Unocho 12V 750mA automatic battery charger and maintainer charges and then holds 12V lead‑acid batteries at a safe float level until you need them.

Compact and user-friendly, this Unocho battery charger is built to revive and preserve 12V lead-acid batteries used in motorcycles, cars, ATVs, boats and lawn equipment. It combines a multi-stage charging routine with built-in safety features and a detachable SAE lead so you can switch between ring terminals or alligator clips. The unit is designed for small to medium capacity batteries and prioritizes maintenance charging after the battery reaches full capacity.

How does the Unocho charger manage the charging process?

The charger runs a controlled three-stage sequence that brings a depleted battery to full charge, then drops to a maintenance mode to avoid overcharging. This staged approach balances speed and battery longevity by reducing current as voltage rises and then floating.

  • Constant-current stage to replenish depleted cells.
  • Constant-voltage stage to finish charging safely.
  • Float/maintenance mode to keep batteries topped without damage.

Which battery types and capacities are supported?

Designed specifically for 12V lead‑acid chemistry, the Unocho charger supports common formats such as AGM, GEL, SLA, VRLA and flooded (wet) cells. It’s optimized for batteries in the 3–18Ah charging window and can maintain batteries up to 36Ah in long‑term storage.

  • Compatible: 12V AGM, GEL, SLA, VRLA, WET batteries.
  • Charging range: approx. 3–18Ah effective charging capacity.
  • Maintenance range: up to 36Ah for seasonal preservation.
  • Not suitable for 6V, 24V, or lithium battery chemistries.

Is the Unocho charger safe and how does it indicate problems?

The charger has several protective circuits to reduce risks from incorrect hookup, shorts or overheating. A simple LED array communicates status and flags faults so you can act quickly if an issue appears.

  • Reverse polarity protection prevents damage from swapped connections.
  • Short‑circuit, overcurrent and overvoltage safeguards included.
  • LED status: yellow for charging, green for ready/float, red for reverse polarity, no light for short condition.
  • Thermal and overload protection for extended use and hot environments.

How do I connect this charger to different vehicles or batteries?

The Unocho unit includes an SAE quick‑disconnect lead and two connector options so you can adapt to multiple setups without rewiring. Use the ring terminals for permanent or semi-permanent installs and alligator clips for temporary or bench charging.

  • SAE quick disconnect lets you swap connector ends easily.
  • Alligator clips for temporary connections on exposed terminals.
  • Ring terminals for secure, stable connections on mounted batteries.
  • Lightweight cord and compact head for cramped battery compartments.

Who is this for: The Unocho 12V 750mA charger is made for vehicle and equipment owners who need a reliable, low‑current solution for routine charging and long‑term battery maintenance. It fits riders, weekend drivers, boaters, lawn care owners and small‑fleet operators who store machines seasonally and want a plug‑and‑forget charger that protects batteries while preserving life and readiness.

FAQ

Q: Can I use this charger on lithium batteries?

A: No. This Unocho model is only for 12V lead‑acid types (AGM, GEL, SLA, VRLA, WET), not lithium.

Q: Will it maintain a battery left unused for months?

A: Yes. After charging it switches to float maintenance to keep 12V lead‑acid batteries topped during long storage.
