In order to get the maximum life from your battery, you should take care to use, store and recharge it correctly. We do not recommend completely discharging the battery on a regular basis; this will reduce the capacity and lifespan of the battery. If the battery becomes fully discharged, recharge as soon as possible. We recommend charging the battery at least once a month.
Over time the capacity of the battery will reduce, eventually, the battery may need replacing. The service life of the battery will vary according to usage. The old battery should be disposed of responsibly, in accordance with local regulations. Please take the old battery to an authorised Brompton Electric dealer, who will be able to assist you in the disposal and obtaining a replacement.
The battery should always be used in conjunction with a compatible Brompton Electric bag, do not attempt to use the Brompton Electric battery without the front luggage.
The battery should be charged indoors in dry conditions and at room temperature. This can be done in several ways, with the battery and bag attached to the bike, in the bag separately from the bike, or the battery on its own. Follow the instructions contained on the label affixed to the battery and battery charger. Once the battery is charged and the charger cable removed (remembering to unplug the charger from the mains electricity supply), ensuring the rubber charging port cover on the battery is properly closed.
Keep the battery and charger out of direct sunlight when charging.
If you intend to store the battery (without use) for an extended period of time, we recommend first charging to 28-47%, this is shown by 2 lights on the indicator. This will reduce the amount the battery discharges over time.
Do not store the battery for long periods when fully charged or fully discharged.
The battery should be stored in a dry location, in a temperature range above 0 °C and below 20 °C, the optimum storage temperature is 10 °C. It is recommended to charge the battery to full at the beginning of using the battery after a long period of storage and to then drain it completely.
CLEANING & CARE
Remove the battery before cleaning & maintaining the bike. Do not use a jetwash or hose to clean the bike or the battery. This can force water into the motor, battery and electrical components; damaging them and causing them to malfunction. Do not use solvents, aerosol cleaners or degreasers to clean the bike. For best results clean the bike with warm soapy water and a sponge. Keep the battery dry, wipe the battery down with a dry cloth to clean it.
Do not submerge the bike, hub motor or battery in water; this can allow water to enter the motor, battery and electrical systems. This could cause the battery to overheat, burst or ignition. Do not place the battery or bag down on a wet floor, this could allow water onto the battery connector.
Exposure to humid conditions, marine environments or salinity of any kind can cause corrosion of the bicycle components, frame parts, and fasteners. This can cause cosmetic damage as well as shorten the lifespan of the parts. Clean the product regularly and store in a dry environment to avoid corrosion of the parts.
During cold weather, we recommend charging and storing the battery indoors at room temperature before attaching the battery to the bike for riding. Do not charge the battery at temperatures below 0 °C or above 45 °C with the ideal temperature being 10 °C. After the bike has been used in cold weather, ensure the battery has been indoors for at least an hour before charging; this will allow it to reach room temperature. Do not charge when the battery is cold. The battery should always be used in conjunction with a compatible Brompton Electric bag, do not attempt to use the Brompton Electric without the front luggage. The bicycle is designed to work at temperatures between 0-40 °C, outside of this temperature range the product may malfunction.
