HT lights

[Reservoir Dawg]

I bought a 25 light LED light made by HT from Fleet Farm. I put four rechargeable AA batteries in and lit it up at first I was very impressed but then the LED lights began to burn out after a few hours of use.Some of the lights actually exploded narrowly missing my eye.

I exchanged the first light I bought only to have the same thing happen. Has anyone else had this expirence ? Should a person not use rechargeable batteries in an LED light ?

Have a few of them and never had a problem. It could be the rechargeables but I don't see why they would do that.

Email the company and ask about the batteries. I have only used regular alkalines in mine.

juice is juice - how's the light supposed to know where it comes from? Did you get them wet?

Regular alkaline batteries put out 1.5 volts. Most rechargeable batteries put out something less, like 1.2 volts, so I doubt it's the batteries. It seems unlikely you'd get 2 bad lights, but it's possible.

I've got the second light right in front of me I tested it in my office, after a couple hours the lights started burning out. This light has four lights in the middle and 21 around the outside.The four lights in the middle still light but there are only two on the outside still working and two exploded. On this light you push a button once and the four middle lights come on,twice and the outer lights come on, and three times all the lights come on.

As metrojoe stated, rechargable batteries put out a slightly lower Voltage than do non-rechargable. The problem with that in this case is with the lower voltage, the amperage is increased to overcome the resistance. I am guessing that the LED lights in the HT light can not handle the amperage that is being used to power them at the lower voltage. Thats just my two sense.

I have the same light and have not had any problems at all.

I also have only used Duracell's though.

[Reservoir Dawg]

Thanks, I took the back cover off and under the battery it says 1.5v and if I look at the rechargeable battery it says 1.2v. I actually measured the battery with a multimeter and they measured 1.3v

I also have the 48LED light from Northern at it works fine with the same batteries.

Dumb question, but doesn't the voltage drop on a regular battery as its used.

[kywest]

No it doesn't because the way that the batteries are connected, they are connected in parallel and in a parallel circuit voltage stays the same throughout. What changes is the amperage... long story short, you would probablly do yourself good just getting some disposable. Speaking of that, Home Depot has a pack of 36 duracel AA on sale right now for 12 bucks. Just a thought

IMO HT = junk

[eurolarva]

You are correct. When regular batteries start to die the weakest in the parallel chain will draw the others down so when the batts get old eventually you will hit 1.2 volts with regular batteries and the higher current would do the same thing.
