Checking and Charging Motorcycle Batteries

March 16th, 2008 by akeger

How are Motorcycle Batteries Rated?

The amp/hour (AH) capacity is the basis for rating motorcycle batteries. For example, a 12AH battery can produce one amp of current flow for 12 hours, or two amps for six hours. In order to calculate the amount of time needed to use up a fully charged motorcycle battery by turning the lights on, we have to take power in watts, and divide it by voltage, which gives us the current draw in Amps. Therefore, a 72 watts beam and tail together, divided by 12 volts equals a 6-amp draw. So in 2 hours, the 12AH battery is dead.

Checking Motorcycle Battery:

If you decide to check if your new motorcycle battery is done correctly, follow this actual factory-recommended service procedure.

If the battery is not a maintenance-free type which doesn’t have a vent tube, unwrap the battery, unkink the vent tube and snip about a half-inch off the end. Fill it with electrolyte midway (between the high and low level markings on the case) and leave it undisturbed for one or two hours. Remember, the battery will still be at only 65% of full charge at this point. Add electrolyte again if required.

If your battery is a refillable lead-antimony type, it should be charged at one-third of its rated capacity in amp/hours for four to five hours to get it to full charge. Maintenance-free type battery should be charged with a constant-current charger that can drive the charge with as much as 16.9 volts. This should be closely supervised so as not to exceed full charge.

Next, recheck the electrolyte level and add water if required. Let the battery cool so the case contracts enough to fit into its typically tight little holder. Run the new breather tube, if the battery comes along with one, carefully through the original factory routing.

Things to Remember when Charging the Battery:

1. First of all, it is important to remember that Red is positive and Black is negative in order to avoid any accidents such as short-circuits and nasty shocks.

2. The charger should be compatible with the motorcycle battery, and give a greater output than the battery voltage but not too high.

3. Make sure the connections are clean and the electrolyte is at the upper level, and don’t fill the cells up to the very top of the battery.

4. You can either use an optimizer on the battery which can effectively switch off the battery when it’s charged and prevents overheating, or disconnect it manually.

5. It is recommended to put your battery on charge every two or three weeks.

6. An upper and lower level battery should have all the cells on the upper level, not over and never under the lower level.

7. For topping off the low cells, use only distilled water.

8. The minimum charge for a new batter should be at least for 8 hours.

9. If you have a dry battery, fill the cells slowly and leave the battery for around half an hour.

Harley Davidson King of Motorcycles

December 30th, 2007 by akeger

Harley Davidson. The name means motorcycles. In business for over a hundred years, the company is universally acknowledged as the manufacturer of some of the world’s finest motorcycles, and justly so.

Beginning in the mind of William Harley and the backyard of his friend, Arthur Davidson, the pair created a ‘motorized bicycle’ that has evolved into the standard for fine two-wheeled transportation.

Founded in Milwaukee, Wisconsin, their first bike didn’t even have enough power to make it up the small hills of the town without pedal assistance. The pair were undaunted. Within a few years they were producing vehicles for the military fighting WWI and it’s been the standard for military and police bikes ever since.

From 50 motorcycles produced at the original factory in 1906, the company has grown to produce millions that are sold around the world.

‘Harley’, ‘Choppers’, ‘Hogs’ and other nicknames became attached over the years. Choppers are bikes that have a front fork angle extended, moving the handlebars back. ‘Hogs’ came into being when live pigs were ridden around on the back seat after winning a race. But whatever you call them, Harley Davidson motorcycles - with the exception of a short-lived hiccup in the 1970s - have always been the gold standard of bikes.

Their large, powerful engines and distinctive pipe sounds make them recognizable before they even round the corner. Seeing one cements the impression that the viewer is watching greatness drive by.

They figure prominently in the major rallies, the Daytona in Florida in March, the Laconia in New Hampshire in June and the Sturgis in South Dakota in August. Thousands of Harley owners attend and there are inevitably a few dropped jaws at the sight of some of the customized versions.

The Harley Owners Group, H.O.G., founded in 1983, now has over 1,000 chapters with over a million members worldwide. Many don’t even own a bike. But the passion for this exemplar of motorcycle engineering is the same, even so. You don’t have to own a Rolls Royce to appreciate one as an example of excellence in motoring design.

Beyond the bikes themselves, there are co-branded jackets, helmets and hundreds more items carrying the Harley Davidson winged emblem recognized the world over. Though they contribute a modest percentage to the over $5 billion in annual revenue, the advertising is priceless. As if anyone needed to be told that Harley Davidson makes motorcycles!

There are thousands of Harley Davidson forums online - three times as many as there are for Yamaha. One of the few serious competitors for the crown of motorcycle design. BMW, Victory, Honda… many strive - some come close - but Harley Davidson remains the champion. A title they are unlikely to relinquish anytime soon.

After all, there’s only room for one at the summit of the tallest peak.
