## Questions & Answers

**Q: Is the battery removable?**
A: My Neiko LED work light stopped charging. 
You can open it by pulling the large bottom grip straight down. Takes some grip strength to pull it off. 
Then you can remove two screws to access the pcb boards.

**Q: Is this product water resistant?**
A: The micro USB port on the bottom isn't covered, so the light isn't water-proof.  The grip is rubberized though, and might do fine hanging upright in the rain.  I haven't tried it outdoors myself though.

**Q: What are the dimensions of the light itself? I only see package dimensions.**
A: Just under 15 inches total length not counting the folding hook. Folded open the hook adds another 3 inches. The light section is 5 inches long. The bottom handle is 1.5 inches wide.

**Q: Can we buy just the charger as we have lost ours?**
A: I don't know. chargers are very specific to the battery being charged, so you can look on the info panel of the charger and see what the ratings are. You can pick up another charger that matches the ratings, but whether it works or not, ur on your own. I would pick up another charger from the company
