18650 Battery Jump Starter-Methods and Buying

If you are thinking of saving money, you can do this with the help of lithium-ion batteries having all the shapes and sizes. The lithium batteries develop memory or have low self-discharge. Here you will find the techniques to extract and salvage lithium-ion batteries.

How do you jump a 18650 battery?

It is important to know about the battery before jumpstarting the battery. The rechargeable battery 18650 means the battery is 18 mm in diameter and 65 mm long. These contain single cells or have multiple cells provision also. Multiple cells have a series or parallel or a mix of both.

The small batteries can have two small cells inside connected in series or series/parallel. The advantage of connecting in series is, it increases the voltage, and parallel connection increases the capacity of the pack.

Safety Equipment

• Safety Goggles

• Electrical Gloves
  

Extracting cells is straightforward. Some basic tools are required, and these are:

• Flat blade Screwdrivers- There is a requirement of various sizes, but it is good to have a size from 3mm to 5 mm. Avoid using thick blades that take a lot of space and get difficult to be kept in small spaces.

• Spudger -  Metal or strong plastic one for separating cases.
  

• Side Cutters/Flash Cutters – It helps to cut the battery or thick tabs and wires. The flash cutters would be a better option to split the cells.
  

• Utility Knife – If you have this one, it would be better than a spudger.
  

• Multimeter – It is used for measuring the voltage.
  

• Gloves – Gloves are used for this task as it helps to protect from the sharp edges of the equipment.
  

How do you buy a good 18650 battery jump starter?

• Selecting the right 18650 cells for the battery pack

There are many types of 18650 cells in the market in the price range of $1 to $10, the batteries of 18650  have uses in branded companies such as Panasonic, Samsung, Sanyo, and LG. These cells have excellent performance and quality control.

• Ensuring Safety by selecting right battery Strips

Some safety steps should be followed before picking the battery strips. Single 18650 holds a lot of energy. If you have near about six batteries, then there is a sufficient amount of potential stored energy.

The safety aspect comes if the batteries are short-circuited, overcharged, or undercharged. Mostly lithium batteries get heats up and swell up and tend to explode.

The optimal way to avoid this is to handle and charge them correctly. The lithium-ion batteries have some kind of protection circuitry built into them to protect the cell from getting overcharged and short-circuited.

Multi- cells have an extra feature called battery management system that monitors the current and voltage across each cell. It makes sure that each cell is loaded with the same current and voltage.

The appropriate charger should be used for every device as instructed. Otherwise, it can cause lithium-ion cells to overcharge and result in a fire.

• Deconstruction

It depends upon the battery, and mostly the basic design is the same. There will be no difference in construction between the generic and genuine OEM.

Many times the case is glued or welded, but other times it is held together with the tabs. You will easily find the method of the manufacturer. OEM batteries are fixed, and cheaper ones are clipped.

You can start from the corners with the utility knife first. Inset Knife through the edge, the main aspect is to have a small gap. After that, you have to use a screwdriver to open the gap by twisting it. If you have successfully opened it, then you can take the help of a bigger screwdriver and repeat the process.

If you are getting large creases, then you can twist it. Otherwise, you need to repeat the first step if you get stuck.

• You're' in!

After some time, you should be able to separate the case. Inside the case, you will have some basic features such as a battery management board that consists of protection and balance circuits.

• Salvage Operation

In Salvage operation, you can check the battery age and measure the voltage or check the date codes on the circuit board inside. If your battery read under 2 volts, they are assumed to be dead.

You can only salvage the very low voltage cells, but you need a special charger to revive the dead batteries or use some special techniques to bring them in a working state.

• Revival

If you have a balance charger designed especially for charging LiPo batteries, then you have a chance that you can revive your lithium-ion cells too. Digital multi-charger can also be useful.

If you have a Zanflare charger, then the charger will do the work quickly. Let it get fully charged, and then take them out from the charger and keep the batteries as it is. Don't use them. If they are significantly self discharged then toss them out. But if they are holding the charge, then you can revive them.

If you don't have a Zanflare charger, you can use a LiPo charger. These chargers are the safest chargers and cannot charge a cell under 2.6 or 2.5 Volt range. You have to take care if you are charging NiMH lithium-ion. You have to keep the charger in NiMH mode and manually select the charge current and voltage. Monitor the voltage until it gets above 2.8 after that remove the charging.
