Lithium battery documentation is the single most common cause of a held Zen 4 shipment.
Buyers who treat lithium battery documentation as a commercial discipline rather than an afterthought tend to hold margin for longer.
Shops that receive a short briefing on lithium battery documentation convert noticeably better than shops that only receive stock.
Why lithium battery documentation matters on the Zen 4

Commercial terms
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

|---|---|---|
| Carton (186 units) | Tier 1 | 7-12 days |
| Pallet (1434 units) | Tier 2 | 14-21 days |
| Container (17272 units) | Tier 3 | 30-45 days |
Frequently asked questions
