Mercury Inverter Battery 65Ah (12V)
Dependable small‑footprint backup for homes & small offices in Nigeria—ideal for lights, fans, Wi‑Fi, TVs, POS and essential electronics.
Description
This 12 V 65 Ah deep‑cycle battery packs roughly 780 Wh of energy—enough to power your lights, fan, Wi‑Fi router, TV and POS machine for up to about three hours on a single unit (based on a 120 W load). Its compact footprint makes it easy to fit into small homes and offices. Rated for over 600 cycles at 50 %% depth of discharge, it’s built to withstand frequent NEPA outages and will keep performing for years when charged correctly. Use it as a standalone battery for small inverters or combine multiple units for longer runtime or larger power systems.
Why Nigerian buyers choose the Mercury 65Ah
- Compact deep‑cycle design: Standard 12 V/65 Ah AGM battery fits easily into most battery racks and cabinets, saving space while delivering dependable power.
- Dependable runtime: Provides about 780 Wh of usable energy—enough to run lights, fans, Wi‑Fi and TV for roughly three hours at 120 W. Pair two or more batteries to double or triple your backup time.
- Long service life: Rated for 600+ cycles at 50 %% depth of discharge, translating to 3–5 years of everyday use when properly charged and maintained.
- Safe & maintenance‑free: Spill‑proof sealed AGM design with built‑in safety valves protects against leakage and over‑pressure; no water top‑ups required and low gas emission during charging.
- Installation & support: Compatible with all major 12 V inverters and charge controllers. We offer Lagos same‑day delivery, professional installation, and a manufacturer‑backed warranty with local support.

Who this is perfect for
This battery suits mid‑career professionals, entrepreneurs and small business owners who need a clean, quiet backup solution for their essential devices without the noise and fuel costs of generators.

FAQs about Mercury 65Ah Inverter Battery
Is 65 Ah enough for a 1.0 kVA inverter?
For light loads, yes. For heavier or longer backup, use a larger battery or a second 65 Ah in parallel (or move to a 24 V system with matched batteries). Always size batteries to your load and target runtime.
Lead‑acid or lithium—what should I choose?
65 Ah sealed lead‑acid batteries are affordable and reliable for essentials. Lithium (e.g., 24 V/48 V packs) costs more but provides deeper cycles, faster charging and longer life if your budget allows.
Can I charge it with solar?
Yes. Match your charge controller to 12 V AGM settings and size your PV array so daily solar production comfortably replaces the energy you use during outages.
How do I make it last longer?
Avoid deep discharge, set the correct charge voltage/current, keep the battery ventilated and cool and prevent chronic under‑charging.
Buying Guide: Is 65 Ah right for me?
- Your goal: Keep home/office essentials running during outages with a compact, quiet setup.
- Your pattern: Frequent short outages in Lagos and similar cities; occasional longer ones.
- Best match: One 65 Ah for small loads; two 65 Ah if you want more runtime; consider 100–220 Ah for fridges/air conditioners or longer autonomy.
