This teardown is not a repair guide. Gently pull the battery spring from the tail cap by slowly tugging side to side at the base of the spring until it clears the edge of the tail cap. Spring can get away from you after removal, be careful to maintain what do korean girls like hold-points on chane spring during removal.

Twist head cap counter-clockwise until head cap becomes completely loose from the barrel of the flashlight. Twist face cap counter-clockwise until face cap is completely loose from head cap. Hw face cap has been removed from head cap, the reflector and lens can chage removed from the head cap. Badges: 0. I received my mini maglite from a vendor quite a few years ago, while I was a technology coordinator for a school district. After my mother became legally btateries, it was one of the things I gave to her for assistance.

Long story short, it has been in my home again for a few years. I got it out yesterday, when I needed a flashlight. I found your instructions helpful in affirming my experience in disassembling the light. Unfortunately, nothing I could do would remove the batgeries. I was thinking you might include instructions for the process of removing corroded batteries and bringing the light back to life. It is presently soaking in a glass of hot how to change batteries in mini maglite with a little soap.

Same situation for me. Read online that white vinegar might help dislodge the battery - I'm going to try that.

If you do try that, do so with proper safety precautions. I'm not sure what the resulting chemical reactions will entail. Me too. Same issue with batteries that I cannot remove.

They're there for 6 or more years! I how to change batteries in mini maglite remove wverything insiste the battwries, but there arw battefies parte do them I could not remove.

Drill a screw into the bottom of the battery. Then mimi it out. I used a variation on this technique:. There was a lot of corrosion. Your breakdown instructions stop before that point. I shook it gently out the bottom of the flashlight for complete cleaning. Be sure to check the orientation of the silver connector tab. It can fall out and needs to be put back into the slot.

Introduction

Hold the mini Maglite down on the newspaper with your left hand. Hold the pliers in your right hand. Grip the jaws of the pliers around the sides of the battery cap. Twist the . Remove the head of the flashlight to expose the bulb. Gently pull the bulb from the base of the Mini and discard. Pull the spare bulb out of the tail cap and insert it into the socket of the base. Reattach the head of the flashlight, reinsert the battery and place the tail cap back on the base. It is for use only by factory-certified technicians performing authorized warranty service on the Mini Maglite® Flashlight and/or other Mini Maglite® Flashlight components. Page 2: Troubleshooting 1. FLASHLIGHT FAILURE: Check the lamp and the batteries with the meter.

All of our published ANSI-standard performance data Light Output, Beam Distance, Peak Beam Candlepower and Run Time are based on testing with alkaline batteries; and when we ship these flashlights with batteries, the batteries we include with them are alkaline.

We do this because the designs of these flashlights are optimized for use with non-rechargeable alkaline batteries. NiMH rechargeable batteries in these sizes typically have a somewhat lower nominal output 1. Also, the discharge curves of NiMH batteries typically differ from those of alkaline batteries — so the two battery types may behave differently under load.

That said, the flashlights will operate with NiMH rechargeables, and use of NiMH rechargeables will not harm the circuitry nor otherwise damage the flashlights in any way. The degree of difference is hard to predict. We have noted variation in the quality of NiMH rechargeable batteries on the market, and if you choose the best-quality NiMH batteries you might find that any performance shortfall is, for your purposes, not meaningful.

In normal use, the LED should last for the life of the owner and should never need to be replaced. The explanation for these statements is a little complicated. So the filament breaks. Instead, what typically happens to an LED is that its light output extremely slowly, and extremely gradually, declines with use.

Nobody would claim, however, that an LED is completely bulletproof under all conditions. It should go without saying that one who uses his LED flashlight as an impact tool or a fire-poker is looking for trouble. Excessive operating temperatures could also threaten the longevity of an LED.

It sounds like you may be using the incorrect replacement lamp for your flashlight. Make sure to buy the correct lamp for your flashlight. If you are unsure of which lamp to use in your flashlight do not hesitate to contact us at 1 When you cannot remove the tailcap to change the batteries, it is probably that the batteries leaked and caused corrosion inside. Mag Instrument does not warrant against battery leakage.

When this happens, it probably means that the batteries have leaked and are stuck inside the barrel. Oftentimes, batteries will swell before leaking, causing them to get stuck inside the barrel. All alkaline batteries are filled with a caustic material that can damage corrode any device, including a flashlight, if it escapes from the battery cell. Given the limitations of alkaline battery technology, there is always some risk that a battery might leak under some conditions.

There are a number of specific reasons why this might happen. One is a defect in the battery, or physical damage to it. Another reason has to do with the fact that all alkaline batteries have a self-discharge rate, causing them to gradually weaken and die even if they are in a package on a shelf, or in a device that is not used.

Leaving dead batteries inside a device can cause battery leakage and resulting corrosion damage. And misuse of the batteries e.

But if you follow the simple rules above, you can minimize the possibility that batteries will leak inside your flashlight. Visual signs of battery leakage and crusty deposits corrosion inside your flashlight are a sign of leakage and damage, and if the flashlight is non-functional, this corrosion damage is likely the cause. It sometimes happens that batteries become stuck inside the barrel and are hard to remove.

If this happens, it likely means that the batteries have leaked and have swelled up, and if the flashlight is non-functional, corrosion damage from the leaking batteries is almost certainly the cause.

