The pack uses a proprietary connector layout, so confirming the exact model avoids fitment issues. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS for safety and environmental compliance.

Steady output with integrated safety circuits

In normal use the battery maintains a stable 4.8 V supply while the protection circuitry limits current spikes and prevents thermal runaway.

Questions about this item

Does the Estry LL300 battery come with a charger or any cables in the box?

The listing covers the battery pack only; no charger or cables are mentioned, so they must be sourced separately if your device does not already include them.

My device is an LL300N — is this the correct replacement or should I look for a different capacity?

The LL300N appears in the compatible model list, and the 4.8 V 5000 mAh rating matches the original specification for that model.

What does the 24.0 Wh rating mean for actual run-time in my HV301 handset?

The 24.0 Wh figure is the total energy capacity; real-world run-time depends on the handset's power draw, so divide 24.0 Wh by the device's average wattage to estimate hours.
