Once charged, how long will the LuminAID's batteries hold a useful charge without recharging?
367879
The LuminAID Solar Light uses a lithium-ion polymer rechargeable battery, similar to the battery in most cell phones. Before storing for an extended period of time, we recommend charging the product in direct sun for 6-7 hours. Once fully charged, the battery will hold a majority of its charge and light up after over a year of being in storage. Like all rechargeable batteries, it does lose a small percentage of charge over time when it is in storage and not being used. In order to ensure the product is fully charged when you need it, we do recommend taking it out of storage and recharging the product in direct sun every few months. If there are any other questions/concerns, please reach us at orders@luminaid.com and we would be happy to help!

Well... The first day I had it it stayed lit for almost 9 hours. The next time after charging for days I only got 2-3 hours. Now it won't light at all. I suspect I got a bad battery. But I thought I would put it out in case I was not alone.

I fully charged mine and used it at night, for about an hour each night, for over a week without running out of power.

A few hours. I have yet to read of anyone who has gotten more light. It works long on first use only, then very short battery life.

My battery lasted about for over 14 hours (staining deck). It recharges using a standard ridgid 18v lithium charger.

Well my first dlight 300 wouldnt hold a charge hardly at all.It would stay up if the light was on but go down quickly if not in use.They sent me a replacement whithout having to return the defective one and from the very start,new lantern is working great.I practically charge it up daily and use it at night.The longest i went so far was 4 days and only on a partial charge.The battery was fine.Another note is that the new light seems to charge a lot easier than my first one.Hope this helps!

Probably around six or so hours. If the battery is not fully discharged it could be less. Will stop blinking when charged. It does not hurt to leave it it the charger like older batteries. If the battery is hot when put into the charger a red light will come on. Will not start charging until the battery cools some

If you started with a fully charged battery and ran on hi setting how soon, if ever, would the power degrade to the point where brightness was affected? I have never tried it so I don't know for certain. The spec sheet says it will put out 5000 lumens (brightest setting) for one hour 15 minutes.The charger output is 2 A.The battery rated output is 5200 mAH.The charging time Is about four hours. So you could calculate but. if it didn't work you could use back up battery pack(s). You have me curious now about what kind of an application would allow you to have it plugged in to AC four hours.

yes. I work night and use them on a regular basis. I don't have to recharge them for 3 or 4 days unless I needed to use them for a for a 4 or 5 hour stretch above my normal usage. Meaning, that these batteries will hold a charge a lot better than the aaa battery pack (about 4 times) or the 18650 cell (about twice as long) and will give you a whiter light for a time in the ultrafire flashlights.

Not sure you really don't want to let li-on batteries discharge completely. It kills their lifespan. It takes about 4-5 hours to charge from 10-15%

Not a expert but my experience w/ similar type emergency lighting batteries is 2-4 yrs. They actually would last longer if receiving a discharge/charge every 3-6 months. Probably why people report these go bad after 3-4 yrs because they rarely get discharged/charged. If you do buy a spare keep it in a cool place and that will help the shelf life.

With proper use (i.e. charging during the day and operating during the night), the batteries should last longer than 2 years. Like any rechargeable battery, over time the charge may not last as long as with say a mobile phone, but the lights are on periodically so I have not noticed any degradation over the 2.5 years I have had 4 of my lights installed. Finally, the bulbs are actually 60 LEDs which are attached to a circuit board and cannot or do not need to be changed. The operating life of the LEDs are about 20,000 hours far exceeding the life of the light.

I've had my lamp for 6 months. I've never tested the battery for time duration, but it definitely longer than 2 hrs. If I use it a lot, I plug it up whether it needs it or not, just so I'll have it bright for the next use. Also pay attention to the recharge instructions. It's pretty tough, I use it for MIG welding as my shop isn't well lit and my vision isn't as good at 60 as it once was...HTH,Russ

I did a test on mine which is about 18 months old. On a full charge, 3 lights illuminated on the side, it lasted 27.5 hours. It was still illuminated but about 1/2 the brightness of a full charge. You can easily get 24 hours of useful light out of this.

I used it for about 30 minutes/day for 7-9 days before I had to recharge it. I've had it plugged in now for about 5 hours and it's already back to 100%. I'm sure the charging time could be much lower. I just didn't have a reason to unplug it to find out. It's a great lamp. I'm very pleased with it.

Once charged, it lasts at least 24 hours. You have to hang it on the charged, so no, you can not charge it while using it. No additional batteries are required except for what come in it (sealed).

Hey Derrick... I charged it when I received it on April 30. I use it on average 2-3 hours per evening. I use the back light function every 30 minutes or so and the unit is in standby during the 2-3 hours of use. I turn the unit off each evening. I have not yet had to charge the battery.

I charge mine every month the battery last quite awhile. I use the light as I'm coming out of work at night..I have purchased several of these for my children.

probably a couple of hours if substantially discharged. The batteries I'm charging are not totally discharged - I just top them off every couple of weeks to keep them fully charged and it takes 15 - 30 min.

I believe the charger stops when the batteries are full and just maintains them as is. Not sure how long term usage will affect them. However, I have been impresses at how long the rechargeable batteries will last without using them and just sitting in the flashlight. I'm pleased so far with their brightness (like day light to me) and how long they last without recharging. I originally bought the batteries to use with my bike on 25 mile long night rides. It took about two or more batteries for that in order to maintain the brightness I desired.
