Q1: How should batteries be stored if they are not used for an extended period?

A1: When batteries need to be stored for an extended period, it is recommended to charge them to 50%-60% and then store them in a dry, cool environment, no higher than 25°C. Every two to three months, charge the battery to full capacity and then discharge it to approximately 50%-60% to maintain battery cell activity. Before reusing a battery that has been stored for a long time, it is best to perform a complete charge-discharge cycle to restore it to optimal working condition.

Q2: A hospital has purchased multiple KTI 302054 batteries. How can I easily identify the battery's usage frequency and health status to prevent long-idle batteries from being mistakenly used in high-frequency applications?

A2: This can be done using the "Battery Information Query" function on the VOLUSON E/I device. After installing the battery, go to "System Settings - Battery Management" to view the battery's "Accumulated Charge and Discharge Times" and "Current Actual Capacity" (as a percentage of the initial capacity). Batteries marked "Charge and discharge times <100, actual capacity ≥90%" are recommended as "spare packs." Batteries marked "Charge and discharge times 100-300, actual capacity 80%-90%" are preferred. Idle batteries should be activated (complete one charge and discharge cycle) every three months to prevent capacity degradation.

Q3: When using a KTI 302054 battery in a Voluson E/I device, the "Battery communication interrupted" message occasionally appears, but it recovers after re-insertion. Is this a malfunction?

A3: This isn't necessarily a battery problem; it could be a temporary malfunction in the interface or the device's communication module. First, check the metal contacts between the battery interface and the device's battery compartment for oxidation or stains. If the problem persists after cleaning, install the battery in a functioning device of the same model and test again.
