably switch off all electrical accessories while cranking. That should help.

Which amps and sub do you have ?
Right now how much amp battery do you have ?
Just check the width,length and height and than ask battery dealer to give you battery with more amp capacity but same size.

I currently have 35amp Exide battery, the dealer told me that I can go in for Honda City's battery (45 amps) with a slight modification to the 'battery holder box'

he said it would cost 5.5k. will it really help me?

With so much of electrical load, you will need to invest in an alternator with larger capacity too, as I feel your existing alternator cannot take the electrical load and be able to charge the battery.

Why dont you reduce the un-necessary load?

Which 45 amp model ? What is the prize of current 35 amp battery ?

if you can reduce the load than do not spend for battery.

Heard of Amaron? That "last-long-really-long" jig ain't for fun. It's actually true.

Go for an Amaron ultra (48 month warranty). 45 amps should be fine, although with the accessories that you mentioned, you'd probably require 50. Alternator change isn't required, unless you run all your accessories with the engine off, frequently.

First off, is yours an MPFi? If yes, be careful about cranking the engine with a weak battery. Not good.

I am planning to get a better battery this weekend. Any suggestions on which model I should buy? 45 amp or 55 amp? Exide or Amaron or Panasonic?

Upgrade from 35 to 45 amp is not good better go for 50-60 amps and Amaron is best bat.
