The Lenovo IdeaPad 720S Touch-15IKB (81CR0005US) 79Wh Battery is a specialized, ultra-high-capacity internal power unit designed for the 15-inch 4K touchscreen flagship. Unlike standard IdeaPad batteries, this unit provides a massive 79Wh of power to sustain the NVIDIA GTX 1050 Ti graphics and the UHD display. The Lenovo IdeaPad 720S Touch-15IKB 81CR 79Wh Laptop Battery Price in Kenya is KSh 9,958, providing a premium replacement for one of Lenovo's most powerful thin-and-light machines.
This battery carries the model numbers L17M4PB1 or L17C4PB1 and operates at a higher voltage of 15.36V. At KSh 9,958, this is a critical investment for the 81CR0005US model, as the high-resolution 4K touch panel and Quad-Core i7 processor can cause rapid degradation in lower-quality cells. Replacing a failing battery in this model is essential to prevent internal heat buildup that can damage the slim aluminum chassis.
Who Should Buy This Battery?
This battery is essential for 720S Touch-15IKB (81CR) users in Nairobi who use their laptops for high-end creative work, video editing, or multitasking. At KSh 9,958, it is the correct choice for those whose laptops are "throttling" (slowing down) because the current battery can no longer provide peak power. It is also a vital fix for users noticing the 720S chassis becoming uneven, which often indicates the internal lithium cells are beginning to expand.

Lenovo IdeaPad 720S Touch-15IKB 81CR Laptop Battery Design and Build Quality
The Lenovo IdeaPad 720S Touch-15IKB 81CR 79Wh Battery features an elongated 4-cell architecture designed to span the width of the internal chassis. For KSh 9,958, the battery utilizes a high-density 15.36V configuration, which is necessary to drive the dedicated GTX graphics and the Thunderbolt 3 controller. The casing is ultra-slim but rigid, designed to act as a structural heat sink that dissipates warmth away from the motherboard during heavy usage.
The battery uses a specialized high-bandwidth connector to handle the increased current flow required by the 90W power system of the 15IKB series. It is manufactured with flame-retardant ABS materials and features reinforced screw mounts to ensure a vibration-free fit within the premium aluminum body.
