how long does it take to charge a 12 volt battery at an average speed bicycle riding?

A long time- This is a nice little unit but needs to turn nearly 1,500 rpm to make enough juice to really get to work on a 12 volt battery. It depends on the size of the battery and how discharged it is. If you had an average car battery mostly discharged and were running this on a bicycle set up it would take hours- I'd guess at least 4 to make any headway. I hope you have good legs. Mine makes 5.5 volts at 700 rpm.

Well yea, use a battery charger , or a deep cycle charger with a max of 35 amp .Most deep cycle batteries use a slow charge rate anyway which is a lower amp charger.Just keep the amp below 30 to 35 amp @ 12 volt. This is not a 24 or more system charger.

I can't give you a time but I do ride 40 minutes per day for 5days per week commuting to my job. I also do my grocery shopping by bicycle. I recharge the batteries about once a month, occasionally twice.

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.

It only takes about a hour to charge my iPhone, so I would say two to three hours to charge a battery pack depending on the size of the battery's.

Yes It has a 12 volt rechargeable for bikes with no battery or you can wire it to a battery. Battery stays charged for 5 or 6 hrs and takes about 2 minutes to recharge.

Generally speaking it takes no more than an hour to charge a completely depleted battery. With that in mind, it's good to have more than one battery for your camera.

Only if your charger can adjust down to about 1/4 of an amp charge rate, this sealed lead acid battery is designed for a low amp charge rate that at 1/4 of an amp would take about 15 to 16 hours to fully charge. Charging this battery at a higher amp rate or too fast could very well be hazardous and I don't recommend it at all. This is my third sealed lead acid battery and they usually last me about 4 years, I always charge them very slow and at a very low amperage because they are completely sealed and charging with higher amperage and or at a faster charge rate the battery could develop gasses that can't be released and the battery could possibly explode.

I only have two 650s but I know that it's a fairly fast charger. Much faster then the two port ones that often come with batteries or "package" deals. I know it takes about two or three hours for one 650 from empty. on 350s it's about an hour I think.

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.

I get about 8 to 10 hours on a charge. I also have a Mini usb charger installed on the bike so when ever i have long ride and I stop to take a break I plug it in to charge.

Sometimes it takes 12 hours, I bought 2 battery packs, They last me about a week of riding for about 40 minutes every morning before I have to change. I leave them plugged in to the light so there is always a bit of current draw even with the light off. I have ridden for > 3 hours on a charge and still used it the next day. I really like this unit even if it does take 12 hours to charge.

If you're asking how long it takes to charge this battery, approximately 6-8 hours if you use a 2.1 amp charger

This One is a good overall battery charger for the money, 3.5 amps and $59.95 It will still take like 12 hours to charge a "dead" battery, (overnight) but it's not just a maintainer or trickle charger. The .75 amp unit is mostly for much smaller batteries, the 1.1 amp is a trickle charger. Most of the old-school chargers are the "dumb style" and are 2 and 10 amp (dual) settings. a 3.5 amp "smart charge" will perform nearly as well as the old school type in speed of charge, but not harm the battery if left on it for days at a time.

Should take somewhere around a little under 80 minutes on a battery that hasn't been abused too much.
