Questions about this item

How long will the 42 Wh capacity last before the battery needs recharging during continuous use?

The 42 Wh lithium-ion cell at 7.72 V delivers roughly 5.4 Ah, so run-time depends on the Duet 5’s power draw rather than a fixed hour count.

Does the battery generate noticeable heat or fan noise when the Chromebook runs all day?

As a passive lithium-ion pack it produces no fan noise; warmth under heavy load is normal but stays within the cell’s rated thermal limits.

Which part numbers must my Duet 5 already use for this replacement to fit?

It replaces Lenovo part numbers L21C4PG0, L21D4PG0, L21L4PG0, L21M4PG0, SB11D64647, SB11D64648, 5B11D64649, 5B11D64650 and 2ICP4/46/111-2.
