This mains battery charger is compatible with
Lead Acid batteries
AGM Batteries
Gel Batteries
Wet Cell Batteries.

Additionally, this charger stands out from many others as it provides a stable charging voltage without peaks, ensuring a consistent and smooth charging process.

First, this 20a 12V automatic multi-stage mains battery charger revolutionises charging through its advanced 7-stage process.
The battery charger will remain operational as energy is consumed from the battery. It will sustain the charge should the battery be fully charged.

The boost-charging feature represents an initial charging phase that can enhance battery condition and restore lost capacity in older batteries. It optimizes the charge delivered to the batteries, thus extending their lifespan and averting early battery failure.

Meanwhile, it connects seamlessly to any 220-240V AC mains power source for efficient battery charging.

Extra Features of the 10a Battery Charger

Dead battery recovery involves a desulphation stage that can break down the sulphation occurring in batteries left discharged for extended periods, restoring them to full charge.

Furthermore, the charger eliminates voltage fluctuations while delivering faster charging times.

Automatic temperature control ensures the maintenance of an optimal internal temperature by automatically activating the built-in fan when high temperatures or charging currents are detected.

LCD Display: shows vital information regarding the charging process. LED lights also indicate the battery type.

Additionally, you can charge either a single 12V battery or multiple batteries in parallel. However, these batteries must share the same type, capacity, and age.

Moreover, this versatile charger works perfectly with all Lead Acid batteries, including AGM, Gel, and Wet cell.

Key features:

• Initially, built-in safety features protect against DC short circuits, overheating, and overcharging.
• Subsequently, the system maintains peak-free charging voltage for smooth power delivery.
• Furthermore, the charger continues working even when power is being drawn from the battery.
• Next, its boost-charging feature actively enhances battery health and restores capacity in older units.
• Meanwhile, the desulphation stage effectively revives batteries that have remained flat for extended periods.
• Additionally, an integrated fan activates automatically when detecting high temperatures or charging current.
• Similarly, the LCD display shows crucial information about charging voltage, current, and various stages.
• Finally, the power pack function enables direct powering of 12V loads without requiring a battery.
• 20a Battery Charger

In conclusion, LED indicators clearly display the battery type for quick reference.

Consequently, this feature proves especially valuable during battery replacement procedures.

This charger comes with a 1.5m mains AC cable with a UK 3-pin plug, a 0.5m DC battery cable with crocodile clips, and spare fuses for added convenience.

How does a Battery Charger Work?

• First, a 12V battery charger mostly takes power from 240v mains power supply and converts it to charge the battery safely. This can be 12v, 24v and higher
• Then, it pushes electricity into the battery, filling it up with energy to keep it powered. The battery then stores the energy ready for use.
• Often, smart chargers use a multi-stage process for faster, safer charging and to avoid overcharging.
• Plus, they protect the battery from damage, keeping it in good condition.
• Some chargers can even revive old or low batteries, extending their life and improving performance.