It also sometimes happens that the tailcap becomes stuck on the flashlight and is difficult to unscrew. Battery exhaustion, battery leakage, and flashlight damage caused by battery leakage are all specifically excluded from your warranty. You may, however, be able to get help from the battery manufacturer if a battery leak damages your flashlight. See the next FAQ below for details. What you CAN do is contact the battery manufacturer to see if it has a program to repair or replace your leak-damaged flashlight.

Every reputable alkaline battery manufacturer has some form of device damage policy under which you may be eligible to have your flashlight repaired or replaced if it has been damaged by leakage of alkaline batteries that came from that manufacturer.

NOTE: It is good practice to write down and remember the brand name of any batteries you put in the flashlight. If leak damage does occur, it is sometimes difficult or impossible to get the batteries out of the barrel to see what brand they are.

Different battery makers may call their device damage policies by different names, and the exact terms may differ from one maker to another and may change over time.

Some of the policies may have special requirements, so it may be important to contact the battery manufacturer without delay if you discover battery leak damage. And do not discard the flashlight or the batteries before finding out whether the battery manufacturer requires you to submit them as proof of claim.

You should communicate with the battery manufacturer before you send them the damaged flashlight, and should confirm exactly what their device damage claim eligibility requirements and procedures are. For your convenience we provide the following website links and contact numbers through which you can get more information concerning battery-leak-damage policies and procedures of various battery manufacturers.

Please understand that the battery manufacturers are companies separate and independent of Mag Instrument. The above battery manufacturer contact information, current as of late September , is provided to you as a courtesy but is, of course, subject to change by the battery manufacturer.

The ANSI Standard defines four basic performance categories, and prescribes official logos for displaying results. The following table lists the categories, and for each one indicates the unit of measure, the official logo, and the basic meaning of the category:. Judging from questions and comments we receive, the distinction between Light Output and Beam Distance is a source of some confusion.

A flashlight can have a very high Light Output measured in lumens , and yet have a very short Beam Distance measured in meters. And the opposite can also be true: A flashlight can have a very modest output in lumens and yet can be remarkably effective in lighting up an object very far away. Why is this possible? Because Light Output is simply a raw measure of the rate at which a light source generates light — i. It tells nothing about how well or poorly that light is gathered and directed.

Beam Distance, on the other hand, is a measure of the maximum distance from which an optimally focused flashlight will cast a useful amount of light on a target.

A quarter of a lux can roughly be described as the light level provided by a full moon in an open field on a clear night. In fact, to get a high Light Output score, a flashlight would not even need to have a reflector or lens, at all! Since the beginning, Mag Instrument has prided itself on its beam-forming optics — the quality of its precision-designed and precision-crafted reflectors, and the versatility of its spot-to-flood beam focusing mechanism.

High-quality optics can also play a role in slowing battery consumption and prolonging Run Time. As LED technology continues to advance, the number of watts of power consumed per lumen of light generated goes down; but it is still true to say that the more lumens you want, the faster you will consume battery power.

Each of our incandescent lamps was designed and developed with only one purpose in mind — to operate optimally in the particular flashlight for which the particular lamp is designated.

We do not, however, test for or publish current-draw or wattage figures for the lamp itself, as these are not ANSI performance categories. Just as we do not publish any claim, we also do not guarantee any rating, as to the current draw or the wattage of the lamp you reference. Voltage in volts times Current in amperes equals Power in watts. Thus, if the voltage drop is 4. You would, however, need to look to the accuracy of your own equipment and the correctness of your own technique.

Mag Instrument is not in a position to warrant the accuracy or the typicality of whatever current-draw, voltage-drop or wattage numbers you might obtain. It is against Mag Instrument policy to provide engineering advice to persons seeking to use Mag Instrument parts or components to build non-Mag devices. And of course we do not warrant, endorse or recommend any such use or any such non-Mag device.

You can, however, obtain approximate wattage, current-draw and voltage-drop numbers for the lamp in its intended operating environment by following the procedure described in the answer next above. Be the first to hear about offers, specials and giveaways. Sign up Now!

Yes, just follow these simple rules: Never leave dead or weak batteries in a flashlight, as they are the ones most likely to leak.

It is good practice to replace your entire set of batteries at least once a year, even if the batteries still seem to be functioning normally.

When your batteries get low which you can generally tell by noticing that your flashlight is less bright than it used to be, or goes from bright to dim shortly after it is turned on , replace the batteries — and be sure to replace the entire set at the same time, with freshly-dated batteries that are all of the same brand and the same type. Stick to premium brands of alkaline batteries Never mix old and new batteries together.

Never mix different brands or types of batteries together e. Inspect your batteries at least once a month while they are in service. Inspect your batteries immediately after the flashlight has been dropped or otherwise has suffered a hard impact. Immediately remove from service any battery that is found to be leaking or swelling, or that shows signs of damage to its casing or terminals — e. Remove from service any battery found to be past its marked expiration date.

When removing and replacing a damaged or date-expired battery, replace all other batteries in the same set at the same time, even if they appear undamaged and are not date-expired.

Again, the idea is to never mix old and new batteries together. Importantly, when your flashlight is to be stored for a month or longer, or when you otherwise expect to use it less than once a month, you should remove the batteries and store them separately — not inside the flashlight. In any of these situations, the likely cause is alkaline battery leak damage.
