What is a Jump Starter?
Lithium battery is famous for great performance. And lithium jump starter belong to lithium battery. Thus lithium jump starters also have higher energy density, smaller size, lighter weight. So lithium jump starter is easy to carry. If you are a stranger in lithium battery industrial, the following are detailed explanation about good performance of lithium battery.
(1) More Available Capacity
Unlike lead-acid batteries that rarely discharge more than 50% of their power, lithium batteries can regularly discharge 80% or more of their rated capacity. For example, for a 200Ah lead-acid battery, you can only get 90-100Ah of power, but with lithium batteries you can use more than 180Ah. It is about twice as much as an equivalent rated lithium battery pack. Thus we always regard lithium batteries as high efficient power supplies.
(2) Longer Cycle Life
The cycle life of batteries directly decide how long your battery can be used. Lithium batteries can be charged 2000 times and remain 80% of the original capacity, while the best deep-cycle AGM batteries usually only cycle 500-1000 times. Although the price of lithium batteries is about three times that of AGM batteries, but the longer life makes lithium batteries worth the money.
(3) High Output Current
High discharge rate can provide large current. Lithium batteries can be powered down at high current rates without losing Ah capacity, while lead-acid can be reduced to 40% of the Ah rating at high discharge rates which means that lithium battery packs are much better when powering high-current loads such as microwave ovens or air conditioners.
(4) Fast Charging
The lithium battery can be quickly charged to full capacity because it can reach 0. 5C while the lead-acid is only 0. 2C. And the absorption mode is in the final stage of charging, not the typical 80% of lead-acid. This greatly reduces the charging time.
(5) Low Self Discharge
The jump starter will self-discharge after being produced. After a long period of unused self-discharge, the battery voltage will be too low to start the car. Compared with lead-acid batteries, the speed of dropping capacity is too slow. For lithium batteries, per month, the self discharge is about 2-5%, while lead-acid batteries of that is about 10-15%.(6) High Weight Energy DensityThe energy density of current lithium batteries is generally 200~260wh/g, and lead acid is generally 50~70wh/g. Then the weight energy density of lithium batteries is 3~5 times that of lead acid, which means that under the same capacity, lead Acid batteries are 3 to 5 times that of lithium batteries, so lithium batteries have an absolute advantage in lightening energy storage devices.
(6)High Volume Energy Density
The volume capacity density of lithium batteries is usually about 1.5 times that of lead-acid batteries, so with the same capacity, the volume of lithium batteries is about 30% smaller than that of lead-acid batteries.
According above advantages of lithium batteries. Do you still have doubts on which kind of battery is better? Of course not, we can easily gain the answer that lithium jump starters are much better than lead-acid batteries
How to Choose a Right Lithium Jump Starter?
*Safety
These lithium batteries contain electricity which is dangerous when not handled correctly. It’s a good thing to keep jump starters away from disasters like fire and explosion if jump starters have following safety functions.
Short Circuit Protection – prevents high current from passing from positive to negative clamps when accidentally touched together
Overcharge Protection – when the jump starter’s batteries are full, this will “float” charge the unit and keep excess voltage from being applied to the cells
Over-current Protection – prevents damage to the jump starter by keeping it from supplying more current than it’s peak limit
Overload Protection – keeps the jump pack from receiving more current than the manufacturer’s specifications when being charged
Over-voltage Protection – keeps the jump pack from receiving more voltage than manufacturer’s specifications when being charged
Most jump starters have the above protections built in but always check the listed safety features to make sure. There’s one optional safety feature that’s a must, though. Reverse polarity protection keeps you from damaging your battery when you connect the cable clamps to the battery terminals. Red is positive and black is negative. The positive cable attaches to the positive terminal while the negative cable goes on the negative terminal. Don’t be confused about them.
*The Power of Portable Jump Starters
Jump starter power is expressed either as cold cranking ampsor peak amps. Measuring CCA tells you what to expect from your battery in the worst starting conditions imaginable. There are two main factors to consider when deciding what power level is right for you.
Your Engine Size
A compact or small sedan battery can be jumped with as little as 150 CCA. Full-size trucks and SUV’s need around 450 CCA. Engine size is important but age is part of the equation, as well.
Your Vehicle Age
Assuming similar sized vehicles, the older the vehicle the more amps are needed to jump it. For example, a 20-year-old, 8 cylinder engine pickup needs more amps to start than a brand new one. This is due to improvements in engine design and newer starter motors. As a general rule, 400-500 CCA should start most any passenger vehicle on the road. Remember, your car isn’t the only one you may be jump starting. Choose a portable jump starter that allows you to help a fellow motorist in need too.
*Durability: A lithium-ion jump-starter should be able to endure a lot of use and keep working for a long period.
*Ease of Use: It must be easy to use and dependable.
Tips to Prolong Lithium Jump Starter Life
Following these simple steps can greatly extend the life of your jump starter and also help to ensure that your jump starter is ready for service each time you need it.
Tip 1: Don’t Store Powerless Batteries.
We suggest that you recharge your jump starter to keep the battery power above 80% to prolong your battery lifespan and to prevent emergency issues. It is strictly forbidden for your lithium jump starter to be in a state of power loss when it is stored. Storing the battery in a state of power loss, it is easy for your jump starter to self-hibernate and protect from low power, resulting in insufficient charging and a decrease in battery capacity. The longer the idle time in the power-loss state, the heavier your jump starter damage. Therefore, when your jump starter is idle or not in use, it should be recharged once one or two months to better maintain the healthy state of your jump starter.
Tip 2: Do Regular Inspection
During use, if the using time of your jump starter suddenly drops in a short period of time, it may be that the battery capacity is insufficient or it is not really fully charged. At this time, you should go to a professional repair agency in time to inspect and repair your jump starter and car. This can relatively extend the life of jump starter and save money to the greatest extent.
Tip 3: Don’t Over Charge
Using proper charger to charge your lithium jump starter and controlling charging time according to manufacturers’ instruction and the you battery using frequncy are good ways to avoid over charging. Under normal circumstances, the jump starter is charged at night, and the average charging time is about 8 hours. Over charging will lead jump starters to bulge and heat up which can shorten battery life. Therefore, it is best to charge your jump starter once when the machine prompts that it needs electricity, and make the necessary charging according to the actual situation to avoid harmful charging.
Tip 4: Don’t Explore Jump Starter to Sunlight for a Long Time
Batteries are strictly prohibited from being exposed to sunlight. An environment with too high temperature will increase the internal pressure of the battery and force the battery pressure limiting valve to open automatically. The direct consequence is to increase the probability of jump starter fire or explosion.
Tip 5: Avoid the Plug Heating Up When Charging
Phenomena such as loosening of the charger output plug and oxidation of the contact surface will cause the charging plug to heat up. Too long heating time will cause the charging plug to short circuit, which directly damages the charger and causes unnecessary losses. Therefore, when the above situation is found, the oxide should be removed or the connector should be replaced in time.
How to Jump Start your Vehicle?
Step 1:Connect the jumper cable clamps to the battery terminals (first Red to Positive, then Black to Negative )
Step 2:Connect the jumper cable to the jump starter
Step 3:Wait for the green LED on the jumper cable to light up and then start your vehicle
Step 4:Disconnect the jumper cable from the jump starter and then from the battery in reverse order
Note that if the vehicle does not start after several attempts, your jump starter may stop working (or go into “recovery mode”) to prevent the battery from overheating. This may happen if the vehicle battery is too far drained to be able to be jump started.
