What is the self-discharge rate? How long do they stay charged sitting on shelf?

I charged mine up about 6wks.ago used the cleaning brush today for about 15 minutes when I got thru it showed no signs of needing recharging that's pretty good in my opinion.

Not really sure on either of these. I know an overnight charge is more than enough to get it back to full and my daughter hasn't been able to completely discharge it within one day's time yet.

Probably a month or longer. I've had them out for 6 weeks and they were working.Excellent solution. I keep the unopened ones in the freezer to keep them fresher.We use two in the pantry, rotate one each two weeks, so there is a fresh one onone shelf, while the other is two weeks or older.

I have forgot to check mine on charging for up to a half an hour over time limit and have yet to harm it. Just to let you know, I just checked mine and it is still charged after sitting for two months without being checked.

Yes. We use it for our security system so they are charged. We don't pull from them unless we lose power then they are backup to system. It's like people are saying seems like a trickle charge. I think directions even mention to charge overnight. But as I said we install ours and leave them.

I haven't used them enough to know; they tend to sit around so the charge does deplete over time. However, they recharge quickly so I am not concerned if they last long or not as I have 2. Pat

I used an external charger and left it charging overnight so I'm not certain how long it actually took. I was surprised that it came to me fully discharged but after that initial charge it's been working normally.

Since they are rechargeable, I have no idea how many times you can charge them. However, we've never had them discharge fully but only use them a maximum of 3-4 hours at a time with no problems.

I try not to leave them too long after they are done charging, but the times I have (a couple of days)there wasn't a problem. I wouldn't leave them in for weeks, though. I have read somewhere there is a very slight drain over time.

I've had mine a while. I usually keep it in my purse for emergencies. The longest I think I've kept it without using it was about 2 weeks and it was still charged, so I'm sure it can last longer (I just haven't had to test it for more than that).

They should be ready to go. You can re-charge them anytime you want. Buy fresh products from C2CSAFETY INC

Leon, I've had mine go for 3 full days with intermittent use maybe 3 to 4 hours a day, before I've become afraid they are going to be dead and charged them.

I've watched TV for over three hours and they still stay charged. It would be a good idea to just return them to the charger when done and then they are already set to go next time you watch TV.

Don't know, but a long time. Mine has never needed recharging. I have not used them a great deal, so this is probably not very helpful.

I use it for 1-2 hours a day and i do not charge every day. i don't pay attention to how often i do charge it, but it is not a lot. So far, it has never died out. you will not be disappointed if you buy them!

I have it as a back up in an alarm system, and they have lasted one or two years before needing replacement. It is constantly kept charged by the alarm system. Then we get a call from the alarm company when it no longer stays charged, needing replacement.
