PowerRay Battery PR-S4 for Samsung Galaxy S4, 2600 mAh, Bulk

The PowerRay PR-S4 is a direct replacement battery for the Samsung Galaxy S4, engineered to restore original runtime without the cost of a new phone. Its 2600 mAh lithium-ion cell matches the capacity of the factory battery, so you can keep using your S4 through a full day of calls, apps, and media. Unlike universal batteries that require adapters or compromise fit, this model is shaped precisely for the Galaxy S4’s battery compartment and uses the same connector, making installation a simple swap.

Highlights

• 2600 mAh lithium-ion capacity for all-day use
• 3.8 V nominal voltage, 9.88 Wh energy rating
• Compatible with Samsung Galaxy S4 models GT-I9500, GT-I9505, GT-I9506, GT-I9515
• Built-in protection against overcharge, over-discharge, over-current, and short-circuit
• Rechargeable design rated for 500+ charge cycles
• Bulk packaging for cost-effective replacement

In daily use

Because the PR-S4 uses the same lithium-ion chemistry and voltage as the original Samsung EB-B600BE / EB-B600BU, your Galaxy S4 will report accurate battery percentage and charge normally with the original charger. The protection circuit prevents damage from common charging mistakes, and the cell is designed to maintain stable performance across a wide temperature range from 0°C to 45°C during operation and -20°C to 60°C in storage. This makes it a reliable spare for travel, outdoor use, or as a second battery to swap when you're away from a power outlet.
