Borrowing on the technology of cellphone batteries, E Cigarette batteries are some of the most efficient, best-performing examples of present-day battery technology out there. Many take less than an hour to charge, and, depending on size, have hours of life between charges.
The two most common styles of batteries are the cigarette-sized ‘510’ and the cigar-sized ‘eGo.’ As you would guess, the larger ‘eGo’ battery has both a longer time between charges, and a stronger output than the ‘510’ battery. In general , you can expect to get about an hour of ‘on’ time with the 510, and two-to-four hours, again depending on size, from the eGo battery. Likewise, you can use a larger, higher output (read ‘more vapor’) atomizer with the eGo battery than with a 510 battery, which generally can drive nothing larger than a cigarette-sized atomizer.
The Logistics Side of Battery Selection
The two most important factors in choosing one battery style over another is ‘What’s your preferred type of atomizer/cartomizer/clearomizer’ and ‘What usage patterns fit your lifestyle’. This latter factor bears some explanation. Unless you opt for disposable electronic cigarettes, you’ll need to recharge your ecig batteries. Here are the options available to you now.
By far the simplest but probably the most expensive alternative, vape on it til its exhausted, then toss it.
A cigarette-sized pack of usually 3 or 4 cigarette-sized batteries. When you’re on the go, as you exhaust a battery, insert it into the pack, and it recharges. The pack is capable of recharging 3 to 4 times. Then at night, you plug the entire assembly into a home charger and charging pack and all batteries recharge completely in one operation overnight. This option is ideal for folks on the go, who aren’t’ in one place and don’t have access to wall chargers during the day.
Everywhere we look these days we find USB data and power sources. On our computers, on wall chargers for phones and other portable devices, even in our automobiles. ECig battery designs of all sizes include this ‘pass-through’ feature. Means you can recharge your battery directly from any of these sources. Also means that with a 3-foot USB cable, you can begin vaping on an otherwise dead battery beginning the moment you plug it in.Home charger: The traditional option. You disconnect your battery from it’s atomizer assembly and connect it to a charger. After an hour or two, your battery is fully charged and ready to use throughout the day.
Battery Quality vs. Price
Like with E Cigarettes, higher price doesn’t always equate to higher quality. The best rule of thumb is “Go-with-what-you-know”. You might add to that, go with what the reviews are saying. A consistently reliable choice of battery is the JoyeTech brand. And a factor in describing battery capacity is the mAh rating.
So What’s a mAh?
mAh stands for milli-amp-hour and is a pure rating of how much vaping power a battery provides. You can safely assume a 1400 mAh battery will give you a bit more than twice the hours of ‘on’ time than a 650 mAh battery.
Most e cigarette batteries contain some sophisticated electronics known as ‘voltage regulators’ These circuits guarantee you a constant amount of power throughout the life of a charge. (Unregulated batteries would provide a power ‘curve’ that starts out high and then diminishes over the charge life giving you good strong vapor output immediately after charge but dwindling down to weak output toward the end of battery charge life.) By keeping output constant, you can actually predict charge life and how it varies depending on two other factors: voltage output and atomizer resistance.
Two rules of thumb:
If you double voltage output, you will halve charge life. Many batteries are ‘variable voltage’ i.e. you can set the voltage output. More voltage = more vapor.If you double atomizer resistance, you will double charge life. Many atomizers are available in various resistances (measured in Ohms). Lower resistance = more vapor.
