THAIPHUKET Posted April 25, 2013 Share Posted April 25, 2013 I got 2 emergency lights which will switch on when there is a power failure. Instructions didn´t say anything about de-charging once in awhile, which surprised me. But I see them hanging everywhere for ever. Facts is after about 2 years the led bulb will not last longer than 20 Min. Is the battery replaceable? Buy a new one? Want to have about 6 hours of light. Which brand? How often to de-charge?

Jdietz Posted April 25, 2013 Share Posted April 25, 2013 Yeah the batteries in these things usually don't last much over 2 years, especially in higher temperatures (outside). They are easy to replace through. Open the box, there will be a large gray / black brick battery. Note the voltage and capacity (Amp/hours) and dimensions, and get a similar one (same voltage critical, amp/hours may be a bit larger / smaller, in a size that will still fit the box) Amorn stocks most of them. Figure around 250 - 500B Link to comment Share on other sites More sharing options...
bankruatsteve Posted April 25, 2013 Share Posted April 25, 2013 If you want to "de-charge" then cut the power and see if they work. Batteries should be replaceable but if they don't need charging, then they don't need "de-charging". Link to comment Share on other sites More sharing options...
THAIPHUKET Posted April 25, 2013 Author Share Posted April 25, 2013 THAT´S exactly the point, they constantly on charge, power goes off, lights cut out after 20 min. That implies batteries run down prematurely, i.e. need replacement. Link to comment Share on other sites More sharing options...
bankruatsteve Posted April 25, 2013 Share Posted April 25, 2013 OK then depends on the rating of your unit. 20 minutes seems like a sufficient time for "emergency lighting" to me. Link to comment Share on other sites More sharing options...
Crossy Posted April 25, 2013 Share Posted April 25, 2013 How long did these lights run for when new? If they're down to less than 60% of that now it's time for new batteries. Sealed lead-acid batteries do struggle in the tropical environment, our UPS batteries last a couple of years before needing replacement. Link to comment Share on other sites More sharing options...
THAIPHUKET Posted April 25, 2013 Author Share Posted April 25, 2013 When new they would run for 2 hours. That would be also my expectation, the purpose is not to sit in the dark when electricity is cut. An evening without lights can be very long. That´s why I have 3 units spread throughout the house which I may switch on / off in case a longer interruption is foreseeable. Link to comment Share on other sites More sharing options...
Carlos Primeros Posted April 25, 2013 Share Posted April 25, 2013 If you really have LED light bulbs they will easily last for about 10 hours on battery. If you have halogen bulbs they last only about 1 - 2 hours. To deplete the battery just unplug the emergency light until it fades. Then plug it in again and let it recharge. This should be done at least every 2 or 3 months if you had no longer power cuts in the mean time. If you have halogen bulbs you can easily replace them by 12 volt LED bulbs. I also use a LED emergency light for mobile use. I just carry it around and put it where ever I need light. And it lasts for the whole night if necessary.

lopburi3 Posted April 26, 2013 Share Posted April 26, 2013 Nobody mentioned LED from my reading. Our led cookie size units last forever on simple AA cells and just have a few around house for such times. Understand upcountry they would get more use but LED in any flavor is far better that what you apparently have. As said those batteries do not last long in the high heat of Thailand.

lopburi3 Posted April 27, 2013 Share Posted April 27, 2013 And I just read again and did not see it - reading as light bulb in my mind it seems. Still can not believe that is all the service he gets from LED as most of those lamps are very low wattage. Have never seen LED emergency lights but have not been looking for them so guess maybe they are out there. Link to comment Share on other sites More sharing options...
THAIPHUKET Posted April 27, 2013 Author Share Posted April 27, 2013 Well, thank you all for enlighten me my lights. Honestly, I don´t know what bulbs they actually are. they should really not be LEDs, because those ought to run for ever. Sorry for confusion and thanks again!

THAIPHUKET Posted April 28, 2013 Author Share Posted April 28, 2013 Gentlemen, I owe you a proper answer= 2X20W Halogen lamps. It is certainly worthwhile to see if LED battery powered lamps with the same light output are available. I love good light! Link to comment Share on other sites More sharing options...
Crossy Posted April 28, 2013 Share Posted April 28, 2013 You should be able to get LED replacement lamps (check out ebay), 5W units should give around the same amount of light. Link to comment Share on other sites More sharing options...
