Can i take the battery out, bring it home, charge it and then use it again ? How long does it take to charge from say 20% of capacity to 80% ?

The battery is removable & can be charged when not in the bike. I would say it should take about 1.5 - 2 hours to charge it to 80%. I hope this helps you.

The battery can be removed from the bicycle and charged without being attached to the bike. It can take from 4 to 8 hours to fully charge the battery, the incremental progress is not known or has yet to be determined. I hook my battery up to the charger every other night for about 6 hours; owners manual says you should never charge it longer than 18 hours continuously.

We usually charge it over night after each use to ensure a full charge for the next time. But after 6 to 8 hours it's good to go. I like to let them run it completely down and then charge it just so the battery doesn't get a memory.

You can charge it in about 2 or 3 hours. I found a trick that if you make sure it stays cool, it will charge quicker and discharge slower. Not a bad battery.

Charge it for a while and then try to use it. You can use it while it is plugged up

Charge it for over 24hrs prior to first use. It goes back to its home base automatically after work.

Yes, charge it for a few hours. After that you are good to go for at least 2 full charges and a 3rd partial charge.

The first time we charged the battery before we used it took 18 hours. After that we just charge it overnight. I think it was recommended to charge it 5-6 hours after using it.

You probably do not want to have this plugged in all the time because that will "overcharge" the battery and damage it, so you only want to take it to it's "full" level and stop. If you want to have it charged every day to be "freshly charged", after an initial charge you could leave it plugged into a timer that comes on for 20 minutes a day, that wouldn't "overcharge" it and yet would give it a brief charge.As far as current used, the charger probably delivers 1/2 Amp at 12V which means at 120V house power it only draws 0.05 Amps. So you will hardly see that on your power bill.

It can take between one and a half to two hours to charge the battery if charged when about 15% of the charge remains. I usually do not let mine completely run out but based on the time it takes for 85% of the battery to charge, I would estimate two hours and twenty minutes to two and a half hours for a full charge.

Yes. I leave it plugged in since I use it at home. If the battery runs out, it will take some time before it charges enough to use again. I expected it to work as soon as I plugged it in but it didn't.

I don't know exactly, I just plug it, and leave it. whenever I remember it, I take it off the charge, and it'll be fully charged! If you put it in charge with less than %5 battery life, it'll take longer to be fully charged. I usually charge it whenever I use it, I plug it before I sleep, next morning will be fully charged!

No it's not a battery that you can just take out, you must have knowledge of taking it apart and replacing it with a new battery. It's a built in battery using small cords

The biggest caveat is to pay attention to the directions. 21 hours, completely deplete the battery then put it on for another 21 hours. Have to do this 5 times to complete the batteries fully charged memory. I can guarantee you the majority of the complaints are people who didn't take the time to read the directions and/or follow the directions. After those 5 charges up to you what you do. I'm a fan of the old battery technology of retaining batteries memory by ALWAYS completely depleting a battery before I place it back on the charger. These new batteries don't require it, but my method has yet to fail me. :) The biggest caveat is to pay attention to the directions. 21 hours, completely deplete the battery then put it on for another 21 hours.

Leave it in the charger as long as you want and it won't hurt the battery. It takes about 9 hours to fully charge. Therefore, I suggest you have two batteries.

Not sure have to probably take it into to radio shack or some place like that. I know the battery has a very short life. I have to re-charge mine almost every day even if it has not been used.

I haven't try yet but I think you can't, it is better not charge device wile the battery is charging, since the battery just need 7 hours to be fully charged.

When I first received mine, it took about 20 minutes to an hour to get a full charge. By the time I finally just threw it out (less than a year later) I would leave it plugged in all day and get about 30 seconds of use.
