how long does it take to recharge when battery dies? thanks

It's depends on the charger, not the battery. And, for this battery, never let it die, or it will die forever.

When it is set to 12amp charge they say it takes 14 hours from empty. I rarely run my batteries to empty so I am able to recharge my batteries overnight - about 8-10 hours depending on how low my battery level is.

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.

Depending upon the actual age of the battery, the recharge period may take about 4+ hours or so. Unfortunately, these batteries do not last long at all and their 'charge hold' capacity greatly diminishes over time. Even with those batteries which I have labeled as 'good', I am only able to blow the leaves off half of my driveway before the battery goes dead.

Haven't really ever timed it maybe(keyword) 6 or 7 hrs, usually i'll let it recharge after it dies when i go to sleep, sorry can't give you a precise time frame.

A fully discharged battery will typically take between 20-30 min to recharge fully in my experience. Longer if the battery is hot when it is placed on the charger.

Between two and four hours. We get about two run hours per battery and yes the light turns green. If the batteries have been used and not recharged immediately, I have seen six hours to charge.

If your battery is completely dead,charge it 6 hours.I found this to be adaquate.Problem is at full charge battery will only last 20-30 minutes.

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.

I'm not quite sue--I've never used it long enough to drain a charge. My guess would be several hours. Sorry I can't be more helpful.

None of these answers look right to me.. From the manual: "It takes at least 24 hours to fully charge the battery". From the quick start guide: "Before you start, charge for 2 hours minimum". Basically: 24 hours for a full charge. If you can't wait to use it, make sure you charge for 2 hours before using it the first time.

I charge it when it's almost dead, and then it works for at least fifteen minutes the next time I vacuum. If I only use it for a couple of minutes, I don't recharge. Hope this helps.

It depends on how low the battery level is. If you are charging it from 0 then it will take about 1.5-2 hours.

ON a full charge with a new battery, between 5 and 6 minutes. Takes about 20 minutes to recharge.

No way to check battery life from what I can tell, but there is an audio indicator that lets you know when it is close to running out. Never timed it to know the exact duration, but from being completely dead to full charge, I think it takes about 2 hours.

I use my Black and Decker almost every single day in my motorhome. I simply leave it plugged in, in an inconspicuous location i between uses. I have no idea how long it would take to charge if the battery completely ran down; I've never had that happen. I tend to use it in 5-10-minute spurts and it's been fantastic. Hope this helps.

for the 18,000mAh it takes almost 24 hours (from empty to full). When I know I'm going for a trip, I plug it at 8PM (at this time, the battery is EMPTY totally)and it's usually finishes at around 8 AM (almost, sometimes half an hour more is needed)
