You can get used  MOSFETs style reg/recs like the FH020AA thru FH008 from Shindengen made for other bikes.

As long as you match the output wires, you shouldn't have any problems splicing it in.

If you're thinking of changing to a lithium ion battery you might want to think about changing your regulator/rectifier to this:

Why??  Our stock charging system works just fine with one of these https://shop.revivalcycles.com/cart.php?suggest=22355051-b8b5-42c7-9c3c-a2ec5...

Hi all

Something I used for years
BMZ LITHIUM POWERBLOC MODEL 5.5 AH
https://www.bmz-group.com/Products/Starter-Batteries/EN_index_1876.html
You have a perfect fit on the exhaust mount in front of the back wheel
Think I gave $190 for it

You should make sure that your R/R isn't producing too much power. Most lithium batteries like to charge between 14.2 to 14.5 volts (check the battery manufacturer) and a lot of Suzuki R/R's allow over 14.6VDC.

If you are over voltage I'd suggest a "smart" LiFePO4 battery that shuts down the current to the battery if it exceeds the maximum allowed voltage. In fact, without a volt meter on your bike it just makes sense to get a smart battery with internal electronics. This way if you R/R fails and produces an over current situation, your bike won't catch on fire.

All of my bike have a lithium battery installed. It's been 2 months since I last rode my bikes that have a carburetor (the FI bike gets ridden when the roads are clear of sand & salt). Today I put those bikes on the Battery Tender trickle charger just to make sure they were topped off.

When I installed the batteries I also installed charging ports/cables to make the winter and spring charging an easy process. I attached the charger to the first bike (Scrambler) and the indicator on the charger recognized that it had attached to lithium battery and that it was in charging mode. I turned around to see where I hid the charging port on the cafe racer and after a brief search I found it where the seat pan and battery box/inner fender come together. I removed the rubber cap and turned around to see the status of the battery of the Scrambler and saw that the battery was fully charged. It took as long to type this paragraph as it did for the battery to charge...because there was almost zero discharge after 60 days.

I hooked up the charger to cafe racer...same result. These lithium batteries just don't discharge very much over a long period of disuse. If you hate charging your battery every spring after winter storage, that will be a thing of the past with a lithium battery.

My Cafe' bike has an EarthX Lithium battery, and it is parked from sometime in November until April.....sorta weather dependent.  It is put away as soon as the put salt on the roads and stays that way until the spring rains wash the salt off the roads.  There is nothing on the bike that draws any power once the key is turned off.....there are no clocks or computers or anything using power.

I have not put a battery tender on the bike since the battery was new in 2013.........and it fires right up every spring!

Dave, have you removed the decomp controller from your bike?
That does draw about 50ma continuously.

Has anybody tried a small $20 walmart battery like Spammy is using???

Actually this is the battery I have been using.  Even smaller, but its been working good.  Grin

I havent had to at all, but I dont mind jump starting my bike down a hill if needed, some people aint gonna take that chance.  But like I said, its been fine for over a year now. I wanted minimal size and weight, but tired of expensive lithium failures. My brothers been using his for 3 years now, still cranking.

I keep it on a tender when sitting.

Yep.....my compression release is manual, and the controller is gone.

I got this coming in around feb 5.  Very interested in how it will work...It would be really nice to have extra room in the batt box to lengthen the cables for easy hook up and removal.  https://www.walmart.com/ip/BATTERY-BTZ7S-FA/720108216

CCA is a rating that defines a battery's ability to start an engine in cold temperatures. The rating refers to the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts per cell.  This rating method is somewhat vintage and not all that applicable to modern engines with electronic ignition or fuel injection computers......as you likely won't get any spark or fuel when the voltage drops below 10 or 11 volts.

The original battery is in the vicinity of 220 Cold Cranking Amps.

The $38.85 battery from Walmart that Slow Lane listed has 150 Cold Cranking Amps.
https://www.walmart.com/ip/BATTERY-BTZ7S-FA/720108216

The $19.89 battery from Walmart only has 80 Cold Cranking Amps.
https://www.walmart.com/ip/SigmasTek-ST5L-BS-Battery-Replacement/684786640

The EXT12A EarthX Lithium Battery I have is rated at a "pulse" rate of 220 amps and a Cold Cranking Rating of 135 Amps.  Lithium batteries cannot be directly compared to Lead Acid batteries as the discharge is different......Lithium batteries supply a very consistent voltage near the maximum under load - while Lead Acid batteries have a constant voltage drop as the battery discharges.  I ride in weather that is always above 50 and my bike is stored in a heated garage - when I push my starter button the bike always starts within one or two revolutions and I never put much of a strain on the battery.

The 220 Cold Cranking Amp battery that Suzuki installed is a "World Battery", and it along with the multi-grade oils, compression release and choke allow the bike to be started in weather that is soooooo cold that I would never be riding a motorcycle in that weather!  We had a member named Raydawg who lived in Washington State and he rode his Savage as his commuter to work and he had to start and ride his bike in really cold weather, and the 220 Cold Cranking Amps was likely necessary for him......especially as the battery ages and begins to lose some of power it had when new.

So with all that being said - if you ride in warm weather and you don't need to start your motorcycle on a cold winter morning, you likely don't need a battery that has 220 Cold Cranking Amps to get the bike fired up.  Battery performance in warm weather is much better than it is when the battery is at 0 degrees, and your bike will start just fine if the battery can provide cranking power while still provide at least 10.5 volts to the ignition module.....which I believe is the voltage necessary for the Savage ignition to create a spark.  As the battery ages and it can no longer provide the needed cranking battery and voltage - it will need to be replaced.  The smaller batteries have less "reserve" capacity and all other things being equal - it may not provide adequate service at long as the higher powered original equipment battery.

Slowlane.....I believe you did a good thing buying the larger battery! Smiley

Dave thank you for your in depth knowledge the time to put it in writing.  I dont go to casinos but I will put 38 bucks out here in NW Fla to see if I can get more room to move around in the batt box and extend the terminals to allow removal/installation a lot easier.  I will keep the board up to date on this new battery.  Thanks, Slowlane

I like when a battery lists both AH and CCA. If you do the math, that 6AH should be able to supply 150 amps for 2.4 minutes. Much more cranking than should ever be necessary.
Do we know how many amps a savage draws when starting?

The battery demand in NW Florida is far less than it would be in areas where folks ride in cold weather.

I looked it up, and a lead acid battery has 60% capacity at 0 degrees Fahrenheit - so at 60 degree temperatures your battery rated at 150 CCA will likely be able to produce 250 Amps.

Those folks that ride in cold weather have three issues that you likely don't have in Florida.  The battery performance is lower in cold temperatures, the oil is thick and the starter has a tougher time turning the engine over - and the cold fuel does not want to atomize......and it is likely the engine will have to turn over a bit more until the spark plug can get the cold fuel/air mix to ignite.
