Frequently Asked Questions

Which radios are compatible with the RPB-BL1719?

The battery is designed for Hytera TC-508, TC-518, TC-580, and TC-446S models that use the BL1719-format battery. Before purchasing, check the battery model designation on the back of your radio.

How long does the 1650 mAh battery last on a single charge?

Operating time depends on the radio model, transmission power, duty cycle, temperature, and battery condition. For the BL1719, Hytera cites approximately 12 hours with a 5/5/90 duty cycle as an example, but actual results may vary.

Are the 1650 mAh and 1700 mAh BL1719 the same battery?

Both nominal capacities are listed for the BL1719 on Hytera regional sites. Physical and electrical compatibility must be checked by model, voltage, contacts, and the radio’s manual; do not rely solely on the BL1719 name.

Can the battery be charged in cold conditions?

According to the manufacturer, the suitable charging temperature is 0 to +45 °C. If the battery is frozen or very cold, let it safely warm to room temperature before charging.

Is the battery waterproof?

The battery is rated IP54. This does not mean it can be submerged. Protection also depends on proper installation on the radio and the condition of the seals.

When should the radio battery be replaced?

Consider replacement if the runtime has significantly decreased, the battery overheats unusually, does not charge properly, or if the casing is swollen or damaged. Do not continue using a damaged lithium-ion battery.

When is the RPB-BL1719 the right choice?

The RPB-BL1719 is the right choice if your radio uses a BL1719-format 7.4 V battery and your current battery’s runtime has decreased. A second charged battery is useful for hunting and long work shifts where a charger is not available.

If your radio is a TC-446S Enhanced or a newer version with a standard BL1720 battery, always check compatibility before ordering. Do not use a physically similar battery with different voltage or contact layout.

Recommendations

We recommend removing your existing battery before ordering and comparing the model designation, nominal voltage, and contact layout. The radio model name alone may not be sufficient, as different production versions of the same series can use different batteries.

Charge the battery only with a charger compatible with its chemistry, voltage, and model. For longer storage, do not leave the lithium-ion battery fully discharged or in a hot car. Regularly check your spare battery and charge it according to the manufacturer’s maintenance instructions.

If the battery swells, leaks, smells unusual, or heats up excessively during charging, stop using it immediately. Cover exposed contacts and take the battery to a proper battery and accumulator collection point – do not dispose of lithium-ion batteries in mixed household waste.
