OUTDO OT270 12 V 270 Ah GEL Deep-Cycle Battery
Exact reference · OT270-12(GEL)/CD
High-capacity 12 V GEL storage for a deliberately designed battery bank and inverter/charger.
- Rated capacity
- 270 Ah at 20 hours and 25°C
This rating is test-condition dependent and is not a usable-energy guarantee.
- Nominal arithmetic energy
- Approximately 3.24 kWh
Calculated from 12 V × 270 Ah; actual delivered energy depends on rate, voltage cutoff, temperature and condition.
- Higher-rate capacity
- 160 Ah at 1 hour · 195 Ah at 3 hours
Autonomy calculations must use the relevant discharge regime rather than the 20-hour headline.
- Charging boundary
- <75 A initial · 14.5–14.9 V cycle · 13.6–13.8 V float
The compatible charger and temperature compensation must be configured for the battery bank.
- Physical boundary
- 72.3 kg · T2 / M8
Handling, support, conductor termination and protective covers require project planning.
Do not select this battery from 270 Ah or “12 V” alone. Confirm required autonomy, discharge rate, bank voltage, matched battery quantity, charge profile, temperature compensation, conductors, protection, ventilation and handling.

01 · Product role
What this product does in the system.
The OT270-12(GEL)/CD is a sealed lead-acid GEL battery that stores DC energy. A separately selected inverter/charger converts power, controls charging and supplies AC loads. The battery has no BMS communications and cannot operate AC equipment by itself.
Relevant applications
- Off-grid solar battery banks
- Selected-load backup systems using a compatible inverter/charger
- DC energy storage where GEL charge settings and ventilation are engineered
Why ReneWave may shortlist it
- Provides 270 Ah at the stated 20-hour, 25°C test condition.
- Publishes separate one-hour and three-hour capacities for rate-aware design.
- Uses a sealed GEL deep-cycle architecture with documented charging windows.
Built-in capabilities
Four functions, read before the headline specifications.
Sealed GEL construction
Uses a GEL deep-cycle lead-acid architecture intended for controlled cyclic service.
Sealed construction does not remove ventilation, protection or handling requirements.
Requires a defined charge profile
The external charger must respect the documented current, cycle and float settings.
Temperature compensation and complete-bank behavior remain project-specific.
Publishes rate-dependent capacity
One-hour, three-hour and twenty-hour values support a more realistic autonomy review.
Headline amp-hours cannot be applied unchanged at every load.
System position
Storage behind a compatible inverter/charger.
The inverter/charger, PV conversion, protection and AC distribution are separate equipment. No direct PV-to-battery, battery-to-AC-load or grid-export path is represented.
PV supplies protected loads through the compatible inverter while the OUTDO battery bank remains idle.
Read the technical explanation
High-capacity 12 V GEL storage for a deliberately designed battery bank and inverter/charger.
The OT270-12(GEL)/CD stores DC energy. It does not contain an inverter, solar charger, AC charger, transfer switch or independent AC output. Its available capacity changes materially with discharge rate, temperature, cutoff voltage, age and charging history.
Source revision boundary
ReneWave publishes the values from the exact supplier-retained sheet for the requested grey-container reference. A separate manufacturer-authored mirror reports conflicting values and the current OUTDO catalog does not visibly list this 270 Ah model, so the delivered nameplate, container variant and charging record are reconfirmed in the written quotation.
