Direct replacement for ThinkBook 14 and 15 G4 G5

This GreenTech battery replaces OEM part numbers including 5B10Z21197 and L19D3PDA. It fits Lenovo ThinkBook 14 G4, 14 G5, 15 G4 and 15 G5 models across multiple sub-variants. The 3 cell lithium-ion pack restores mobile power without modification.

Drop-in fit frees the original charger for spare use

The pack matches the original 11.52V voltage and 45WHR capacity so the laptop charges and reports capacity normally. No BIOS update or adapter change is required. The slim 7.5 x 3.25 x .3 inch form seats in the existing bay and leaves all ports accessible.

Low self-discharge chemistry keeps heat

CE, FCC and RoHS certified cells deliver stable current with minimal thermal output during typical office workloads. The battery maintains charge well during storage and produces no audible noise. It is not suited for users needing higher capacity than 45WHR or a different voltage platform.

Questions about this item

How long does the 45WHR capacity last under sustained load?

The 45WHR, 3904mAh lithium-ion pack is rated for typical all-day office workloads on compatible ThinkBook 14 and 15 models; actual runtime varies with screen brightness, CPU load and connected peripherals.

Does the 11.52V 3-cell design run hot or make noise during continuous use?

The battery has no moving parts and produces no audible noise; normal warmth may occur during heavy charging or discharging, but the built-in circuit protection keeps temperatures within safe limits.

Which ThinkBook chassis must I already own for this L19D3PDA pack to fit?

It fits Lenovo ThinkBook 14 G2 through G5 and ThinkBook 15 G2 through G5 variants including ARE, ITL, ACL, IAP, ABP and IRL sub-models listed in the compatibility table.
