Description
Advanced performance for demanding deep cycle applications. The 12V 100Ah Lead Carbon Battery (Group 27) is designed for superior cycle life, faster charging, and improved performance in partial state of charge conditions. Ideal for solar, off-grid, RV, and marine systems, it delivers reliable power with enhanced durability compared to traditional AGM and flooded batteries.
This Group 27 deep cycle battery is a popular size for RVs, marine house banks, and backup power systems where consistent performance and long service life are critical.
Unlike standard AGM batteries, lead carbon technology reduces sulfation and extends battery life, especially in applications where batteries are not fully recharged daily.

FAQs
What is a lead carbon battery?
A lead carbon battery is an advanced lead-acid battery that uses carbon additives in the negative plate. This improves charge acceptance, reduces sulfation, and extends cycle life compared to traditional AGM and flooded batteries.
Is lead carbon better than AGM?
In many applications, yes. Lead carbon batteries perform better in partial state of charge conditions, recharge faster, and typically last longer than AGM batteries, especially in solar and off-grid systems.
Is this battery suitable for solar systems?
Yes. Lead carbon batteries are ideal for solar energy storage, especially in systems where batteries may not fully recharge every day.
Can I replace an AGM or flooded Group 27 battery with lead carbon?
Yes, as long as voltage, size, and terminal type match. However, you should confirm your charger or solar controller settings for optimal performance.
Does this battery require maintenance?
No. This is a sealed maintenance-free battery and does not require watering.
Is this battery available for shipping?
Due to its size and weight, this battery is available for in-store purchase only. Contact us to confirm availability or inquire about local delivery options.
