Recently, a tragedy has attracted attention: in order to extend the battery life of an electric vehicle, a man purchased non-standard lithium batteries through merchants and increased the price for a high-capacity model. The battery burst into flames during cycling, and the wife in the back seat suffered severe burns that left her permanently disabled. The fire service determined that the fault was the non-standard combination battery that changed its capacity and dismantled its protection.
Many owners feel that it is more cost-effective to put together and add batteries, but they must be sternly reminded: this is not "cost-effective" choice, but a gamble on life's luck! While non-standard batteries may seem cheap and affordable, they are actually "mobile bombs" that can detonate at any time.

DIY batteries. It's not really feasible!



Many people think that it is easy to put together and add batteries, and some merchants will promote the relevant service and claim that it is "safe," but this is not the case. The batteries, lines and chargers of regular electric vehicles are all supported by the original factory and have been strictly tested for safety, so as to avoid problems such as overload and short circuit. In contrast, non-standard batteries disregard safety standards, arbitrarily pair battery cells, protection boards, even change capacity, dismantle protection, and mixed battery cells. Once used, the risk of igniting and catching fire increases significantly, as is the tragedy in the above-mentioned cases.

4 Fatal Dangers of Non-standard Lithium Batteries
1. Heat gets out of control frequently, and bursts with no warning.
The most prominent danger of non-standard lithium batteries is the tendency to lose heat control. Regular lithium batteries are separated by industrial grade capacitance and the core parameters are consistent; In contrast, non-standard lithium batteries mostly use cheap, inferior or used cells, often change capacity, disassemble protection, and have no professional testing, and the unity of the cells is extremely poor.
In this case, when the battery is charged and discharged, it is easy to see some of the cells overcharge and discharge, and once the pressure difference exceeds the standard, it will quickly generate a hot drum, which will trigger heat loss, and may explode within seconds. What's even more frightening is that bursting often does not have obvious warning, can occur while riding, charging, and parking, and is extremely hidden and harmful.
2. Line alignment is imbalanced, and short circuit risk is everywhere
Self-assembled batteries and adding batteries mostly alter the original lines, and most operators lack professional electrical expertise and cannot ensure that the lines, batteries, and chargers are suitable. The inconsistent thickness of the line will cause heat aging, and the improper wiring will easily lead to false coupling, short circuit, and instantly cause fire.
Some owners add batteries in pursuit of longevity, forming "dual battery systems" or even mixing different kinds of cells, further exacerbating the voltage and current imbalance, creating the risk of overload, and easily causing self-ignition.
3. Without security certification, you can only think you're unlucky when something goes wrong.
Formal lithium batteries are subject to national standards and international safety tests, have quality assurance and insurance, and can be held liable in accordance with the law if a problem occurs. Moreover, non-standard lithium batteries are "three without" products, with no safety certification, no quality assurance, and no complete after-sales service.
Once a safety accident occurs, the seller and the assembler will repeatedly assume responsibility, and all losses and liabilities are borne by the owner, who will also bear physical and mental pain and huge costs.
4. Suspected of violations of the law and the risk of related penalties
DIYing and adding batteries to an electric car is not only dangerous, but also suspected of breaking the law. According to relevant regulations, electric vehicle batteries need to meet national security standards, and private modification is an offence.
Drivers of modified electric vehicles on the road may be detained and fined; Merchants or individuals who provide illegal assembly and modification services will be punished with a heavy fine, cause an accident, and be held criminally responsible.

Longevity tip: Safety is far more important than longevity for daily commutes and family errands. Lead-acid batteries are the best choice for safety, practicality and cost-effectiveness, compared to lithium batteries, and their safety advantages are especially prominent, which is more suitable for the daily travel needs of ordinary drivers.
Long New Batteries, which focuses on the field of lead-acid batteries, also ensures the highest level of safety, relying on mature processes and rigorous testing, so that each battery can withstand the test, which strengthens the safety line for travel.



01
The risk of heat loss is extremely low and the safety is higher
Lead-acid batteries have a mature and stable chemical system, and after strict production testing, even if they are slightly crushed, shaken or abnormally charged and discharged, they are not prone to heating, puffing, and bursting.
02
Structure stable, not prone to fluid leakage short circuit
The internal structure of the lead-acid battery is strict, the enclosure is strongly protective, and the electrolyte leakage is not easy during normal use, and it can also effectively avoid the safety problems caused by the internal short circuit.
03
A loving warranty service
Long New Battery has launched a policy of "12 months for a new" and "15 months for another brand new" to let users buy with peace of mind and use with peace of heart.
