Is there a prescribed time for recharging. I was once told that if the battery is left on line to charge beyond full charge, overcharging ruins the battery.

Basically an old wive's tale at this point. Modern chargers mostly detect when a battery is full and stop charging (or drop back to just trickle charging). I wouldn't worry about it unless a manual for a device specifically says to disconnect the charger after a full charge. There's so much mythology and repeated nonsense out there about batteries, chargers, and how they work!

I am quoting from the instructions that came with the battery: "The charger and batery pack can be left connected with the green LED glowing indefinitely. The charger will keep the battery pack fresh and charged."

Amazon's questions & answers IS NOT the best place on the internet to get technical of common sense answers to anything higher tech than a crow bar.

Black & Decker says that these batteries can be left on their chargers indefinitely without overcharging. I don't know what would happen if you used a different charger.

I don't know if there is a prescribed time for recharging; I don't remember any info on that with the batteries. I keep my batteries on the charger until I need to use them again, which is about once a week; sometimes longer. I've had my batteries for several years and they still work great.

As far as I know a good charger shuts off after full charge is done! If you don't have your speck papers for your charger go on line to your charger & copy the instructions! or call their help #!

I can't answer this, in my case once I use the charged battery, my charger/battery will not take a new charge, is this a normal problem and should I look for a charger?

I have only had it a short time but if it gets a full 7 hour initial charge then run it down, which takes about 15 to 20 minutes, then re charge mine runs at least 30 minutes now and should go longer as the recharge process is repeated. I hope this was helpful

I think the initial charge is longer. I believe it should be 16-24 hours. When it runs down we just plug it in at night and it's ready to go in the morning. The charger will stop when it is full, and not overload it.

I have not incur a problem with the battery. Not sure what was your problem beforehand or how long you have had your phone system. Often I have left one of the phone off the charger for a day or so, or someone in my household unplugs so to use the outlet. I re-plug and it recharges fine. I appreciate knowing customer service is prompt & attentive to your battery issue.

I bought the car in January- the battery was fully charged and I still haven't charged it at all! My kids don't drive it everyday but it does get used about 3 times per week for about 20 minutes at a time. I read that over charging the battery tends to cause problems so I've been waiting for it to run out before I recharge it. I'm totally shocked at how long it's lasted.

I've had my since February 2013 and haven't had to do anything to it. I don't think the battery is being overcharged- I think it turns that function off once it has full capacity. There is one side with half the plugs that is battery and surge protected and the other side with the other half of the plugs with surge protection. I am very happy with this item- it's plugged in under my desk and I've never had to touch it.

My battery is never fully depleted and I have my charge timer set to start charging at 1 AM. By the time I wake up, usually round 5 AM, it's completely charged. We're talking about a battery with about 30% capacity to start with.

I bought an extra batt from Amazon as well and both batteries, the one that came with the phone (tmob s3) and the recently purchased one work ok. I think the newer battery is flaky. It only shows about 80% after charging overnight. Doesn't say that there's circuitry in the charger to prevent overcharging, but it does take a looong time to charge. IMO the slow charging cycle extends the life of the battery. There's a battery charge indicator light that shows RED when charging and BLUE when the battery is fully charged. Hope that helps.

I left mine plugged in for 24 hours then disconnected it and used it. There was plenty of charge left and I won't plug it in again for a recharge until it slows down.

Probably an hour for a full charge. I finally had to replace my battery because it would not hold a charge. Pull yours out and see if it is bulged in the middle. If so it is bad.

I would charge it for a full 15 hours before using it. They usually come partially charged, so doing a full charge is the best way to be sure.

No, it is a trickle charger (compared to a "smart" charger that automatically turns off) and will overcharge. Please read the instructions, which clearly state not to leave it charging for more than 8 hours. Only charge until the light turns green, then stop. They also state to recharge immediately after use, and every 30 days if not used, to keep it topped up. Apparently they don't want you to leave it in a discharged state.The battery seems to be the weak link in these rather crappy quality lights. I would do everything I can to follow the instructions and not do anything that might damage the battery or shorten its life...

I generally come home in the evening @7:00, plug in my charger, and my vehicle is topped up when I leave @5:45 the next morning. I try not to charge until I am 4 bars or less -- so have never started at zero. 3 1/2 hours isn't sufficient to top up the car, even if I start with 4 bars. Allegedly I am supposed to be able to do a full charge from zero in 4 1/2 hours. I'd guess it's more like 6. Stu

I change when battery life decreases fo a few hours of "on" time, or when transmission becomes garbled. Before charging a new battery, put it in the radio and discharge it all the way, Then charge it normally, usually for around 24 hours. DO NOT OVERCHARGE ! This significantly reduces battery life. I charge mine the same length of time it was on. I have been using this battery in my radios for several years, and this is what I do.

Excellent! I get a strong 2 hours before recharging and at that point I'm plugging in only asa precaution due too my own personal habits. Of course I do recommend Running on battery power so add not to over charge the battery when plugged into AC.... if overcharging is possible with the batteries these days. I'm old school.
