look for PowerGenix brand batteries to be on sale
Detroit Janyuary 14, 2009; Surprisingly, it’s been nearly two decades since the last major advance in battery technology. For non-geeky Acer UM08A51 Battery types, this would have been the commercialization of the Lithium Ion cell. This Laptop Batteries type remains the industry’s standard for pure electric vehicles because it can deliver more power over a longer period of time at a lower cost than any competitive technology.
Manufacturers carry out battery tests on brand new equipment within protected environments. In Batteries in a Portable World, Mr. Buchmann observes the HP Compaq Business Notebook nx7300 Battery as used by consumers in everyday life.
The battery handbook addresses the strengths and limitations of the modern battery. It illustrates which battery chemistry is most appropriate for each application. You will learn about charger technology, battery maintenance to prolong battery life and methods to restore weak batteries with a IBM ThinkPad Z61t Battery analyzer.
The typical life of a Li?ion battery is 300 to 500 discharge/charge cycles or two to three years from the time of manufacturing. The loss of battery capacity occurs gradually and often without the knowledge of the user. The function of the battery analyzer is to identify weak batteries and “weed’ them out before they become a problem.
In spite of this success, don’t look for PowerGenix brand batteries to be on sale at your local Radio Shack or under the hood of a Toyota Prius anytime soon. While the company already manufacturers their NiZn cells for use in power tools, electric scooters, electric bikes, and for companies selling rechargeable AA and AAA batteries (check out the NiZn cells at Ritz Camera), PowerGenix has opted not to create a brand name for their batteries (they don’t want to take on the big-spending bunny). Regarding automotive applications, PowerGenix plans to license their technology.
A battery analyzer can also trouble-shoot the cause of short runtimes. There are several reasons for this common deficiency. In some cases, the battery may not be properly formatted when first put in service, or the original charger does not provide a full charge. In other cases, the portable device draws more current than specified. A common problem is high internal battery resistance. Many analyzers can simulate the load signature of a digital device and verify the runtime according to the load requirements.
According to Squiller, the company’s batteries will be used in automotive applications (HEVs) in the foreseeable future, but probably not sooner than 2011 models. “We expect that HEVs will become a standard of sorts in the next few years,” Squiller said as he referenced the expansion of the “auto stop” feature on vehicles with standard internal combustion engines. “These vehicles represent the perfect application of Nickel Zinc battery technology, because they need bursts of power for short durations and this is something that our batteries do very well.”
Lithium-based batteries are sensitive to aging. If stored fully charged and at elevated temperatures, the battery deteriorates to a 50 percent performance level in about one year. Similar performance degradation can be seen on NiMH batteries when used under these conditions. Although still considered new, the user will likely blame the equipment rather than the battery for its poor performance. The analyzer can isolate such problems.
However, for what the automotive industry refers to as High Efficiency Vehicles (HEVs) — what we call conventional hybrids — a new battery technology is on the horizon that will make these vehicles less costly, less weighty, and even more green (in terms of battery pack recyclablility).
With a completion time of only ten seconds, the Cadex Ohmtest? provides the fasted measurement. Large numbers of HP Compaq Business Notebook NX6325 Battery can be examined if the packs are charged prior to the test. Measuring the internal battery resistance works reasonably well if reference readings are on hand. However, there are batteries that measure good internal resistance but do not perform well. This is especially common with nickel-based chemistries.
