Answers to frequently asked questions

Does this battery fit every green laser level?

No, suitability depends on the voltage (3.7 V) and supported connections of a specific leveler, so we recommend that you check the specifications of your tool and compatibility with Huepar models before purchasing.

What does a capacity of 2.6 Ah mean in practical use?

The 2.6 Ah capacity means that the battery will allow the leveler to operate for several hours at average consumption, which is enough for normal short-term work, but not for continuous long-term professional use.

Can the battery be used in other devices?

Use is only possible if the device complies with the correct voltage, connection and manufacturer's recommended specifications. We recommend avoiding use with incompatible devices for safety reasons.

Store the battery in a dry and cool place, charge it regularly according to the manufacturer's instructions and prevent complete discharge, as this will extend its lifespan and operational reliability.

What to do if the battery suddenly loses capacity?

If you notice rapid discharge or reduced capacity, first check the contact conditions, try a different charger and read the manufacturer's instructions; in the event of a persistent problem, seek clarification from an official Huepar service center.
