Has your car or motor cycle battery gone ‘flat’ and refused to start during a crisis like a school run or a meeting? Arguably the answer is yes! And just to make the situation worse roadside assistance more often than not takes a long time to get to you! All of us go through this sometime or the other, and finally results in general mayhem and disorder.
Car and motor cycle batteries are in the family of rechargeable batteries called ‘Lead Acid Batteries’. A lead-acid battery (also know as an “accumulator”) is a secondary (rechargeable) electrochemical device that stores chemical energy and releases it as electrical energy upon demand. When a battery is connected to an external device, such as a motor, chemical energy is converted to electrical energy and direct current flows through the circuit. When the active material in the plates can no longer sustain a discharge current, a battery “dies”. It should be noted that car batteries are not meant for “deep discharge’ (i.e-being drained to a very low level and recharged)
Without regular charging a battery will eventually go flat, this is all the more common when the vehicle is not driven for extended periods of time. It is also a common mistake for people to leave certain systems running such as interior and exterior lights. Again, the effect is the same – the power contained within the battery discharges and the battery goes flat. This is a slow and complete discharge which will damage the capacity of the battery and its elecrtrolytes. There is another damage done by the battery being fully discharged, called Sulphation. Sulfation refers to the process whereby a lead-acid battery (such as a car battery) loses its ability to hold a charge after it is kept in a discharged state too long due to the crystallization of lead sulfate. Remember you must put back the energy you use immediately. If you don’t the battery sulfates and that affects performance and longevity. The alternator is a battery charger. It works well if the battery is not deeply discharged. The alternator tends to overcharge batteries that are very low and the overcharge can damage batteries.
Further, when charging a battery, using a cheap charger will do more harm than good if the charging isn’t done in a proper order to a standard. Let us look a bit more closely at the process of charging a battery. This contains four main steps,
1. Desulphation
Runs a complete charge cycle within a fraction of a second. The cycle repeats during the whole desulphation phase.
Every cycle recovers some lead sulphate into useful material.
2. Bulk
Charging where 80% of the energy is returned. The charger delivers a constant current until the battery voltage has reached the set level.
3. Absorption
Final part of the charge up to 100%. The battery voltage is kept constant at the set level, during which time the current drops gradually.
4. Pulse
Maintenance charging. The state of charge varies between 95% and 100%. A pulse is sent out to the battery if the voltage drops. This keeps the battery in trim when not in use. The charger can be connected for months at a time.
Thus to retain optimum life and operational capacity, batteries have to be charged in this way, especially when they have been deeply discharged. This type of charging is called regulated charging. Please note that only special SMART CHARGERS using computer technology can perform this special type of step charging techniques.
Thus it is important that you choose a good charger for your car battery! So wouldn’t it be great if you could carry a spare power source which can charge the flat batteries correctly and quickly without even removing the connections to the car? I know the answer is YES! And the great news is that-now you CAN! CTEK has developed a battery charger which can charge a car or motor cycle battery within 30 minutes and the charger itself can be recharged overnight using a domestic power supply. It uses the four step charging process discussed earlier and will enhance your battery life and maximize its operational capacity.

Dell Latitude Ppl Laptop Battery Protection Advises For Notebook Consumers
If customers are acquiring Laptop battery the vendors can say to them how many hours the Li-ion notebook battery may end, there are some causes that are lead to the defectiveness of the Notebook battery. Many of the laptop consumers don’t have idea of the technicalities included on obtaining the maximum Life out of their Dell latitude ppl Notebook power pack. Like other Notebook batteries, we should give care while those are unused. Don’t keep the laptop battery near liquids and in a clammy area as this can reduce Li-ion notebook battery power.
There is another simplified method to increasing the Notebook battery lifespan by de fragmenting disc & clean out unwanted files. This easy method can enable your laptop to boot up more quickly, which utilizes little energy. Adjust your notebook power settings with that it use the lowest amount of Power necessary to get your notebook functioning. bright display will consume much more battery power. change brightness when running the notebook pc on battery power.
Terminate entire insignificant programs if your notebook depending on Dell latitude ppl Li-ion battery as major power source. Don’t run virus scan when our notebook relaying over Battery pack, since the scan heavily enhance processor & hard disk utilization while working over laptop battery. Try to avoid to connecting to the internet until it is really necessary, when you are depending on your Dell latitude ppl Notebook battery as the only power resource. Perform anti virus scan when we are connected to major power resource. Don’t run virus scan when we are working on Notebook battery. This will save Notebook battery power.
When ever it’s feasible try to decrease the utilization of USB attachments like optical DVD or CD drivers or players, lead to use up a lot of energy to operate. Detach these optical devices and USB devices have the highest precedence to emptying the battery capacity. Unplug entire external peripheral such as an external mouse, fire wire, PC Cards, Wi-Fi tool box, External speakers, Pen Drives Bluetooth and even the connected i-Pod.
Hibernate and Suspend approaches are used for saving power of the Notebook Ba
1000
ttery although, generally notebooks takes much more Battery power in the SUSPEND form. We don’t know the reasons but “instant-on” obtain around 60 second’s more period of time to go out of Hibernation mode. This smaller quantity of period represents a major effect on the entire Note book Battery life duration. When in the hibernate mode in and out are really convenient and efficient than a normal start & shutdown procedure. In hibernate mode the system shutdown activity gives a possibility to hold contemporary work instantly with power-off and in start up activity this will go on with in a short period totally, Hence this method saves power. How ever stand by mode reduces the energy expenditure of your laptop through not supplying the energy to the hardware components that you are not using. Thus by using Hibernate method you can saves the Notebook Power pack energy. We can put the shortcut icon for hibernate as a replacement of the lengthy activity (once carrying out the manual task in Control
panel next onwards make use of the created shortcut icon by Pushing “Windows button” followed by U pursue by H). If we have some work at outside for longer time, in such state use the hibernate method instead of to suspend mode.
Every Laptop consumer need to make the Dell latitude ppl Notebook Battery pack last as long as possible. However each Notebook battery has the Limited life span. Hence if we can go through the above good Li-ion rechargeable battery tips that may help to prolong the notebook battery life period.
