Answers of usual questions relate to miner's lamp:
I want to know how many times can I charge the lamp?
Our lamp can be recharged for more than 1200 continually; the life is more than three years long.

Does your battery need to add electrolyte during using?
No there is no need to add electrolyte when you recharge the battery, our lamp is made from the most advanced li-ion battery, it is sealed and free maintenance.

.With regard to the charger can you tell us what the led colors are indicating?
 It is red for charging and green when the battery is fully charged.

Can we use our old chargers to charge your lamp so that we can save the cost while we improve our mining lamp?
Our charger is designed for our 3.7V voltage li-ion battery.
The working theory is: first it is recharging in constant current 1500mA, when the voltage of the recharged li-ion battery is reaching the recharge voltage DC 4.20 ±0.05V then switch to constant voltage. When the current is less 100mA, then it is finished recharging.
If the chargers of your customers work like this, maybe they still can use their chargers, but we can make sure to the lamp can work normally.
And if the recharging is less charging, that will no problem accept work less hours, we prohibited over charge otherwise the battery will terminal damage. So the working life is shortage.
Our charger can protect from over charging.
We have considered this question to make the customers can use the old chargers. So we have a module of ZLCD-34, to see the detail, please read this page:
ZLCD-34
You can still use your old charger rack by replacing this module. You only need to remove the old circuit and replacing our charger module.
After changing this charger rack, one charge module can recharge for 34 unit lamp. If you want to recharge more lamps, you can use more modules.

Yes. We have made two circuits to make tow kinds of chargers of 220/110V AC single phase 50/60 Hz. So please advice us what is the voltage you need, so that we can offer the correct chargers for you.

At the beginning the mining lamp working voltage is 4.2V, at the end of working the lamp is 3.6V.
The bulb working voltage is 3.6V; currency is 0.7A of the main filament, 0.6A of the assistant filament.
