Help for a half-wit

Is there any way of repairing a Raidfire Spear that had a pair of 3 V RCR 123As put in instead of the requisite 18650?
I made the mistake of replacing the batteries in two flashlights at the same time and put the wrong ones in the Spear. I shan't do that again!
I e-mailed Raidfire and haven't had any answer....... they're probably so disgusted they think I don't deserve an answer....... and I probably don't.
Apart from telling me to be more careful (which I deserve!), does anyone have any ideas? I don't really want to have to buy a new one, they ain't cheap!

You can replace the driver.

The driver is probably cooked and won't work anymore.

As for Edgetec, you can try PMing them via the Marketplace.

Don't know if they can help you, but you can try 4sevens.com
They sell the Spear.

Thank you gents. I've tried 4 sevens first........ see what happens.
