Four-pack Li-ion cells for PSP models

This four-pack supplies 1200 mAh lithium-ion cells rated at 3.7 V and 4.4 Wh each. They replace the Sony PSP-S110 battery and fit PSP 2000 through 3010 series handhelds. The pack targets owners who want several ready spares for long trips or multi-device households.

Steady output with built-in protection circuits

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards that meet UL 1642 and CE requirements. The protection keeps voltage stable during extended play sessions instead of sagging after a short burst. Consistent delivery helps the console maintain brightness and wireless performance until the cell is truly depleted.

Direct drop-in replacement with no tools required

Installation is a simple battery-door swap on every compatible PSP model; no screws or adapters are involved. The only common issue is inserting a cell upside-down, which prevents the door from latching. Users who ignore the polarity markings may also trigger the protection circuit, requiring a brief charge cycle to reset.

Questions about this item

Does the 3.7 V 1200 mAh cell run hot during long PSP sessions?

Each 4.4 Wh lithium-ion pack includes over-heating protection circuitry, so temperature stays controlled even during extended play on a PSP-2000 or PSP-3000.

What charger do I need for these four PSP-110S packs?

They charge inside any compatible Sony PSP-2000, PSP-2001, PSP-3000 or PSP-3001 unit — no separate charger is required.

Will the BA-4B-PSP110S-D fit the older PSP-2005 I still use?

Yes, the replacement is listed for every PSP-2000 series model including the PSP-2005 and all PSP-3000 series handhelds.
