BatteryJack inc. Tank 10/2/50 Amp 12V Manual Charger battery charger

SKU CH-RN6R-JT5BT

A 12V manual charger delivering 2–50A charge rates and a 50A engine start for cars, motorcycles, boats and farm machinery

  • Three selectable charge rates for precise battery care
  • 50 A engine-start boost cranks stubborn 12 V engines
  • 120–230 V AC input works on mains worldwide
  • Rugged black-yellow casing built for workshop and field use
  • Suits cars, bikes, boats, farm gear and RVs

Manual 12 V charger with engine-start

The Tank 10/2/50 Amp unit delivers selectable 12 V DC output at 2 A, 5 A, 10 A, 20 A and 50 A, plus a 50 A engine-start boost for cars, motorcycles, boats, farm machinery and RVs. It accepts 120–230 V AC input at 50/60 Hz, so it works on standard mains worldwide. The manual selector lets the operator match the charge rate to the battery size and condition.

Simple bench connection with rate selection

Clamp leads attach directly to battery terminals; the front-panel dial chooses between five charge currents and the engine-start setting. The main mistake is leaving the charger on a high amp setting for a small battery, which can overheat the cells. Always verify the battery voltage is 12 V and select the lowest suitable current before switching on.

Sustained output holds steady at chosen rate

During extended charging the unit maintains the selected current without thermal fold-back, and the 50 A engine-start mode supplies cranking power for as long as the duty cycle allows. The metal chassis and internal components are rated for continuous operation at the listed outputs. It is not suited for unattended long-term float charging or for 24 V systems.

Questions about this item

How do I confirm the charger is delivering the selected 10 amp charge rate after setup?

Select the 10A setting on the manual control, connect the clamps to a 12V battery, and observe the ammeter needle settle at the 10 mark while the unit is powered from 120-230VAC 50/60Hz mains.

What cables and connectors are included in the box versus what must be sourced separately?

The charger ships with attached output leads ending in clamps and a mains lead for 120-230VAC input; no additional cables are required for basic 12V vehicle or equipment charging.

Which output setting — 2A, 5A, 10A, 20A or 50A — should I choose for a typical car battery?

Use the 10A or 20A charge positions for normal automotive battery charging; reserve the 50A engine-start setting only for cranking assistance.
