How long does it take to fully recharge it from a dead battery?

Typically, from a fully depleted battery to a full charged battery it will take 45 minutes. It will not harm the SBU to leave the charger attached overnight though.

It seems to take about an hour (the charger turns off automatically) I usually leave it plugged in for an additional hour in case it needs to do any charger balancing.

I also leave it plugged in when not in use, keeps the battery from depleting during the loong winter

I usually get a full charge on an empty battery in 4-6 hours. I have two so Irotate them.

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.

It takes a while to fully charge it would be around 80 percent from a dead battery.it does its what it says.

Mine had a partial charge so I can't be sure, but I think about 4 hrs to fully charge.

It was fully charged as soon as I turned mine on. I don't know how long it takes to fully recharge after the battery has been depleted

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

In my experience it can take anywhere from 1-6 hours. I have several things I use this type of battery and am not sure what batteries came with this light. The charge time will depend on the capacity of the battery (higher mAh will take longer), how much it has been discharged, and condition of the battery. As a battery ages it takes longer to charge. Completely discharging the battery before recharging will also reduce battery life. Sorry I've gone a bit long, you can go to batteryuniversity.com to learn about all batteries.

I haven't monitored to see exactly how long it takes to charge from dead to full charge, but I think 8-10 hours should be enough.

The only truly to know that the batteries are fully charged is when the LED on the charger is green. It takes about 3 hrs. to fully recharge.

To fully charge the battery when it has no battery left at all, it takes about 2 hours to get fully charged.

Mine was nearly fully charged when I received it. I have not run the battery completely dead during any single use yet, so I can't be certain. I would guess it should fully charge within an hour.

it takes a long time, im not really sure because i usually charge it with the adapter it came with, but if i had to guess i would say around 16 hours or longer.

About 2 1/2 hours if standard battery is pretty dead. My xl battery takes closer to 6 hours to recharge.

usually takes about 3-4 hours but it depends if you let the battery drain all the way or recharge it when it has half charge. I have not recharged it for awhile and I have use it to restart cars, inflate bikes tires and inflate sport gear these past months. I do check the battery meter to see how it's holding and recommend to keep on a shelf above the ground and recharge at least every month if you use it often other wise it holds charge without recharging that much.

I recharge about 1-2 weeks. I wait until the battery drains completely and it basically shuts down on me. Then I recharge fully. It's a lot longer than every few days.
