  • MiKroh 2 Lightweight Racing Battery


The MiKroh (1 Ah) Racing Battery is intended for use in any automotive OR motorcycle engine up to 2.5 L displacement. While the MiKroh can start much larger engines it is not recommended because you will have a shortened cranking time. As an example, a fully charged MiKroh starting a 2.5 liter inline 6 cylinder engine with 9.5:1 compression gives about 10 seconds of crank time. Even on a hard to start carbureted vehicle this is generally considered adequate. If this was done on a larger V8 7 liter motor you may only have only 2 to 3 seconds of starting time, and may easily fully discharge your battery.

The MiKroh2 (2 Ah) Racing Battery is intended for use in ANY automotive OR Motorcycle engine. Again every application is different and some care will always have to be taken by the driver to not fully discharge the battery. If the engine is starting to crank slower than normal or there is a prolonged cranking session with a hard to start engine, then stop and recharge the Mikroh, or connect a “booster” unit to help trouble shoot the problem with starting the engine.

How do I install my Kronospark Racing Battery?
Please refer to the MiKroh and MiKroh 2 Installation Guides.  Installation guide for the Likroh Racing Battery coming soon.

How long will my Kronospark Racing Battery last?
Your racing battery will generally give you up to 300 starts and last about 1 to 3 racing seasons depending on your track usage.

How do I measure the parasitic load of my vehicle?
Using a multimeter that has a milliamp current range. Connect one lead of it to the positive terminal of the battery, connect the second lead of it to the positive cable feeding power to the vehicle. Make sure the vehicle ignition is in the off position and there are no accessories on such as lights etc. Make sure the doors are closed and the vehicle is in its “resting” state. Generally parasitic loads will be in the 5-10 mA range. If your vehicle has more than 40mA of parasitic load special considerations would have to be given to the battery capacity used in such applications. Especially if the vehicle will sit for periods longer than 24 hours without charging. Many vehicles will have a higher current draw when they are first connected, but will drop down to a “resting current” in 10 seconds to 5 minutes.

Do I need to charge my Kronospark Racing Battery?
Your racing battery will conveniently come with a Kronospark approved trickle charger and charger port that will keep your racing battery charged when it’s not in use.  If you are not going to use your vehicle after a 24 hour time period, be sure to reconnect it to the charger to keep it fresh.  A full recharge should take an hour and  a half.

How do I recycle my Kronospark Racing Battery?
Recycling is important.  You have two easy options to recycle your Kronospark battery:

  • Call 1-800-CLEANUP or check for listings under “car battery” recycling locations. It takes less than 2 minutes but makes all the difference in helping mother earth.
  • OR

  • Contact Kronospark at (608) 628-8941 or to receive a free return shipping label.  Then send the battery back to Kronospark and we’ll take care of the rest.

Will my Kronospark Racing Battery last me through a day of starting and stopping?
Yes.  As long as your engine and alternator have at least 5 minutes to charge your battery between starting and stopping your Kronospark Racing Battery will definitely keep cranking those powerful amps for your race.

What do I do if my battery fully discharges?
Unfortunately, if you fully discharge your MiKroh battery it is no longer covered under the Kronospark 1-year warranty. Be sure to practice good battery care by removing connecting it to the included trickle charger within 24 hours of last use.  In the case that your battery does fully discharge you may try jump starting your vehicle or recharging it.  We cannot guarantee that this method will work, but if it does, be aware that the cranking amp capacity will most likely be significantly lowered. If the resting battery voltage falls below 12.0 volts you are in danger of having a permanently harmed battery. Ideally the voltage will be above 12.4 volts when resting to prevent premature sulfation and loss of capacity.
