FOCUSTEC 2955C7 58-000280 6300mAh 3.8V laptop battery

SKU CH-3SJE-Y5FEY

Replacement battery for Fire HD 10.1 9th M2V3R5 delivering 6300mAh at 3.8V with 500-cycle lithium-polymer cells

  • Battery TypeLithium-Ion
  • 6300mAh capacity powers the Fire HD 10.1 9th all day
  • 8V 23.94Wh Li-Polymer cell matches original voltage and energy
  • 500 impulse-discharge cycles keep the battery healthy longer
  • ISO9001 RoHS CE UN38.3 MSDS certifications confirm safety compliance
  • Fully compatible with Fire HD 10.1 9th M2V3R5 for drop-in fit

Direct Replacement for Fire HD 10.1 9th M2V3R5

This lithium-ion battery is built as a direct replacement for the Fire HD 10.1 9th generation tablet carrying the M2V3R5 identifier. It restores the original 6300mAh capacity at 3.8V for 23.94Wh of energy. The pack uses a lithium-polymer construction rated for 500 impulse discharge cycles. It suits owners whose factory cell no longer holds a useful charge.

Thermal Behaviour and Power Delivery

The lithium-polymer chemistry runs cool during typical tablet workloads such as video playback, reading or light browsing. No active cooling is required and the cell produces no audible noise. Power delivery follows the original 3.8V specification so the tablet's power management sees no change in behaviour. The 23.94Wh rating matches the OEM energy budget.

Upgrade From a Degraded Original Cell

This unit replaces a worn-out factory battery that has lost runtime or shuts down under load. The jump is worth it when the tablet no longer lasts through a normal day or fails to hold standby charge. It is not for users who need a higher-capacity pack than the original 6300mAh design or who are repairing a different tablet model.

Questions about this item

How do I install the 2955C7 58-000280 battery in my Fire HD 10.1 9th M2V3R5 and which step is most often missed?

Power off the tablet completely, remove the back cover carefully, disconnect the old battery connector, connect the new 3.8V 6300mAh pack, then reassemble; the step most often missed is forgetting to fully power down before opening the case.

What maintenance or replacement will the 2955C7 58-000280 battery need over its life?

The Li-Polymer cell is rated for 500 impulse discharge cycles; after that capacity drops noticeably, so plan a replacement once run-time falls below your needs.

What limit appears first when the 2955C7 58-000280 battery runs under sustained load?

The 23.94Wh capacity and 3.8V nominal voltage set the energy ceiling; continuous high draw will hit that limit before thermal or cycle-life constraints.
