Battery pack poorly thought out
352685
The basic light itself is well made, very bright, and nicely variable.  Also has a nice carrying case to protect it in transit.  However, it has a very short battery life, making it difficult to use on longer shoots.

Enter the extra battery pack!  Yeah!

Unfortunately the external battery pack is VERY poorly thought out. It screws into the handle end mount.  Not a bad idea, except that the hole is not deep enough to allow it to screw tightly. Thus, it hangs and wobbles, and doesn't feel secure.

Then there is the fact you have to attach the battery power via a small external, loose cable that will almost certainly be lost.  Custom cable, short length, not attached anywhere.  Guess how long that will last?

Also, it is not possible to charge both the internal and external battery together.  You must charge one, then move the charger to the other to charge it.  Would have been trivial to allow a connection that charged both together, but apparently they just didn't think of it...

Lastly, the carrying case for the iceLight has no provision for carrying the external battery pack.  I would have thought there would a longer version, or perhaps a flap to allow the battery to remain connected, but nope. The battery is yours to store elsewhere, meaning you have to disconnect-travel-reconnect (and the connection knob is hard to turn too...).

All in all, the battery is the weak link here.  If you can get by with the standard light internal battery time, then this is a 5-star product.  I wouldn't give the battery itself more than 2-stars though.  Since this review slot is mostly for the light, I gave it the benefit and made the final a 4-star review.

Changing the battery on this unit is pretty straight forward except that screws holding the back on are very, very small and using a good jeweler's screw driver the screw heads have stripped and the next battery change will be it for these screws ( hopefully they come out ) and then it's duct tape time.  Pretty poor - didn't anyone thing about this?  For the price, I may toss this and look for another.

This is a poorly designed, terrible product.  When charging, it expands and LOCKS into the charger.  I had to break it apart with a hammer and pliers to remove it from the charger. (Without a functioning charger, the vacuum would be useless.)  I returned a second battery and the parts to the removed battery.  They tried to charge me for the broken one.  Apparently they thought only one was returned, not recognizing the parts of the second.

One battery won't hold a charge completely. I want to make sure it is not the charger before
I get angry.

Well built battery packs with an on/off switch built in

Charger is not the right one for the batteries received.

Cannot recommend this product, unfortunately.  Like several others have noted the internal battery pack circuitry is faulty.

Pros:
* Good reception of NOAA Weather.
* Excellent tone for a small monaural radio.
* Crank function charging works well and gives  reasonable amount of working time.
* Built in light is nice feature and sufficiently bright for emergency localized use.

Cons:
* After about 3 months the internal battery pack will not charge.  I replaced the battery pack, still no charge, changed the charger still no charging, finally went back to original battery pack with new charger (which btw will charge OTHER devices, as will one included with this unit).  Two bad battery packs ... think not, has to be circuitry in the radio.
* The Alert function does not work reliably.  My std. Midlands NOAA radio gets and activates on all severe weather alerts, this unit only about 2/3rds of the time for some reason.  Here I am talking about real severe weather alerts -- severe thunderstorms, tornado, high wind, flood & freeze warnings, I do not expect this unit to give specialized advisories & alerts or be S.A.M.E. capable as it is not designed or advertised to be capable of such functions.

DO NOT RECOMMEND
My advise, considering number of reviews that have had same experience as I have had -- look elsewhere for a RELIABLE hand-crank type weather radio unit.  The "lemon rate" on this one is just too high.

Battery size was correct,but after installed in the power pack and having completed several charges found the battery does not hold a charge. Now the hassel of returning it begins.

I have now had two of these in three years.  After a year or so, you ahve to replace the expensive battery pack.  I am very disappointed.

Battery recharge pack does not work. Seems like a pervasive problem. . New out of the box and the power pack won't charge at all. Waste of money. Not happy.

So when I try to line up battery you have to get it just in the right spot to check battery.
Bad Design

I put the battery pack in my Flip Video and plugged it into the wall.  Within about 5 minutes or less it said the unit was too hot.  I've tried several things such as take battery pack out, plug it in and put the battery pack in while it was plugged into the wall.  That did not help and it will not take a charge.  Afterwards I went on line to find out why this is.  Apparently, this is an inherent problem with the Flip Video that the manufactures will not address.  It's BS!

The batteries, oh the batteries... this has to do with Energizer's stupid and thoughtless packaging... imagine the + and - surfaces of the button battery both touching the same aluminum packaging foil. Actually, no need to imagine - it's exactly how they're packaged already by the Energizer factory. Dead batteries, anyone? Luckily they're small and die quickly, otherwise they'd get hot and catch fire. Who at Energizer designed this? All they'd need to to is flip the batteries in the blister, so that the only thing the aluminum-backed foil touches is the + side... no need to do anything else...  Energizer, any bright mind at your facilities willing to take that up?

The battery cannot be hung onto a pack by the loop.  It is too heavy for its own casing and the rubber gets bulled out of the plastic.  Unfortunately, this makes the battery way less useful for me
