Questions about this item

What does the 45 Wh capacity mean for daily use on a Lenovo IdeaPad C340-14API?

The 45 Wh rating stores roughly the same energy as the original battery, so typical mixed workloads should deliver comparable runtime before recharge.

Which connector standard does the L18C4PF3/L18C4PF4 use and what does it limit?

It uses the proprietary Lenovo multi-pin connector that matches the C340 and S540 14-inch series; the interface caps voltage at 15.36 V and prevents cross-series swaps.

Will this battery fit inside the chassis of a Flex-14IML without modification?

Yes, the pack is built to the exact dimensions of the L18M4PF3/L18M4PF4 family, so it seats in the internal bay of all listed Flex-14IML models without trimming.
