Product Description

The Renogy Deep Cycle AGM Battery 12V 200Ah 2-Pack delivers a 400Ah, 12V bank from two sealed absorbed glass mat (AGM) batteries. AGM is a proven, no-fuss chemistry: sealed and low-maintenance per Renogy, no watering, and discharge rated down to -4°F without heaters or electronics. Two large 200Ah monoblocks mean fewer interconnects and fewer cable runs than four smaller batteries of the same total capacity.

Who This Is For

This 2-pack fits RV and fifth-wheel house banks, solar storage for cabins and outbuildings, and backup systems that float most of the year and cycle during outages. It is a straightforward drop-in for existing 12V lead-acid systems — your existing AGM-compatible converter, charge controller, or alternator charging keeps working. Prefer smaller 63.9 lb cases over 127.9 lb monoblocks at the same total capacity? Consider the Renogy 12V 100Ah AGM 4-pack instead.

Key Features

400Ah of combined capacity from two 12V 200Ah AGM batteries (rated at the 20-hour rate to 10.5V, per Renogy)
Sealed, low-maintenance design, per Renogy — no watering or electrolyte checks
500 cycles at 50% depth of discharge, per Renogy
Self-discharge below 3% per month at 77°F, per Renogy
2,000A maximum discharge current (5 seconds) per battery for surge and inverter start-up loads
Discharge rated from -4°F to 140°F
Supports series connection and parallel connection up to 4 batteries, per Renogy

Why Renogy

Renogy has supplied batteries and solar equipment to the US off-grid market for over a decade, and publishes the datasheets, manuals, and warranty terms behind its ratings. These AGM batteries carry a 2-year prorated material and workmanship warranty, and OffGrid Horizon is an authorized Renogy dealer, so your coverage is valid from day one.

AGM or Lithium? An Honest Comparison

Neither chemistry wins outright — it depends on the job.

Where AGM makes sense: lower upfront cost; discharge rated to -4°F with no battery management electronics or heating required; comfortable on float duty for standby and backup systems; fully compatible with the lead-acid charging equipment already in most RVs and boats.

Where lithium makes sense: Renogy rates its CORE LiFePO4 batteries at 5,000 cycles at 80% depth of discharge versus 500 cycles at 50% for these AGMs, and a CORE 300Ah battery weighs 60.63 lb in a similar case size to this 127.9 lb AGM. That means more usable capacity per pound and per cycle — at a higher upfront cost, and with heating required to charge below freezing.

For frequent deep cycling or weight-limited builds, lithium earns its price. For standby, seasonal, and budget-driven systems, AGM remains a sensible, proven choice.

Warranty & Support

Renogy covers these batteries with a 2-year prorated material and workmanship warranty (see Renogy's warranty terms). OffGrid Horizon is a family-owned authorized Renogy dealer — call (302) 496-3554 for sizing help, troubleshooting, or warranty support.

Shipping

At about 256 lb of batteries, this 2-pack ships within the US by LTL freight on a pallet. The carrier will typically call ahead to schedule a curbside delivery. Before signing the delivery receipt, count the packages and inspect for damage — note anything on the receipt or refuse the damaged piece to keep your claim options intact.

Frequently Asked Questions

How much of the 400Ah is usable?

Renogy rates cycle life at 50% depth of discharge, so plan around roughly 200Ah usable to preserve battery life. Deeper discharges are possible but shorten cycle life.

Do these need venting or maintenance?

Renogy describes them as sealed and low-maintenance — no watering or electrolyte service. Keep them upright, do not place them upside down, and follow the manual's installation guidance.

Can I expand this bank later?

Yes — Renogy supports parallel connection up to 4 batteries, so you can add up to two more 200Ah units, and series connection is supported for 24V or 48V arrangements.

What charge settings do these want?

An AGM profile: 14.4V to 14.8V for cycle use and 13.6V to 13.8V float, per Renogy, with charge current up to 60A per battery (120A across the pair).

How should I store them in the off-season?

Store fully charged in a dry, cool place and recharge about every three months, per Renogy's care guidance.

How heavy is each battery?

127.9 lb, in a 20.6 x 9.4 x 8.8 in case. Plan a two-person lift and a battery tray or compartment floor rated for the weight.
