Small Batteries

[guest1406]

Hi all,

Coming near to the electrics of the bike and need to think of battery box and battery. Whats the smallest or just small batteries around? I know the antigravity ones are teenie weenie but they have to be shipped and are £70ish. I dont mind them being a bit bigger.

Bike is a Suzuki GN250

Cheers Guys,

Mackenzie

Aye Mackenzie,

The 'Bad Penny' raises its head again! 

Have a look on this site: Goffy's_vehicle_electrics

Click on 'red blob' to the left of the items you wish to select, text clicking doesn't select!

May I suggest "Motorcycle batteries", these are all 'Absorbed glass mat' construction, including a 12v or 6v battery with a box to fit it in, if you have a machine requiring a 6v battery.

Some of the LED stuff may be of use to you and others, if you are not worried about "originality".

My regards, Bill

Just bare in mind you can't go too small as it will still need enough umph to turn the starter over - no kicker on the GN as I recall. I think the original was about 12amp/h so that may limit your choice a bit.

would this work below? I really am awful with electrics.

WESTCO 6V AGM BATTERY

These use the same advanced AGM technology as the 12V batteries above but are intended for use with 6V non-electric start bikes

They have a large 13AH capacity

They are 105 x 70 x 140MM & are a snug fit inside the rubber battery boxes.

(4 1/8" x 2 3/4" x 5 1/2" app.)

Cheers,

Mackenzie

Nope, the GN250 has 12 volt electrics.

How about .. .

WESTCO 12V AGM BATTERY

These use the same advanced AGM technology as the batteries above but are intended for use with 12V non-electric start bikes

They have a 5AH capacity

They are 90 x 70 x 106MM & fit inside the rubber battery boxes.(3 1/2" x 2 3/4" x 4 1/4" App.)

Right voltage, but 5amp/h will probably struggle to start it - if it had a kickstarter then no problem, but the electric boot needs a higher ampage to crank the piston over. Standard is ( I think ) 12amp/h so you are going to want at least 9-10 amp/h and they aren't going to be that small.  You might find the high tech batteries may be smaller but they are expensive. Could you fit a standardish sized battery in one of those custom battery boxes the Chopper crowd use? Would it fit above the swingarm pivot where the airfilter would usually fit? Chrome/alloy if you want it noticed or matt/satin black if you don't.

With a bit of research i decided to get the "YTZ7S Westco Motorcycle Battery 12V 6Ah (12VZ7S)" for £60.

The anti gravity batteries claim it will start everyday with bikes up to 400cc on 6ah and 130cca. The Westco produces the exact same power output but is a tiny bit bigger (only slightly!) and a lot cheaper! one review said its used everyday for the past two years on his Hornet 600.

Can start making a box now!

Cheers for the help guys!
