FAQ Suggestions for Parts & Accessories

• Q: What’s the best type of replacement battery to buy?
  A: Use the same chemistry (alkaline, NiMH, lithium) the flashlight was designed for. Rechargeables are great for frequent use; disposables are good for backups.

• Q: How do I know if I need a replacement bulb or a new flashlight?
  A: If the body, optics, or battery still work well, replacing the bulb can restore brightness at lower cost. If the housing is damaged or corrosion has set in, a full replacement may make more sense.

• Q: Are all chargers compatible with all batteries?
  A: No. Make sure the charger supports the battery type (size and chemistry), and that it has necessary protections (overcharge, short-circuit, temperature). Using an incompatible charger can damage the battery or worse.

• Q: How often should flashlight parts like switches or O-rings be replaced?
  A: It depends on usage and environment. Rugged or wet conditions degrade seals and switches faster. Inspect regularly, and replace parts if they fail to seal or if throw/power drops drastically.
