Replacement Battery for Tab Active 3

This KingSener EB-BT575BBE battery replaces the original power cell in Samsung Tab Active 3 8.0 2020 tablets. It matches models SM-T570, SM-T575, SM-T575N and SM-T577. The 4900mAh Li-ion pack delivers 3.85V and is built with high-quality cells and PCB for stable capacity. Field technicians and mobile workers who need a direct swap will find it fits the existing bay without modification.

100% Compatible Fit and Conditioning Tips

The unit ships brand new at 100% of design capacity with no false rating. First use requires two or three full charge and discharge cycles at low current to reach peak runtime. Avoid leaving the charger connected continuously during operation. Store above 80% charge if the tablet is unused for a month, and keep the pack away from heat, humidity, fire and water. No extra cables, tools or software are included.

Li-ion Construction and Daily Handling

Black Li-ion cells are housed in a rigid enclosure that matches the original dimensions exactly. The connector layout aligns with the tablet's internal header so installation is a simple plug-in. The chemistry tolerates regular cycling but degrades if kept at full charge while plugged in for long periods. Physical puncture, crushing or disassembly is unsafe. Users who need hot-swap capability or a secondary pack for rotation should note this is a single internal replacement only.

Questions about this item

How often should I cycle the EB-BT575BBE battery to maintain its 4900mAh capacity?

Fully charge and discharge the battery from low current two or three times when new, then keep it above 80% charge if stored for a month or longer.

What voltage limit stops the EB-BT575BBE from delivering power under sustained load?

The cell chemistry is rated at 3.85V; the protection circuit cuts output when voltage drops below its safe threshold during heavy draw.

Does the EB-BT575BBE get hot or noisy when powering a Tab Active 3 all day?

It is a sealed Li-ion pack with no moving parts, so it runs silently; warmth during continuous use is normal but excessive heat suggests a fault.
