The S3M30KX/NIB and S3M40KX/NIB UPS models include a robust internal battery system. The S3M60KX and S3M80KX models
require external battery packs. External battery packs may be used with the S3M30KX and S3M40KX models to extend runtime.
Adding external batteries will increase runtime and require additional recharge time.*

Do not connect or disconnect battery packs when the UPS is running on battery power.
