Can I reduce the risk of battery leakage?
- Yes! Just keep a few simple rules in mind:
- Never leave dead or weak batteries in your flashlight as they are the most likely to leak.
- It is recommended that you replace the entire battery pack at least once a year, although the batteries are likely to still function normally.
- When your batteries are getting low (which you can generally tell by your flashlight being less bright than it used to be or going from bright to dim shortly after you turn it on), replace the batteries and make sure you have freshly dated batteries in all batteries installed replaced, all of the same make and type.
- Only use premium brands of alkaline batteries.
- Never use old and new batteries together.
- Never use different brands or types of batteries together (e.g. do not mix alkaline batteries with zinc-carbon or lithium batteries).
- Never attempt to charge batteries that are not designed to be charged.
- Examine your batteries carefully before inserting them into your flashlight and make sure all batteries are installed correctly (with the + and - terminals as indicated for the device).
- Check your batteries at least once a month while they're in use.
- Check your batteries immediately after the flashlight has been dropped or otherwise suffered a hard impact.
- Immediately remove any battery that is leaking, swollen, or that shows signs of damage to its case.
- Change any battery found to have passed the printed expiration date.
- When removing and replacing a damaged or expired battery, simultaneously replace all other batteries in the same set, even if they appear undamaged and have no expired date. Again, the rule is never to mix old and new batteries.
- Important: If your flashlight is going to be stored for a month or more, or if you expect to use it less than once a month, you should remove the batteries and store them separately - not in the flashlight.
- Unfortunately, given the limitations of alkaline battery technology, there is no foolproof way to prevent corrosion damage from alkaline battery leakage. But by following the simple rules above, you can minimize the possibility of battery leakage in your flashlight.
How can I open my flashlight and change the batteries if the tail cap is stuck?
- It seems the batteries in your flashlight have leaked and have caused internal corrosion. If your flashlight has been damaged by leaking batteries, do not send the flashlight to anyone for the time being, but determine/remember which brand of battery is causing the damage. After that, follow the battery manufacturer's instructions for filing a claim for damages. You can usually find this information on the battery brand's website.
How do I know if my batteries have leaked and damaged my flashlight?
- Visible signs of battery leakage are crusty deposits inside your flashlight. If the flashlight is also not working, corrosion damage is probably the cause.
- It sometimes happens that batteries get stuck while running and are difficult to remove. If this happens, it probably means the batteries have leaked and swollen. If the flashlight also does not work, it is almost certain that corrosion damage has occurred due to the leaking batteries.
- It also sometimes happens that the end cap gets stuck on the flashlight and is difficult or impossible to unscrew. If this happens (and there's no evidence of the barrel being crushed or dented), the likely cause is that one or more of the batteries have leaked. The corrosion has probably seized the end cap so that the end cap threads no longer turn and is "fixed" to the flashlight.
- In all of these situations, the likely cause is an alkaline battery leak.
Is damage due to battery leakage covered under my warranty?
- No! Battery depletion, battery leakage and damage to the flashlight caused by battery leakage are excluded from the warranty.
- However, you may be able to get help from the battery manufacturer if a battery leak damages your flashlight.
My batteries leaked and my flashlight is damaged, what can I do?
- Since the warranty excludes battery leakage damage, you should NOT simply ship the flashlight in advance
- What you CAN do is contact the battery manufacturer to see if they have a program to repair or replace your flashlight.
- Every reputable alkaline battery manufacturer has some form of equipment damage policy under which you may be entitled to have your flashlight repaired or replaced if it has been damaged by leaking alkaline batteries from that manufacturer. (NOTE: It's a good idea to write down and remember the brand name of any batteries you put in the flashlight. If leak damage occurs, it's sometimes difficult or impossible to remove the batteries from the barrel to see which ones brand they are).
- Different battery manufacturers may refer to their device damage policies by different names, and the exact terms may vary from manufacturer to manufacturer and change over time. Some of the guidelines may have specific requirements, so it may be important to contact the battery manufacturer immediately if you discover battery leak damage. Don't throw away the flashlight or batteries until you've checked to see if the battery manufacturer requires them as proof of claim.
- You should contact the battery manufacturer before sending them the damaged flashlight and be fully informed of the equipment damage claim requirements and procedures.
- You can usually find information on the battery manufacturer's website and/or on their retail packaging for batteries and/or through a customer service telephone number listed on their website or retail packaging.
