Automotive, Marine, Solar and Industrial Batteries

nsb agm27mAutomotive, marine, solar and industrial batteries are commonly lead-acid and lithium batteries ranging from just few Ah to 500 or even more Ah.

These batteries are optimized for various purposes and when looking for an equivalent battery (or batteries), be sure to check size battery type, its chemistry, dimensions, capacity, max. drain current, max. pulse current, charging current and/or voltage, shelf life, self-discharge rate etc.

While lead-acid batteries (flooded, gel cell, AGM) are norm for industrial batteries, lithium batteries are offering many improvements, especially regarding weight and number of charging/discharging cycles.

With the improvements in electronics and chemistry, lithium batteries with Battery Management System (BMS) are more and more often used as drop-in replacement even for high-end AGM batteries.

But, price, reliability and simplicity of the lead-acid (especially AGM) batteries warranty their use long in the future.


And here are our reviews and recommendations of the most popular automotive, marine, solar and industrial batteries:
