How do I know my HID Salvo Primary Torch battery voltage?

[dircavediver]

how do I know my Salvo HID Primary Torch battery should be charged to 12V, 12V or 35V??

I can see no writings on the torch or battery the torch voltage?

It doesn't say on the canister, torch head or battery?

So not entirely sure, what I should charge the battery up to?

12V, 21V or 35V, I meant. As it's not on the canister, battery or torch head! So how do I know what I am meant to charge it to? I bought it so long ago I don't know the voltage
