Lithium Battery Care and Maintenance

Top 3 Battery Care Requirements

  1. Charge battery before first use. The battery may arrive with some charge, regardless of this the battery must be charged for 3 hours on the initial charge and 3 hours for each subsequent charge.
  2. Charge battery immediately when it is depleted. Do not store a depleted battery. This will permanently impact the life of the battery. If the battery is going to be stored for a period of time, fully charge the battery before storing.

Valk Synergy 5 - Top 3 Battery Care Requirements - 1

To ensure the battery maintains optimum performance, follow the guidelines outlined below.

  • For best results, charge batteries in temperatures between 10^ and 30^
  • When battery is charged, disconnect the charger from the power supply and remove the battery from the charger.
  • If a battery is stored or otherwise unused for an extended period, and the battery has no charge remaining when you check it, consider it to be damaged. Do not attempt to recharge it or to use it. Replace it with a new battery.
    • Use only with the battery charger specified by the manufacturer.
  • Ensure that the battery charger electrical cord is not subjected to damage or stress. Do not operate the battery charger if it has a damaged electrical cord or plug.
  • Do not use the charger in wet areas or expose it to rain or water.
  • The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again
  • Explosion hazard – protect the battery against heat; for example, direct sunlight and fire. Do not store batteries in vehicles or locations subject to heat.
  • Batteries can explode in the presence of an ignition source, such as a pilot light. To reduce the risk of serious personal injury, never use any cordless product in the presence of open flame. Exploding batteries can propel debris and chemicals.
  • Do not open the battery – danger of short-circuiting and/or explosion.
  • Do not attempt to destroy or disassemble the battery pack or remove any of its components.
  • Do not touch the battery terminals with metal objects and/or body parts as short-circuit and/or personal injury may result.
  • Explosion hazard – do not open and/or short-circuit the battery.
  • Poison hazard – battery leakage (liquid ejection). Under extreme conditions, liquid may be ejected from the battery – avoid contact. If contact accidentally occurs, immediately seek medical attention, and flush with water. If liquid contacts eyes, immediately seek medical attention, flush with clean water for at least 10 minutes. Liquid ejected from the battery may cause irritation or burns.
  • Dispose of non-serviceable batteries in an environmentally responsible manner and according to local regulations.

Failure to adhere to the requirements above may result in the battery becoming inoperative or battery life being reduced. In extreme cases or abuse, battery overheating or fire may result.

Maintenance

Valk Synergy 5 - Maintenance - 1

Do not use alcohol, petrol, kerosene, corrosive solutions and volatile chemical solvents to clean the electric scooter. Otherwise, it will cause serious damage to the scooter's body and can disrupt the internal circuitry. Do not wash the electric scooter with a strong water pressure. Ensure that the scooter has been turned OFF first before performing any maintenance on it. After charging the scooter, insert the plug back to the charging connector, otherwise you may get an electric shock.

Cleaning and Storing the Scooter

If you find any dirt or stains on the electric scooter, use a soft, damp cloth to wipe down the scooter. You can also use toothpaste and a toothbrush to clean the electric scooter from stains and wipe it clean with a damp cloth. If you find scratched plastic parts, use sandpaper or other grinding materials to polish them up.

If you are not using the electric scooter, store it in a cool, dry location; do not leave it on the street for an extended period. Leaving the electric scooter under the sun or in extremely high or low temperatures can cause rapid aging of the outer body and wheels of the electric scooter and reduce its battery life.

Battery Maintenance

  • Never modify the electrical system. Alterations could cause a fire resulting in serious injury and could also damage the electrical system.
  • Charge with the supplied or recommended charger only. Use of the wrong charger could cause a fire or explosion resulting in serious injury.
  • Battery charging must be performed by adults only. Never allow children to charge the battery.
  • Ensure the voltage and frequency of the charger is compatible with mains electrical supply.
    • Use the battery charger in dry locations only.
    • The battery must be charged before first use.

NOTE: A fully-charged battery will run out of stored power after 120 – 180 days in standby mode. Stored power will run out after 20 – 50 days in standby mode if the battery is not fully charged. If you don't charge the battery in time, it may cause damage to the battery due to excessive discharge; this damage is irreversible. Any battery damage caused by failure to charge in a timely manner will result in a failure to charge in the future and can become irreparable. This will also void the warranty coverage.

Non-professionals should not be allowed to open the battery, otherwise it can potentially cause grave accidents via electric shocks or short circuiting.

Adjusting the Brake Disc

If a brake is too tight, us the M5 hex wrench and turn the screws of the brake disc tensioner pulley anticlockwise, then slightly shorten the length of the tail brake cable. Re-tighten the tensioner pulley after adjusting.

If the brake is too loose, loosen the tension pulley, then pull the brake cable to slightly lengthen it. Re-tighten the tension pulley after adjusting.
