We believe everyone was aware about the recent incident happens to Samsung Note 7 whereby their latest phone was exploded due to faulty battery. Many cases reported worldwide and as an end user we need to take precaution to this matter. People tend to ignore and forget how IMPORTANT to take care of electrical devices especially when it connected to a battery. It seems to be very small yet ‘harmless’ piece of devise but do you aware that it can be very dangerous to people surrounding if you neglected on how to handle lithium battery properly.

➡How does a lithium ion battery work?

Like any other battery, there are three parts to a lithium ion battery: the anode, cathode and electrolyte. The anode and the cathode are electrical terminals called electrodes, and the electrolyte is the chemical in between them that conducts the electricity. While the cathode holds positively charged ions, the anode holds the negatively charged ones. Both anode and cathode are in the electrolyte but are separated by a physical barrier so they can’t touch. When the electrical devices is being used, charge is pushed from the positive cathode through the electrolyte and attracted to the anode before flowing out to the different components of the devices. Once you’re plugged in and charging, this process is reversed.

➡Why do they blow up?

Lithium ion batteries begin to degrade almost immediately after leaving the factory. For example, your two-year old phone won’t keep charge as well as a six-month old one. What’s more, they’re very sensitive to high temperatures. Secondly, when the (extremely volatile) electrolyte is inside a sealed battery case (like in a smartphone) pressure builds up and, on rare occasions, will actually puncture the casing. That’s when the electrolyte (which is more like a paste than a fluid) seeps out and comes into contact with the other components of the electrical devices. In these cases, it can ignite and set other parts of the device on fire.

➡How do you keep your lithium battery safely?

Any electrical devices that contains lithium battery including our Youha Breast pumps, you MUST take these precautions in order to keep it safely. Misusing the battery may cause the battery to get hot, explode, or ignite and cause serious injury. Be sure to follow the safety rules listed below:

⛔ Do not pumping while charge your breast pump
⛔ Do not carry or store the batteries together with necklaces, hairpins, or other metal objects.
⛔ Do not solder directly onto the battery / breast pump.
⛔ Do not place the battery / breast pump in fire or heat the battery.
⛔ Do not place the batteries / breast pump in microwave ovens, high-pressure containers, or on induction cookware. (just in case if some of you might curious to see how your breast pump baked :3 )
⛔ Do not install the battery backwards so that the polarity is reversed.
⛔ Do not penetrate the battery with nails, strike the battery with a hammer, step on the battery, or otherwise subject it to strong impacts or shocks.
⛔ Do not expose the battery to water or salt water, or allow the battery to get wet.
⛔ Do not disassemble or modify the battery. The battery contains safety and protection devices which, if damaged, may cause the battery to generate heat, explode or ignite.
⛔ Do not place the battery / breast pump on or near fires, stoves, or other high-temperature locations. Do not place the battery / breast pump in direct sunshine, or use or STORE THE BATTERY / BREAST PUMP INSIDE CARS in hot weather. Doing so may cause the battery to generate heat, explode, or ignite. Using the battery in this manner may also result in a loss of performance and a shortened life expectancy.
⛔ Do not insert the battery into equipment designed to be hermetically sealed. In some cases hydrogen or oxygen may be discharged from the cell which may result in rupture, fire or explosion.
⛔ Only use chargers that have specially been designed for use with lithium-ion batteries. Charger other than provided by Youha is not advisable. 
⛔ Do not attach the batteries to a power supply plug or directly to a car’s cigarette lighter.
⛔ Do not continue charging the battery / breast pump if it does not recharge within the specified charging time. Doing so may cause the battery to become hot, explode, or ignite. We recommend you to charge your breast pump for 8 hours / first time use and 2-3 hours after first time use. Please do not charge longer than this durations.
⛔ Immediately discontinue use of the battery if, while using, charging, or storing the battery, the battery emits an unusual smell, feels hot, changes color, changes shape, or appears abnormal in any other way. Contact your Authourised Reseller or Youha Malaysia if any of these problems are observed.
⛔ In the event that the battery leaks and the fluid gets into one’s eye, do not rub the eye. Rinse well with water and immediately seek medical care. If left untreated the battery fluid could cause damage to the eye.
⛔ When the battery is worn out, insulate the terminals with adhesive tape or similar materials before disposal.

We know this article might too long for you to read, but this is VERY IMPORTANT to ensure that our breast pump is safely used by our user. You can refer to our manual book provided in the breast pump set or contact your Authourised Reseller for more info. YOUHA ALWAYS CARE ABOUT YOU!
