2.11.1.External battery assembling (for the MSB900L):

On the MSB900L board, an external battery can be connected to J3. Attach the battery ground to pin 2. If the customer wants to connect an external battery, then some precautions have to be taken:

The battery is prohibited from charging. Do not use a rechargeable battery!

The RTC device defines a voltage level of 3.0-3.6V, so use an external battery within this range (inclusive of the diode which is pre-assembled onboard).
