2-Power pääakku korvaa TPN-I124 - akku

When your HP Pavilion or Envy laptop starts losing charge faster than it should, this 2-POWER replacement battery restores dependable runtime without the expense of a new machine. It is built around a 3-cell lithium-ion core that delivers 11.55 V and 3470 mAh (41.7 Wh), matching or exceeding the original TPN-I124 specification. Unlike generic aftermarket cells, this pack includes four independent protection circuits — overcharge, over-discharge, overcurrent, and short circuit — so the battery stays safe through hundreds of charge cycles. The black casing fits internally, exactly where the original sat, and the connector aligns with HP’s HT03XL, HSTNN-DB8R, L11421-2C1, L11421-421, and L11119-855 part numbers.

In daily use

Installation is internal and straightforward: power down the laptop, remove the bottom cover, unplug the old battery, and connect this one. After a full charge, the battery calibrates normally and provides steady output for everyday tasks — browsing, documents, video calls, and light media. The protection circuitry keeps the cells within safe voltage and current limits, which helps maintain capacity over time. Expect a service life of at least 500 charge/discharge cycles under typical use.
