Frequently asked questions
How do I size battery maintainers?
Add the running loads you intend to power and account for startup surge where applicable. Leave reasonable headroom rather than operating continuously at the limit.
Are watts and watt-hours the same thing?
No. Watts describe power at a moment; watt-hours describe stored or consumed energy over time.
Can I power sensitive electronics?
Check output waveform, voltage regulation and the equipment requirements. Pure sine wave output is commonly preferred for sensitive loads.
What electrical safety features matter?
Overload, over-temperature, ground-fault and circuit protection can matter depending on the product and application; follow code and manufacturer guidance.
Can portable generators be used indoors?
Combustion generators produce carbon monoxide and must never be operated in enclosed or unsafe locations. Follow the generator manufacturer's placement requirements.
How should batteries be maintained?
Use the charger chemistry/mode specified for the battery, maintain ventilation where required and follow battery and charger instructions.
What should I verify before connecting workshop equipment?
Confirm voltage, frequency, continuous/surge capacity, grounding/bonding requirements, connector type and the equipment manufacturer's requirements.
