Ordering

What do buyers ask before ordering the LR43?

How long does a LR43 battery last?
LR43 is rated 86mAh and runs for 640.0 hours under our published test — test conditions: 10KΩ 24h/day to 1.2V @ 20±2℃. Service life in your device depends on the load and the cut-off voltage, so send us the device and we will size the cell for it.
What is inside a LR43 battery?
The LR43 is built from Manganese, Graphite — a Zn-MnO₂ system at 1.5V, rated 86mAh, about 1.48g. The material list belongs to this model's technical file, and the MSDS for the chemistry comes with the documentation set.
How long can a LR43 be stored?
Our storage statement for the LR43 reads: One years under normal storage conditions. Keep the cells in the original packaging; the storage and transport guidance that applies to this 1.5V Zn-MnO₂ model goes out with the shipment paperwork.
Is the LR43 rechargeable?
No — the LR43 is a primary (non-rechargeable) cell. Charging a primary cell can cause leakage or rupture, so replace it rather than recharge it. If your application needs recharging, ask us for the rechargeable range.
Which documents come with a LR43 order?
Each LR43 consignment carries its own EU declaration of conformity (reference TQ-EUDOC-LR43-20260701) and an MSDS. Transport documentation is issued for the consignment as the destination market requires.
How do I order the LR43 in bulk?
Send the model, your annual quantity and the packaging format. First orders start from 50 cartons per product line, and printing on the cell, blister card and box is done in our own plant with your logo and barcode.

How do I get LR43 wholesale pricing?
