Questions about this item

Which CMOS battery version fits the Samsung NP730U3E-S03XE700T1A?

This DBTLAP lithium cell is built to match the NP730U3E and the NP730U3E-S03XE700T1A motherboard socket, so the single listed version covers both model numbers.

What does the 3 V lithium cell actually do once installed?

It powers the real-time clock and holds BIOS settings while the main battery is removed or drained, keeping date, time and boot order intact.

What connector standard does this CMOS battery use and what does it limit?

The battery plugs into the standard two-pin motherboard header, limiting use to laptops that accept that exact pin spacing and 3 V lithium chemistry.
