Changing the output voltage from that reflected in the customer specific CSIR code will result in inaccuracies exceeding those specified above. Note 2: The SMB239 device is not intended to function as a battery pack protector. Battery packs used in conjunction with this device need to provide adequate internal protection and to comply with the corresponding battery pack specifications. |
