how long can I store the batteries after charging?

I had some store for over a month, when I used them they were fine. This is a great charger. I recommend it.

Not long, 2 or 3 months at the VERY longest. This is a trait of the NiMH batteries, NOT the brand. Personally, I would top-off any battery I was planing to use during an electricity free vacation, no earlier than a week beforehand, in order to have the most juice on hand when you need it. This is from my personal experience with a wide selection of brands and a wide variety of battery ages. Everready, on the other hand, claims that NiMH batteries in general will loose 50% of their charge in six months. I expect this may be the case under the very best laboratory, tempature and humidity controlled conditions. Not under normal conditions, like your camera case, electronics drawer, or your battery shoe box. Now... While I've never seen a STORED NiMH battery hold a charge that long, I HAVE found that using them in something that draws a small, but constant current, will give you a MUCH longer shelf-life than charging them and then storing them. Depending on what they are in, I've seen them last up to a year or longer.

It depends in what do you gonna use them. In a hand lamp about 6 hours without turn it off. But they are the best. :)

yea it will be fine to leave it plugged in and the batteries in. they are lithium ion type batteries the same kind in laptops and cell phones. so they will charge up then the charger will just keep them charged till your ready to use them, i dont know about long term though like over a week or two probably wouldnt be great for them.

I cannot answer that fully. I have not left them on long enough for them to lose charge. I have the manual at home. So I would guestimate 15 hrs? Maybe more, maybe less. Best bet is the manual, what it says, but if you don'g actively correct them for a long period I would think it would hold charge a little longer

Do not store the battery in the trimmer after charging. There is a small current draw that will drain the battery.

probably a couple of hours if substantially discharged. The batteries I'm charging are not totally discharged - I just top them off every couple of weeks to keep them fully charged and it takes 15 - 30 min.

It can take 5-24 hours of initial charge time for these (depending on how big the battery is) and the manual for the unit I have says "for best performance, recharge at least every 3 months or after each use." The recharge time after that first one depends on how long it's been and how drained the battery is possibly talking another 24 hours.

Generally, it takes a few hours. I sometimes leave them on the charger over night for the first charge. No worries. It's well worth the wait.

Several days, just like a rechargeable toothbrush. I don't leave the rechargeable items like phones and etc. on the chargers, just charge them, and run the charge down then recharge and they seem to last for a long time.

It depends on if you're using them continuously. I would say you can get about 8-10 hours (though this varies). You can extend the life by removing the batteries when you don't need to use them. You can also buy replacement batteries, but they tend to be expensive so I would recommend buying new ones.

I followed the instructions that came with the kit and charged batteries for about 18 hours. They took the charge and have been working good for several weeks now with occasional recharging.

I put fresh batteries in before a trip I took for 14 days & I ran it every night. The batteries are still good but I am taking an extra set of 4 with me on the next trip......just in case!

Make sure you wait 15 minutes after using your battery before you charge it. If you charge it right after you use it they won't last long. You have to let them cool down.

So far after I charge the battery it will last about 90 minutes. I have not had any issues with the battery.

Once charged, it lasts at least 24 hours. You have to hang it on the charged, so no, you can not charge it while using it. No additional batteries are required except for what come in it (sealed).

Recharge these anytime. In fact, best to NOT let these run down entirely, as these (unlike Ni-Cad) have no 'memory.' Mainly don't overcharge. These take about a 2 hour charge, and overcharging in an attempt to bring them up to full capacity cause battery 'stress.' You can get the full, more scientific answers to your questions if you Google. Also, remove from charger after charging.

After first charge , you can charge the battery for 6 to 8 hours from initial charge

Per the instructions chart, the left and right bays are independent from each other. You can charge as little as two AAA batteries of 850 mAh in less than an hour to eight AA batteries of 2700 mAh in six hours. If you use the discharge feature, then you're looking at about four hours to discharge one to eight AAA batteries and up to 14 hours to discharge one to eight AA batteries, then add charging time.
