Renogy 12V 100Ah Deep Cycle AGM Battery

Overview

This sealed AGM deep-cycle battery delivers reliable, low-maintenance power for RVs, solar systems, boats, and backup setups. With over 230,000 units sold worldwide, it’s designed to work across a wide temperature range, tolerate high starting currents, and be connected in series or parallel for larger systems.

Benefits

• Spend less time on maintenance — the sealed AGM design eliminates regular electrolyte checks and internal troubleshooting.
• Use power reliably in cold or hot conditions — the electrolyte formula maintains discharge performance from -4°F to 140°F (-20°C to 60°C).
• Start heavy loads without worry — a high short-term discharge capability handles appliance start-up surges.
• Scale your system easily — connect batteries in series for higher voltage or in parallel (up to 4) for more capacity.
• Protect your investment — pairing the battery with a monitor or balancer helps avoid over-discharge and extends service life.

Features

• 12V deep-cycle AGM (Absorbent Glass Mat) construction — maintenance-free, spill-proof design.
• High chemical stability compared with some lithium chemistries for improved safety in typical use.
• Wide discharge temperature range: -4°F to 140°F (-20°C to 60°C).
• Max short-term discharge: 1100A for 5 seconds (suitable for starting appliances).
• Series and parallel support — series connections (no limit), parallel up to 4 batteries.
• Includes terminal bolts (M8 x 1.25 x 15 mm, two pieces).
• Compatible with battery monitoring (Renogy 500A Monitor recommended) to track state of charge and prevent over-discharge.
• Recommended battery type setting for charge controllers: SLD.
