Enercell flashlight, how to change batteries

Operation flashlight

Flashlights are now sometimes relatively complex tools that are not always easy to operate at first glance. Especially those who hold a modern high-performance flashlight in their hands for the first time will be enthusiastic about the possibilities, but sometimes also be overwhelmed with the operation, especially if the operating instructions are only in a foreign language.

If you have not had much or nothing to do with modern flashlights before, read the operating instructions, provided they are in a language that you understand. And even if that is not the case: In most cases, a simple knowledge of English is enough to understand what the manufacturer means, and many instructions are also illustrated.

It often happens that we get supposedly defective returns, but they work perfectly and were only operated incorrectly. So before you send back your supposedly defective lamp, you should check a few points.

Battery / rechargeable batteries

First of all, it is important to check whether the rechargeable battery / battery is suitable for your lamp.
The following are the three most common types:

You cannot mix these with each other, and as is easy to see, the size of 18650 Li-Ion batteries alone does not fit into lamps that are suitable for AA batteries. This is also better because Li-ion batteries have an operating voltage of up to 4.2 volts. You could therefore easily destroy the lamp electronics of a lamp designed for 1.5 volt batteries through overvoltage! Therefore, when buying the right batteries / rechargeable batteries, make sure that you are purchasing the correct type.

You should therefore also pay attention to the usually specified operating voltage of the lamp. This is particularly the case with CR123 Li-Ion batteries and 16340 rechargeable batteries (these are sometimes also called CR123R. named) problems arise. The CR123 has 3 volts as operating voltage, but a freshly charged LiIon-16340 has up to 4.2 volts. If two CR123s fit in one lamp, as is often the case, since instead of the required 6 volts with 2 CR123 batteries, up to 8.4 volts can quickly come up with two 16340 batteries, which in turn leads to the destruction of the lamp electronics can. Usually, however, you can also operate lamps for 2 pieces CR123 with a 18650 Li-Ion battery.

Another important point: Pay attention to the polarity when inserting, that is, insert the rechargeable batteries the right way round! This is because not all lamps have reverse polarity protection, and it may well be the case that the electronics of the lamp are immediately destroyed by a battery that is inserted the wrong way round. In most cases, however, the lamp will simply not turn on. In most lamps, the battery / rechargeable battery is inserted with the positive pole facing the lamp head. But not for all, then this is usually indicated on the lamp or in the battery tube.

Therefore, please check whether you have inserted the battery in your lamp the right way round before you send it back to us as defective.

While flashlights previously only had a single switch, many current lamps are operated using a switch combination. Usually the lamp is switched on at the back, while the brightness levels are selected by a switch on the side. We often get lamps back where the customer has tried to turn on the lamp with the side switch, which is solely responsible for switching through the light levels. Pressing the side switch does nothing until the rear lamp has been switched on first.

But there are also lamps where the functions / light levels are on a switch. Here you can usually reach the other modes by quickly touching the switch (before it clicks into place), and you can save them by pressing the switch fully. However, it is always advisable to take a look at the user manual / operating instructions to find out how to access which functions.

So please check whether your lamp also has a switch on the back before you send it back to us as defective.

Image 2: Some lamps have a switch combination. First the lamp must be switched on with the rear switch (1). The light level is then selected with the switch (2) on the side.

Other lamps are also switched on with the rear switch and the brightness levels are selected by slightly loosening / tightening the lamp head.

Please first check whether the brightness levels of your lamp are selected by loosening / tightening the lamp head before you send it back to us as defective because it supposedly only has one light level.

Image 4: With some lamps, the different light levels are selected by slightly loosening or tightening the lamp head. To do this, take the lamp head between your index finger and thumb and turn it.
