Frequently Asked Questions

What are the available payment methods?
We accept payments through T/T (Telegraphic Transfer), Western Union, and PayPal. Standard price terms include FOB, CFR, and CIF.
What is the typical lead time for shipping?
Products are generally dispatched within 30-35 days after receipt of bank confirmation. Tracking numbers and product photos are provided via email upon shipment.
How should the battery be stored?
Batteries should be stored in a cool, dry place away from heat sources and direct sunlight. Avoid storage in environments containing acid gas.
What maintenance is required for unused batteries?
To avoid irreversible sulfation, unused batteries should receive a freshening charge every three months. Do not store them in a discharged state.
What safety precautions should I take?
Never short-circuit the terminals, do not charge in sealed containers, and keep away from fire to prevent explosions. Use cotton cloth for cleaning and avoid organic solvents like petrol.
How long do these batteries last in storage?
The ML series batteries can be stored for up to 6 months at 25°C (77°F) before a freshening charge is required. Higher temperatures will shorten this interval.
