Page 17: Storage
5. Storage The storage area of REXC series batteries must be clean, ventilated, dry and without direct sunshine. All lead acid batteries lose capacity when standing on open circuit because of self-discharge. The result is that the voltage of open circuit is decreased, and the capacity also decreased. - Page 18 Narada Power Source Co., Ltd. REXC operation manual V1.2 6.4 Operation and Maintenance Precautions Insufficient Charge If the floating voltage is not set correctly (too low or not compensate according to temperature), the battery system will in an insufficient charge state for a long period of time.
