what kind of rechargeable battery to use? I used 1.2v but it only have 2 bars and last about 10 mins?

I do not have a problem with mine staying charged. I use Energizer batteries.

heavy duty alkaline. if it only lsts 10 minutes then you have a bad sender should last you at least 1 to 2 monthsif not going off constantly

I don't know anything about a rechargeable battery. I'm not sure how long the cord is but it is pretty long. Personally, I wish I would have bought the higher output one though. This unit doesn't blow air hard enough to dry my V-Rod properly. I have to keep going over areas.

Ken J was real close. You have to take 80% of the atv battery's AH rating (which, by the way, can be anywhere from 4 AH to 36 AH). You never discharge a lead acid battery 100% (12.0 volts open circuit is discharged, 12.72 and up open circuit is fully charged). They have a very high resistance to recharge when you discharge them completely. So a 5 AH battery has 4 AH available. Drawing 3 amps for one hour is 3 AH. So that battery would only last about an hour and 20 minutes give or take a few. A 36 AH could go over 9 hours. So it ultimately depends on what AH battery you use.

I'd say mine lasts just under 3 hours at the lowest power levels. The battery is easy to remove, so you can always buy a second battery to double your life.

Don't do it! The excess voltage would surely burn something out. (If they even fit.) There are numerous suitable "double A" batteries that will work, including many rechargeable ones.

If I'm understanding the question correctly, it uses 110 volt power to recharge the battery. I wish mine worked that way, but it doesn't hold the charge for more than about 1-1/2 minutes when using it.

You use the included orange USB cable to plug into any USB charger (like the one that came with your phone) or USB port on a computer/laptop. Because of this battery's size you'll want to use a charger capable of putting out 2 amps, though anything 1 amp and above will suffice. More amps = shorter charging time. I believe the specs say it'll take 7 hours at 2.1A to charge so roughly double that time at 1 amp.

The BRB72n comes with a 1650mAh built-in rechargeable Lithium battery, which lasts about 3-4 hours depending on the device you use it with. The battery can also be used as a mobile power supply for other devices (e.g., smartphones). Other than the built-in battery, the BRB72n can also be powered through its power adapter, a laptop USB port, or a micro USB car charger.

Hi. The replacement batteres are Li-ion rechargeable 18650. These are 3.6v, should be 3000mA. These are readily available with a charger through Amazon- I bought several sets and have had good luck.

Try a couple of rechargeable eneloops. From memory with a total capacity around 4.8Wh I might get over 4 hours shaving. So a little over a Watt power draw - not as powerful as a corded mains unit. With disposable AAs I have seen a 60 minute runtime mentioned - but you might expect more like 4 hours from fresh alkalines. Power goes down with voltage drop - so expensive Lithium [1.8V] AAs will give the most powerful shave. (Eneloops have a fairly constant 1.2V, compared to primary batteries that might drop from an initial 1.5V to under 1V with use. I have experimented with a robust 3.2V LiFe AA, & dummy, as this averages a stable 1.6V - although with a reduced ~2Wh capacity. I recharge this single 600mAh cell weekly). PS: As a followup make sure that the base is properly seated - this can be troublesome, & effect battery connection.

since this question popped up, i ran mine for the last two hours and it's still going strong. i'm using the Sony battery (actually a generic copy), so your mileage may vary based on battery type. i don't think this was fully charged when i started, but only has one bar left now. but it did run full blast for 2 hours.

This is a 12V battery, but for running even a small winch that still pulls ~40 amps I'd go for a bigger battery. This one is rated for 18 amp-hour (hinting it'll supply 18 amps for 1 hour, or 9 amps for 2 hours, etc) and I don't think it's a good idea to pull more than that 18 amp rating for more than a few seconds (like to crank a car).

You have a lead acid sealed battery, where it is best not to discharge it more than half forgetivity, before recharging it fully. Usally it will last about an hour in solid surface or about 15 minutes witha single kid. With 2 kids about half fully discharged.

Any rechargeable AA will work. The ones with the higher mAh ratings will likely hold a charge longer. I've used different brands without noticing much difference. I would just avoid the cheapest, unknown brands.

The battery is a CR2032 3V. It is one of those flat round ones. I had the balls on for about 5 hours and they still had power. I don't know how long they are expected to run on one battery. The batteries I bought for the couple that needed them were over $5.

A 12 volt 7 amp battery works best ! If you try to use a larger size, it probably will not fit inside the control panel and not charge as fast or all the way.

ITS NOT A BATTERY!do NOT replace it unless you know what you are doing.some facts;1) its a 3.3v super cap at .22farad2) its underdesigned for even 3.3v use; its DANGEROUS FOR 5V USE!3) it takes a while to charge up but not as long as a true rechargeable battery4) it will last a short while (hour or so) and not days or weeks; by design5) do NOT use on arduino 5v systems unless you power this from 3.3v or less!
