Product range
Models, ratings and practical differences
NPL Series is catalogue-described as a high-tin, eight-year design-life AGM family and mirrors a wide set of 6V and 12V capacities. GM Series uses a thick-plate 2V design from 50Ah to 3000Ah with a 10-year catalogue design-life statement. They are not interchangeable: NPL suits conventional multi-battery arrangements, while GM cells support larger stationary strings and require rack, inter-cell connection and installation planning.

How to choose
Start with the load, charger and available space.
Send the information you already have. We can narrow the model list and point out what still needs to be checked.
Choose 12V blocks or 2V cells
The system voltage, bank capacity, rack, maintenance access and replacement strategy drive the architecture.
Use rate-specific capacity
Select from the capacity at the expected discharge duration and end voltage, then include aging and temperature margin.
Typical applications
Where buyers use this battery family
Tell us about the equipment and duty cycle. We will help check whether this series is a practical fit.
Solar and renewable storage
Size from daily load, autonomy and recovery energy—not only array capacity.
Mobility and cyclic equipment
Confirm peak current, vibration, charging opportunity and physical restraint.
Stationary cycling
Plan racks, inter-cell links, protection, ventilation and string monitoring for larger 2V banks.

Product FAQ
Questions buyers ask before ordering
We will confirm current availability, documents and commercial terms for the exact model you select.
What is the main difference between NPL and GM?+
NPL is a 6V/12V AGM block family; GM is a 2V thick-plate cell family for larger stationary banks.
Why is 10-hour capacity different from 1-hour capacity?+
Lead-acid available capacity falls as discharge rate increases. Select using the runtime column closest to the application.
Does deep-cycle mean unlimited cycling?+
No. Cycle life depends strongly on DOD, temperature, charge recovery and time spent partially charged.
Can this replace an AGM standby battery?+
Possibly, but charger settings, space, terminals and duty must be reviewed. The key benefit is alignment with repeated cycling.
What information is needed for sizing?+
Provide load, runtime, cycles per day, DOD, recharge source, temperature, voltage and available installation space.
