AI-Powered supplier vetting

SummaryDanl New Energy Co., Limited is identified as a China-based limited trading company headquartered in Guangzhou, with stated manufacturing operations in Nansha. Its business focuses on smart battery chargers for lithium, lead-acid, and various electric-mobility applications. The supplier reports four production lines, 6–10 quality-control staff, a 97.24 m² manufacturing plant, and substantial export activity. It claims customization, ODM/OEM, two-year full warranty, and free replacement services. However, no certification information or specific customer cases is provided. The materials also contain differing establishment/export-history references, so corporate history should be verified before relying on those claims.

Supplier typeThe supplier is legally described as a limited company and classified as a trading company, while its materials also identify a factory/manufacturer operation at a Guangzhou address. Its business covers battery chargers and related electrical/electronics products, indicating a trading entity with stated manufacturing capability.

After-Sales capabilityDanl explicitly states that it provides after-service and claims a two-year full warranty policy with free replacement. These are clear stated service commitments, although no service process, response-time data, or verification evidence is provided.

R&D capabilityThe supplier states that it designs and manufactures switching-mode technology battery chargers and develops smart chargers for multiple battery chemistries and electric-mobility applications. This supports product-development capability, but no patents, R&D team information, or independently validated technology evidence is provided.

Production capacityThe supplier reports a 97.24 m² manufacturing plant, four production lines, and 6–10 quality-control staff. Its listed product range covers multiple voltage levels, battery chemistries, and vehicle types, providing explicit evidence of production scope, though actual capacity and output verification are limited.

Customization capabilityDanl explicitly states that it specializes in customizing smart battery chargers and provides ODM/OEM services and charging solutions for battery and EV factories or wholesalers. This directly supports customization capability across multiple battery and mobility applications.

Product Q&A

Q:What charger should I choose?

It depends on the type of battery, the capacity of the battery, the application and how much you are prepared to spend. Just tell us your battery information, DANL battery charger engineer will recommend the most suitable charger for you or customized by your batteries and applications.

Q:Can you really connect and then forget about the charger?

That depends on your batteries state and charger's type. Danl lead-acid battery chargers have maintenance mode(floating mode), charger charges with very small current at this mode, so you can forget about the charger but not exceed 24 hours. If your battery is lithium type and without BMS system, please don't forget the charger.

Q:What is the charging time for lithium batteries?

For lithium battery, charging time is often 3-4 hours.

Q:Can I use a lead acid charger for a lithium battery?

No, a lead acid battery charger does not suit for a lithium battery (Li-ion, LiFePO4, LiMnO2 etc.) and a lithium battery charger does not suit for a lead acid battery (AGM, GEL etc.).

Q:What are the dimensions and weight of the charger?

Dimension: 380*150*90mm. Net weight: 7 Kg. Gross weight: 6.5kg.
