Who Should Buy This Battery?
This battery is essential for IdeaPad 730S-13IWL and Yoga S730 users in Nairobi who are experiencing swelling of the internal casing, "No Battery Detected" errors, or a significant drop in mobility.

Lenovo IdeaPad 730S 42Wh Battery Frequently Asked Questions (FAQs)
Can I use a standard 45W charger with this new battery?
While a 45W USB-C charger will work, the 65W USB-C PD charger is required to utilize the Rapid Charge feature supported by this KSh 11,398 battery.
Why is this battery 15.36V instead of the usual 11.1V?
Premium ultrabooks like the 730S use higher voltage architectures to push more power through thinner wires and smaller cells, allowing the laptop to remain incredibly thin while still supporting Thunderbolt 3.
Is it safe to replace the battery myself?
Yes, but the 730S is tightly packed. You must remove the back cover with a Torx T5 driver and be extremely careful when disconnecting the battery ribbon cable to avoid damaging the pins on the motherboard.
