Battery and Charger, Frequently Asked Questions How does the charger work? When the battery level is low, the charger works transmits more current more rapidly to the battery to quickly increase the electric charge. When the battery near its full charge, the charger gradually reduces the transmission of current. When the battery is fully charged, the current transmitted by the charger is close to 0 amps. The charger should maintain the full electric charge within the battery, without excessively charging the battery. For complete charging instructions, please refer to the instruction manual provided with the battery charger.
19

4. Battery and Charger
Can I use other chargers?
We have provided you with the charger that accurately matches your battery type, capacity and chemical nature. In order to ensure the safest and the most effective charging of the battery, we suggest that you use only the original charger we provided. DO NOT use any other chargers or charging methods to recharge the battery.
If the battery of the travel scooter cannot be charged. * Please ensure that the fuse on the battery pack is working. (Picture 7). – Please make sure the charger wire is correctly inserted into the battery charge port and that the charger is correctly inserted into a functioning wall socket.
How often is the battery charged for once?
To judge how often the battery of the travel scooter should be charged, two main factors need to be considered: How often is it used? If used daily, charge the unit immediately after each use to maintain proper battery life. We recommend that you charge the battery between 8-12 hours after each daily use. If you charge the battery overnight, you should have a fully charged battery each morning. If you use the scooter once per week or less frequently, you can charge the battery once per week for at least 12 hours. If not in regular use, please make sure the battery is near full and not stored with the battery on empty.
Please keep the battery fully charged and avoid in-depth dicharge of the battery. As to the charging instructions, please refer to the instructions of battery charger provided along with the battery charger. If you are using the scooter less frequently, continue to charge the battery bi-monthly for at least 12 hours each time to maintain the battery life and performance.
20

4. Battery and Charger
How to maximize the battery life?
Deep cycle battery charging can prolong the battery life and increase the battery performance. To ensure battery life and performance, keep the battery fully charged as much as possible and keep the battery away from extremely hot or cold environments. If the battery is left in a discharged state or left in extreme temperatures, it might be permanently damaged and become unreliable.
Please turn off the travel scooter and remove the key when you are not using it in order to extend the battery life.
How to achieve the maximum mileage or distance of a single charge?
Maximum mileage is generally achieved under ideal conditions such as riding on smooth, flat or hard surfaces. Riding on hills, cracked pavement, uneven surfaces, dirt, sand, and winding roads, will influence the maximum driving mileage of the scooter. – Please fully charge the battery each day if you use the travel scooter daily. – Control the luggage weight and only carry essential items. – Try to maintain a constant speed in the operational process of the travel scooter. – Avoid the conditions of moving and stopping the scooter suddenly. – If the scooter is used only once in a month or less, it is suggested that the battery be charged continuously twice per month for at least 12 hours in order to maintain the battery performance. – Make sure that all wire harness has been fixed properly.
21

4. Battery and Charger
Which type and capacity of the battery should I use?
Your travel scooter needs two cycling batteries. We suggest you use the sealed maintenance-free battery, such as AGM battery or gel battery. Please do not wet the battery or remove the protective cover. The capacities of the batteries of different manufacturers are different, please refer to the product specifications table.
Batteries contain corrosive chemicals. Please use AGM battery or gel battery in order to reduce the risk of battery leak age and explosion. Sealed battery cannot be repaired by users. Please do not remove the protective cover of the battery.
Why does the new battery seem to be in poor performance?
– The chemical technology adopted by deep cycle batteries is different to that of automotive batteries, nickel-cadmium batteries, or other ordinary batteries. Deep cycle batteries need to let out an electric charge, then recharged immediately afterwards (8 to 14 hours). – We are in close coordination with the battery manufacturers and strive to provide the most suitable battery that meet the power demands of certain travel scooter. Your new battery is fully charged before delivery to customer. New batteries may encounter extreme temperatures in transit, which will affect its initial performance. High temperatures can reduce the electric charge of the battery. Low temperature can reduce the available power of the battery and extend charging time at the same time. It may take a couple of days for the battery temperature in a travel scooter to be stabilized and adapt to its new temperature or ambient temperature. More importantly, it needs several charging periods (partially discharged after being fully charged) to establish the vital chemical equilibrium, which is essential to maintain the best performance and longest life of the battery.

Your authorized supplier should periodically check the motor brushes for wear. Console, charger and rear electronic device: These parts must be protected from moisture. If these parts accidentally encounter wet objects, please be sure to wait until they are completely dry before using the travel scooter again. Replacement of the nylon lock nuts: The nylon inserted lock nuts removed during regular maintenance, installation or disassembly of the travel scooter must be replaced with the new one. The nylon inserted lock nuts are not reusable as they are likely to damage the nylon insertion, resulting in reduced safety. The new nylon inserted lock nuts for replacement are available at local hardware stores or by the authorized supplier. Storing the scooter: If you do not use the travel scooter for a long time, we suggest you; Fully charge the battery before storing the travel scooter and remove the battery pack on the travel scooter. Store your travel scooter in a warm and dry place. Do not store your travel scooter in places where there may be extreme temperatures. The recommended storage temperatures are between -10°C~ 70°C. Batteries may suffer permanent damage, unreliable performance and shortened service life if they are frequently deeply discharged, infrequently charged, and stored at extreme temperatures or in a non-fully charged state. If your travel scooter is stored for a long period of time, we recommend that you charge its battery regularly to ensure good performance.
The battery temperature must be higher than the freezing point temperature, and it is not allowed to charge the frozen battery. Charging a frozen battery may cause damage. When your travel scooter will be stored for a long time, you can put several boards under the frame to avoid direct contact with the ground. This way, the bearing capacity of the tire can be reduced, and the possibility of forming marks in the tire area that contacts the ground can be reduced. Product treatment: Please be sure to dispose of your travel scooter in accordance with relevant local and national laws and regulations. For information on proper disposal of packaging, metal frame parts, plastic parts, electronic devices, batteries, neoprene, silicone and polyurethane materials, please consult your local waste disposal facility or the authorized supplier.

Here are a Few Ways to Keep Your Batteries Healthy. – Keep your batteries at room temperature. Heat is by far the largest factor when it comes to reducing battery life. – Batteries deteriorate over time, whether they’re being used or not. – We suggest that after 30 partial charges, you allow for a complete discharge of the battery before recharging. This will allow for a recalibration of the power gauge. – Gradual deterioration in performance will result if the battery has been left in a discharged state.
