What is ME Battery and what is it for?
The ME Battery collection groups sealed lead-acid batteries of 12 V in AGM and GEL technologies, ideal for off-grid solar systems, backup power (UPS), caravans, boats, and telecom. These are maintenance-free VRLA batteries, with a safety valve, low self-discharge, and good resistance to vibrations, designed for simple and safe integration.
Advantages and limitations
- Safety and zero maintenance: sealed VRLA technology (no refilling or gases under normal use).
- Wide range: typical capacities from 8–220 Ah to adapt bank size and autonomy.
- AGM: lower internal resistance, good current delivery, and fast recharge.
- GEL: better performance in deep cycle and high temperatures.
- Limitations: lower energy density and cycle life than lithium batteries; require basic ventilation and suitable charging curves.
Recommended applications
- Off-grid solar: homes, shelters, irrigation cabins, or telecom.
- Marine and caravanning: service batteries for 12 V loads (lights, pumps, electronics).
- Backup: UPS, emergency lighting, and small critical loads.
- Pumping systems and pressurization with suitable converters or inverters.
How to choose your ME Battery
- Technology: AGM for current peaks and frequent recharges; GEL for deep cycles and high ambient temperatures.
- Capacity (Ah): size according to daily consumption (Wh), 12 V voltage, and target DoD (e.g., 50–70 %).
- Configuration: banks at 12/24/48 V by connecting in series and/or parallel; use balanced cables and protections.
- Charger/regulator: IUoU curve compatible with AGM/GEL, thermal compensation, and voltage limits by technology.
- Installation: place in a ventilated area, avoid repeated deep discharges, and maintain tightening torques.
Indicative specifications
| Nominal voltage | 12 V (configurable in 24/48 V banks) |
| Technologies | Sealed AGM / GEL VRLA |
| Typical capacities | 8–220 Ah |
| Recommended use | Medium/deep cycle, 12 V services, backup |
| Maintenance | Maintenance-free (sealed) |
| Charging compatibility | PWM/MPPT regulators and 12 V chargers with AGM or GEL profile |
Best practices
- Limit depth of discharge to extend life (e.g., 50 % DoD in solar use).
- Use protections and battery monitor to control voltages and ampere-hours.
- Equalization: do not apply to GEL; for AGM only if allowed by the manufacturer and with controlled voltages.
- Temperature: every 10 °C above 25 °C reduces lifespan; ensure ventilation.
Comparisons and quick selection
- AGM 12 V 100–150 Ah: cost/performance balance for small off-grid homes.
- GEL 12 V 150–220 Ah: deeper cycles and better thermal stability in warm climates.
- Is weight/volume critical or do you need more than 3000 cycles? Consider lithium batteries.
