Battery operation and charging

• The Carl chair is battery-powered and starts as soon as the “Up/Down button” or “Brake button” is activated. Under normal working conditions, a fully charged battery lasts up to 3 months. When the battery level is below 20%, it is indicated during operation with a beep sound. The Carl chair has an associated battery charger that handles 100- 240V mains voltage. The charging socket is located on the back of the chair and the status is indicated on the battery charger (see below). Regular charging of the battery is recommended as full discharge reduces the life of the battery. Recharge the battery every month, but at least every three months to avoid damage to the battery that otherwise occurs through self-discharge.
• A new or fully discharged battery must be charged for 24 hours. When the battery is fully charged, the charge automatically switches to maintenance charging to avoid overcharging.

• The indicator on the battery charger shows the following

• Batteries have a limited life span, and the battery module must be replaced under normal working conditions after about four years. Year of manufacture and month can be found on the battery’s nameplate. If the operating time is greatly reduced despite 24 hours of charging, the battery module must be replaced. At low battery level it is possible to use the chair with the charger connected but it is not recommended. A new battery module is ordered from Rini and is easy to replace.
  Only the dedicated charger for Carl chair must be used.
