Battery Vendors:
These vendors have been used by many vapers.


A great calculator for vapers:

Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

Where known, the ratings set by Samsung, Sony, LG, or Panasonic/Sanyo will be used.

Any battery from Samsung, Sony, LG, Panasonic, or Sanyo can be a lower grade battery or a fake. Only buy from a known, trusted source of genuine batteries. Even then, there are no guarantees.

Carefully research any battery you are considering using before purchasing.

Testing batteries at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved, understands the risks, has the proper equipment, and takes all appropriate safety precautions.

These tests I do only note the estimated ratings for the batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time This is one of the hazards of using “rewrapped” batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

Golf Cart Battery Basics

Golf cart batteries are the life-force behind your electric golf cart.

Golf carts run off of what are called deep-cycle batteries. Although they look similar to normal car batteries, deep-cycle batteries serve a completely different purpose. While both are lead-acid based, deep-cycle batteries provide a steady current over a long period of time, whereas car batteries provide a very large current over a short period of time. This is because golf carts, like other electric vehicles, derive all their power from their batteries.

One battery is not enough to run a golf cart. Instead, they use battery packs that consist of multiple batteries. Individual golf cart batteries usually come in 6-volts or 8-volts. The combined total of the voltage from each battery makes up the total golf cart voltage. For instance, a 36-volt golf cart probably has six 6-volt batteries. And a 48-volt golf cart probably has either eight 6-volt batteries or six 8-volt batteries. And as you can probably guess, the higher the voltage the longer the run time and the greater the power.

If your batteries aren’t charged, however, it doesn’t matter how many volts your battery pack has, it’s still not going to run. The type of golf cart charger you would need depends on the total number of volts your battery pack has. A 36V golf cart requires a 36 volt charger, and a 48V golf cart requires a 48 volt charger. If you have a 36V golf cart and later decide to upgrade to a 48V golf cart by adding two additional 6V batteries, you can either purchase an additional 12V charger for two new batteries, or you can replace your 36V charger with a 48V charger, just so long as the voltage from the charger corresponds with the voltage of the batteries.

To keep your golf cart running strong you’re going to want to charge your batteries after every use. Most new chargers are fully automated, which means they regulate the current so that you do not over-charge your batteries. If you have an older golf cart charger that is not fully automated you would want to set a timer to shut off the charger after your cart is fully charged. A good rule of thumb is to charge it for at least twice as long as you drove it.

Another thing to be aware of is how well your batteries are performing. To keep them in tip-top shape requires proper care. You should be aware of such information as proper water levels and cleaning techniques. The most proactive thing you can do is to take proper safety measures and set up a weekly or monthly schedule to make sure everything is well maintained. One weak battery will bring down all of the otherwise strong batteries to the weakest battery’s level, so it makes sense to keep them all properly maintained.

If you want to customize your cart with electrical golf cart accessories, they too will be powered from your golf cart batteries. There are several ways to hook them up, and the best way depends on your particular situation. Most electrical golf cart accessories are 12V accessories, which means they run off of twelve volts. The quick and easy way to power your accessories is to hook them up directly to two of your 6V batteries. But this can cause an imbalance in your battery pack, especially if you have too many accessories requiring too much wattage. At this point it would be better to add a separate auxiliary battery strictly to run your accessories, or a converter to evenly distribute the power from all of your batteries to your accessories.

When it’s time to replace your batteries you will need to think about proper golf cart battery disposal. To recycle your old batteries you should take them to a retailer who recycles old batteries for resale. Most retailers that sell lead-acid batteries also take used batteries because it is required by most state laws. Recycling your used golf cart batteries is good for the environment and good for the health of you and those around you.

Basics of Virtual Server Management

Servers are the backbone of every successful business organization and without the support of servers the business can never flourish. However, today, the business organizations are not opting for the physical servers but are instead looking for virtualizations of their servers as it saves on time, investment and power. Physical servers are huge machines that use up a lot of space and power and the cooling costs of such machines are also substantial. Therefore, facing such situations, the best way to move ahead the business would be to opt for virtual server management.

Virtualization implications division of a single physical server to several multiple, which in turn stores the data and has the capability of working as any physical server or system. To maximize resources, several companies are now opting for management, which utilizes one physical dedicated server and sets up several, which co-exists independently of the main system. The process involves analyzing and maintaining resources so that high performance connection of the network remains established through the working of the server. To ensure constant performance of the server, have to be established tactfully and their number should never impede the performance of the main server.

The disadvantage of creating virtual servers is that if the number of exceeded their limit then it would seriously affect the speed of the network and affect the proper functioning of the main physical server. To avoid such situations management always comes in handy. It checks the constantly and ensures that they are even spaced and allocated, so that optimum speed and performance of the entire network remains active through.

Virtual server management also involves checking on the performance of the entire system regularly. Several performance tools such as software and applications can be utilized to keep a check on the system. Issues such as traffic visiting the websites, speed and security of the server and the networking between the clients and the employees can be regulated by employing server management features. An image of the system can also be created to note any glitch or error that might come up in the server unit. Dedicated servers have to meet the needs of the end users and clients, so you have to keep your server functioning properly and to enable that virtualization of your servers and its management is essentially required.

