We have sold over 20,000 LightCaps and have seen very few warranty defect problems. The two problems that we have seen are a failure of the switch, or the battery fails. If the battery fails (standard rechargeable AAA) it can be replaced.

Most problems can be fixed without replacement, however. If you are having problems with your LightCap200 or LightCap300, here’s what we suggest

Place the LightCap in very bright sunshine for several hours. If possible, place it outside since some types of window glass can reduce the type of light needed by up to 80%. Then take the LightCap into a very dark room and see if it works. Many times the batteries need a real “kick” of bright light to get them charging after being fully depleted.

Another quick way to check the LightCap is to hold it right under a very bright incandescent light bulb (2 inches – 6cm away – not one with neon bulbs) for 30-45 seconds. Then take the LightCap into a dark place and try the switch. If it doesn’t work, then the problem is either the battery or the switch.

We have found that 95% of the time when problems are reported, it is because there simply isn’t enough charge in the battery. A long soaking in direct sunshine almost always fixes the issue.

Every time the LightCap battery gets totally depleted, it decreases it’s useful life. The batteries are generally good for up to 300 cycles; up to 500 if they aren’t fully depleted very often, or under 200 if they are.

Try to keep your LightCap charged up as much as possible. The batteries will drain naturally around 1% per day (as with all rechargeable batteries). Try to store your LightCap on a windowsill or an area with some natural light when not in use.

In the rare instances when you have a defective switch or battery, just drop us an email and we’ll fix the problem.
