Shipping, returns, warranty, safety, fitment, and wholesale support for CBJJ lithium batteries. Share the right details once, and our team can confirm the next step with less back-and-forth.
Use this form for custom packs, private label, dealer pricing, repair-shop replenishment, fleet projects, marine starting, and Amazon inventory planning. Add the technical and commercial details needed for a quote-ready review.
These store policies are written for a US-first independent store and should be reviewed with your payment processor, warehouse, and legal advisor before launch.
US orders ship from CA/NJ warehouse inventory when stock is available. Large LiFePO4 packs require compliant ground freight.
Unused products can be returned within 30 days. Installed, modified, damaged, or incorrectly wired batteries need support review first.
CBJJ warranty covers manufacturing defects, BMS faults, and abnormal capacity loss under proper use.
Battery after-sale support needs a cleaner intake than a normal contact form. This flow captures order, product, voltage, charger, photos/video link, and safety notes so CBJJ can route a claim to support, warehouse, or engineering review.
Safety content should be visible before purchase because battery buyers need confidence and clear operating boundaries.
Confirm voltage, connector, polarity, physical size, discharge current, charger voltage, and BMS current rating before connecting any battery.
Use the correct lithium charger. Do not charge below 0C unless the pack has low-temperature charging protection. Never leave a damaged pack charging unattended.
Store batteries in a cool, dry location. For long-term storage, charge to 40-60% and inspect voltage every 60 days.
Answers for the most common pre-sale and after-sale questions.
Match nominal voltage, full charge voltage, connector, polarity, pack size, BMS current, and chemistry. If you are unsure, send a photo of the old label and connector through the inquiry form.
Small cells and compact packs can ship with proper compliance documents. Large LiFePO4 packs usually ship by ground or freight because of lithium transport rules.
Yes. Send quantity, target market, battery model, required certification, packaging needs, and expected delivery date. The sales team can quote tiered pricing.
CBJJ is prepared for major card and wallet payment methods through a secure checkout provider. Final availability depends on market, order value, shipping route, and payment review.
Order number, device model, photos of the pack and connector, measured voltage, charger model, fault description, and whether the battery has been opened or modified.
These policy sections explain how customers can review store terms, privacy practices, and cookie choices before checkout.
Orders, pricing, taxes, availability, delivery estimates, warranty eligibility, and return approval are subject to final confirmation by CBJJ and its payment, warehouse, and compliance partners.
Customer information is used to process orders, respond to inquiries, provide warranty support, maintain account preferences, improve site experience, and meet legal or logistics requirements.
Essential storefront storage keeps cart, market selection, wishlist, and support messages working. Optional analytics and marketing storage are controlled by the site privacy preferences.