The advantages of virtual servers can not be over emphasized, as with time have become a serious component of big companies and today one can not imagine hosting multiple physical servers when there is the option of setting up. Virtualization serves the purpose of cutting down costs while at the same time it speeds up the process of transferring data from one server to another without cutting down on the speed of the network. It also allows several applications to run simultaneously over multiple servers without disabling any individual server. Today, organizations must definitely opt for management, as it is the best way to ensure the growth of their business entity.

Garage Door Opener Basics

In times past, having a garage mean that each time the homeowner returned home and wanted to put the car in the garage, someone had to get out and raise the door and then lower it after the vehicle was parked. Of course, electronic garage doors extremely, became more popular and the doors could be opened easily, by merely pressing a button. However, these electronic doors did not include the safety features and advances available today such as pressure and obstacle sensors, a selection of motor impulses or the ability to change directions with the touch of a button. Today, there are many styles and features to consider when selecting garage doors and openers. Here are a few things to keep in mind when making your choice.


Perhaps the most common style of door opener is the chain drive opener. These work much like a bicycle chain and can be quite noisy. They are available in to to hp hp models and cost anywhere from $ 150 to $ 200.

For a quitter drive, you may opt for a screw-drive door opener. These have very few moving parts so they make less noise. In addition, they are easy to install and require minimal maintenance. Average price for the screw-drive is $ 150 to $ 225.

If you are willing to spend a bit more ($ 200- $ 300), then you may want to choose the belt-drive opener which uses a long rubber belt to raise and lower the door. These doors are essentially maintenance free.

One of the most recent types of residential door openings is the jackshaft opener which is mounted on the same wall as the overhead door, so there is no need for an overhead track or drive system. These heavy residential doors make almost no sound whatever; however, you will need the services of a professional for installation.


Originally, all garage doors worked on AC powered motors, but now garage doors primarily use DC as it allows for better speed control and assortment of features. Of course, these DC motors require a conversion from AC power and they use less power than an AC motor. However, manufactures install a battery backup, in the event of a power outage. It should also be noted that while the door springs are responsible for lifting the door, you will want to have a door opener with a higher horsepower rating as they have the ability to start and stop the garage door there should ever be a problem with the garage door's spring system.


When it comes to protecting your family, there is no such thing as "doing too much." One way you can protect your family is with a garage door opener that requires a code to raise or lower the door. The latest in this technology is called a rolling code. This rolling code means that each time the transmitter is operated it sends the code to the receiver but also creates a new code for the next operation.


Learn the Basics of an Unsecured Loan – Is It the Best Choice?

Personal unsecured loans allow a person to borrow money for whatever reason they need it for. This includes, new businesses, or even high-end things like jet skis or a new car. Once one has decided to get a personal unsecured loan they should definitely explore their options.

First, one should understand what it means when a loan is not secured. This means there’s no necessary collateral in order to get the loan. If worse comes to worse and the loan isn’t repaid then it’s less risky because no property will be lost or held until the loan is paid. This is more comfortable for most as there are no immediate consequences giving them time to recover.

The majority of the risk rests with the lender with a personal unsecured loan. If the loan goes south they have nothing to sell in order to recoup the amount. They will undoubtedly pursue the funds and even take legal action against the borrower such as garnishing wages. Due to the high level of risk, borrowers should expect higher interest rates. Plus, the loan acceptance does depend on credit somewhat. Good credit equals lower interest, and bad credit may produce either higher interest or even a co-signer.

Here are the basic types of personal unsecured loans:

Signature loans – these are the most simple variation of an unsecured loan. They are only secured by the borrowers promise to pay. They can be obtained at credit unions and banks, and the money can be used for anything. The fact that they’re installment loans mean they are borrowed and repaid in fixed, monthly payments.

Even better, a signature loan can help a person build credit and get even better future rates. So, it is by far the best personal unsecured loan on the market.

Credit cards – another popular method for a personal unsecured loan is by obtaining credit cards. A bit on the riskier side, they still give the borrower a pool of money to use as they wish with no questions asked. A credit limit will be assigned and the borrower can charge as much or as little as they please and pay it back monthly.

The only downside to credit cards is that they fluctuate as far as interest rate, with some having an initial low rate as an introduction and then it goes up after an amount of time. It’s easier to spend with credit cards because swiping them for purchases is super easy. Offers exist online and via the mail.

P2P or Peer loans – Consider a P2P loan as a form of personal unsecured loan. Basically, it is borrowing from an individual and not a bank or other traditional lender. These loans are available online, on specific websites and there is a chance that no one will actually pick up the loan, but it’s worth a try. They are installment loans with a fixed rate and they do look at credit.

Student loans – Student loans are personal unsecured loans made just for education funding. They’re a good choice because they carry features that aren’t readily available through other means. They offer flexible repayment, grace periods and more. Some don’t even concern themselves with credit score, they only care if the borrower is a student.

These loans are available through the financial aid office of the institution being attended. The professionals there will help the student through the application process and explain all the ins and outs.
