Lithium battery, remove some weight, … add something?

Batteries do not last forever and can be easily damaged with a sharp impact or by being mishandled. Sometimes a battery will be pushed until it will no longer take a charge, or the bike just will not start. Having a bike that will not start or turns over slowly has to be the single most scary and annoying thing .oO(Whats wrong now?, How am I going to get home?). The street bikes I have had did not have kick starters, and they were not easily push started.  If your racing, it is never a good thing to DNF (did not finish), because of something as simple as a battery. Lithium battery technology just keeps improving, and with those improvements we all get to enjoy the benefits.  A lithium battery is impact resistant, moisture resistant, lighter weight, has more staring power in a smaller package, has better reliability, a longer service life, and is all around a more robust battery, why wouldn’t I opt for a new lithium battery?

Everything in your life is a reflection of a choice you have made. If you want a different result, make a different choice.



So how much less do the lithium batteries weigh?  Most sport bikes have a battery that is lead acid, is over 11 lbs, and measures 6 (L) x 3 (W) x 5.25 (H). The Ballistic unit weighs 1.7 lbs and measures 4.5″ (L) x 2.5″ (W) x 4.25″ (H) (8 cell unit), and I am sure the Antigravity weights and dimensions are similar .  That is nearly 9 lbs of savings.  I would like to see someone get the same weight savings from carbon fiber, titanium, or aluminum parts for the same price.

I received my battery in a box with foam molded around it.  I would highly recommend using this foam packaging to fill the extra space left by the old battery. The foam helps hold the battery in place and does not put any additional “squeeze” on the battery.


Clean terminals and do not tighten the terminals with no more than 5lbs of torque.  It may not seem like its tight enough, but it is.

Ballistic offers their batteries in a few sizes, 4, 8, 12, and 16 cell designs.


  • Dimensions: 4.5″ (L) x 2.5″ (W) x 4.25″ (H)
  • Weight: 768 grams (1.7 lb).
  • Voltage (Charged): 13.6V.
  • Amperage: 15 Pb-eq A/H.
  • Cold Cranking Amps: 275 CCA.
  • Operating Environment: -18°C (0°F) to 60°C (140°F).

I might preach about ballistic, but that is the brand that I am familiar with.  Doing my homework on Antigravity batteries has proven to be an eye opener.  Antigravity might be a bit more pricey, but the 3 year warranty and build quality is impressive and I might just switch because of that.

Antigravity also offers their batteries in a few sizes similar to the Ballistic sizes, 4, 8, 12, and 16 cell designs. The 4 cell design is shaped a bit differently than the ballistic.  The 4 cell battery has a nice flat profile compared to the ballistic square shape.  Both shapes have their place.


  • 240 CA- Cranking Amps at 32°
  • 9 Ah- Amp Hours
  • Size: 5 7/8″ long x 3 7/16″ deep x 3 3/4″ high
  • Weight: 1lb 9oz

Some Battery Precautions

  • Allowing a battery to drain below 10.5 volts will ruin ANY battery, may it be lithium, lead acid, or ion drive.
  • Do no tighten the cable bolts tighter than 5 ft lbs
  • Do not overcharge a battery with more than 14.4 volts
  • On older bikes that the battery is being replaced, it is important to make sure the charging system is in proper working condition and not putting out more than 14.4 volts.
  • Do not crank an engine for more than 7 seconds in repeated intervals, once or twice is fine, but anymore and this will overheat the battery and ruin it.
  • How the battery is treated and its use makes a big difference when it comes to the lifespan.  Racing will significantly lower the lifespan of any battery.

When or if you changed your battery, what battery did you choose, and why?


Riding motorcycles and wrenching since my preteen years, I have moved from motocross to street bikes. Being a teen back in those days it was tough to get me off of the bike. Now days even though I am very busy being a dad I still have my weekends and go to the track to race and on occasion will do a track day or two.
