DEFORD unveils their NA1270 Pro sodium marine battery in July 2024.
After more than one year of testing, DEFORD New Power Co., Ltd finally released their NA1270 Pro sodium-ion marine battery in July 2024. NA1270 Pro is a 12V marine starting + deep cycle dual-purpose battery based on sodium-ion battery technology. The launch of NA1270 Pro battery will fundamentally change the landscape of the marine battery market in the next few years.
Lead acid battery has been dominated the marine battery market for more than one century. Lithium-ion battery is not good at cold-starting the engine and therefore cannot meet the requirements of starting batteries. Sodium-ion batery has excellent low-temperature discharge performance and can still meet the 10C discharge requirements even at -28 degrees Celsius. In terms of CCA performance, sodium-ion battery is even more advantageous than lead acid battery.
Lead acid battery should strictly avoid over-discharge to prevent irreversible loss on capacity. Whilst Sodium-ion battery is not afraid of over-discharge and can be discharged to 0V, there will be no loss of capacity after recharging. Lead-acid battery usually need to be charged every 3 months to keep the performance, while sodium-ion battery can extend the chargingtime to 12 months.
The abundance of sodium in the earth's crust is 2.3%, ranking sixth among all elements, significantly higher than 0.0017% of lithium. Sodium is widely found on land and in the ocean in the form of salt and is easy to obtain. Compared with lead-acid battery, sodium-ion battery is eco-friendly. Sodium-ion battery does not contain any heavy metals and are 100% recyclable.
NA1270 Pro battery will promote a major shift in marine battery from lead-acid battery to sodium-ion battery. The performance parameters of NA1270 Pro battery can be obtained from the following table.
