Batteries lasted 4 months, disappointed to see lead acid batteries inside
on December 9, 2013
I purchased these from Amazon in July 2013 and they lasted about 4 months before the "rechargeable" batteries gave up the ghost. They sat for a few weeks as I wondered what to do about them, they would not stay on for more than 2 seconds and would not function even if they were plugged in.
Since I did not have the box they came in I was not sure I could return them. So I decided to open them up and see what was wrong with them. I was really disappointed to see they have lead acid "rechargeable" batteries in them. My only guess as to how mine stopped functioning was due to my not keeping them plugged in all the time and the batteries going completely dead. Lead Acid batteries do not like to be discharged completely over and over again. A lithium battery would have been better suited for this application in my opinion.
So I removed the batteries and rewired my units so they will function without a battery in them but have to be plugged in. At least they work now. Where I place them on my patio there is a power source so I am happy.
I am thinking of replacing the lead acid batteries with some 12V lithium Ion batteries this winter. I would urge the manufacturer to consider this as an option, I would spend more for the better battery technology. Especially in an application like this one.
