Motorcycle Battery Eliminator / Charging Capacitor
Strip it back. Lose the battery. Keep the spark.
This battery eliminator (charging capacitor) allows compatible motorcycles to run without a battery, using the generator alone. It’s a popular upgrade for track, MX and enduro bikes, where simplicity, reliability and weight saving matter more than creature comforts.
Built around a rugged, long-life capacitor, this unit is designed to handle the high ripple currents and voltage surges found in real-world motorcycle charging systems – not just look good on a spec sheet. With more usable capacity than many similar-sized units, it helps make points and simple ignition systems more reliable, especially during kick-starting.
Supplied complete with mounting clip, cable tie and connectors for a clean, no-nonsense install.
What it does (and what it doesn’t)
✔ Allows battery-less operation on suitable generator/ignition systems
✔ Saves weight – even compared to lithium batteries
✔ Zero maintenance and no self-discharge
✔ Can be left unused for long periods with no damage
✔ Ideal for track, MX and enduro bikes, with or without power valves
Important limitations (read this bit):
Electric starters will NOT work, no battery = no stored power
Not suitable for ABS or fuel-injected motorcycles
Lights will pulse at idle and improve with engine speed
Not recommended for road bikes, if the engine stalls at night you are left without lights.
This unit does not generate power. All power comes directly from the motorcycle’s generator, so at idle you’ll see natural voltage pulses, this is the engine slowing down on compression and speeding up as it fires. As revs rise you stop noticing this effect, lighting and power valves behave normally – exactly as expected with any battery eliminator.
