Any ideas regarding longevity of the rechargeable batteries? Anyone here had these plugged in for months/years and they still work in a power failure

I have no idea if they wear out. A red light is on while plugged in, not sure if that is a "power" light or a "working" light.

they last pretty long for me. It really depends on the type of item your using these batteries for. But for me they always last at least 5 hours. Theyre pretty reliable for me. They also take like a day to fully recharge for me, i go to sleep & when i wake up their fully charged.

You need to recharge them until the little green light on the charger goes out. If you use them constantly (easy to do with a trimmer) they only seem to run a short time--20 minutes or so. I haven't tested my theory, but it seems that if I give them frequent, short breaks they seem to perform longer. (I use them in trimmer, chain saws, and drill.) Of course, if they're old they may just be worn out.

Following the other answer: if the unit is not new, then, like rechargeable batteries, they eventually die. The power cord should be changed out to see if it's the problem.

Yes. When our power went out then came back on they stopped working maybe because of a power surge when the power came back on, which doesn't make any sense. They just stop working. This is a flaw or a big coincidence Yep about 6 months they lasted.

My guess is that they last as long as any rechargeable better that recharges via electricity, which is not forever. I did have an issue with the Ambient solar-powered radio. Their response to me may be helpful if you are using this battery for that radio: "The solar collector was meant to be a battery life extender but was never intended to fully charge the battery. Thus, we recommend you "hard charge" through the USB port once every few weeks. Best practice is to leave it plugged into the power port all of the time. It will not damage the radio." per Ambient

Mine were the same, tried new batteries, that didn't work so I sent them back. Too costly and I got frustrated with them. I really liked them when they worked!

The rep at Cyberpower instructed me that the batteries have a typical shelf-life of about 3 years. I would presume that when your power-supplyied outlets stop functioning, that's when the battery has failed/died. Mine just happened to get hit by a power surge and hastened the process a little bit. I noticed this when the items plugged into the power-supplied outlets just stopped working, while items plugged into the regular surge-protected outlets continued to work (e.g., lamps, speakers, etc.)

I use rechargeables. The problem is I forget to turn the lights off, and the batteries die.

We have never replaced the rechargeable batteries. Make sure that the blue light is on when charging.

Same problem; worked great for about 2 years... then started getting a lil drop out.. now they won't recharge at all. TOAST. For $50 I'd expect more.

My experience with these is once they will not hold a charge they need to be replaced no matter the age or use. Check the warranty?

Well, Chad. The ones i bought work Perfect, No Issues. Sounds like your problem could be a Ground Issue? I guess i would hook them up, one at a time, to a good 12volt battery. makeing sure if the problem follows the same light. then...take that light apart and look for any possible Faults?

Haven't let them go fully dead. I normally recharge every 15-16 hours. They always last from one charge to the next. No problems with life.

Oddly, these batteries remain on the list (as of Aug 1 2015) even after I've put a check in the "rechargeable" filter (to stop seeing non-rechargeables). They show up as "rechargeable" even though (based on the answers here) they almost certainly aren't rechargeable.

I've got this same set on my bike and I use rechargeable batteries in mine. They usually last about a month to a month 1/2 before having to be recharged. I've been using the same batteries since I got this set of lights about 4 years ago.
