Things to Consider Before buying a Good-Quality Trickle Charger
With the ‘smart charging’ and other multi-protection features in trickle chargers, you can avoid over-heating of batteries. Some premium trickle charges have built-in thermal sensors that allow users to track the battery’s temperature during charging applications.
Microcontroller (MCU unit)
This unit works with a processor (chip) that records the charging process and battery’s performance. It often memorizes and displays the phases of any charging system.
Get trickle chargers with at least a four-phase charging system that shows percent (25%, 50%, 75%, 100%) levels from its MCU unit.
The quality of materials used in manufacturing any trickle charger determines its durability. While some chargers have great ergonomics, they could also have sub-standard parts.
It’s cost-effective to buy portable battery maintainers that have complete kits of accessories. Before choosing any product, ensure that it comes with spark-proof connectors, O-ring terminals, and alligator clips.
Types of Trickle Chargers
Since batteries are rated differently, they come in several capacities. Also, trickle chargers have specifications for all types of batteries. Here are some types of trickle chargers.
Smart Chargers: These types have ‘Microprocessor chips’ that can control basic charging applications. While a smart charger stops charging when the battery is full, it’s microelectronic circuit is an energy-efficient feature.
Also, this charger comes with intelligent LEDs and other features that can monitor the battery’s health, performance, and temperature.
Regular Chargers: They have basic built-in charging features and may take a slower charging time to complete the application. However, regular chargers supply constant direct currents (DC) to optimize the battery’s capacity.
Trickle Charger vs Other Chargers
The trickle charger works by supplying steady DC power, but it comes with enhanced features that make the application safer than normal chargers. Also, a trickle charger is compatible with several battery types. It works on the principle of sending trickles of charges to the battery.
When the battery reaches its peak charge, the trickle charger stops supplying electrical current automatically. However, the trickle charger resumes its activity when the stored charge depletes by any load. Unlike the trickle charger, other chargers might not prevent overcharging conditions.
How to Use a Trickle Charger
A trickle charger helps to regulate your battery’s charging rate, but the battery must be ready to be charged. Check the battery’s terminals, and set up your trickle charger without any loose connection points.
Avoid using worn-out power cables and alligator clips because they can cause short-circuiting of the connection. After ensuring the right connection, turn on the switch from your (Alternating Current) AC socket to re-charge the battery. If it’s not charging properly, the LED might indicate the fault.
Benefit of a Trickle Charger
Trickle charges prevent over-charging and provide sustainable battery maintenance. They are lightweight, portable, and ideal during an emergency. Additionally, multi-voltage trickle chargers (6V/12V) are more versatile than regular chargers.
Frequently Asked Questions (FAQs)
What are some common advanced features that come with smart trickle chargers?
Depending on the manufacturer, a trickle charger product can include safety and performance features. Some of these features that optimize your 6v and 12V batteries include multiprocessors and sensors that detect abnormalities.
Why is the trickle charger also called a battery maintainer?
Generally, the maintenance voltage that’s required by a battery is a function of its Full Charge Voltage (FCV). A well-built battery maintainer detects the amount of electrical charge that any compatible battery can hold. Also, it sends a trickle charger to the battery over a period of hours.
What type of trickle charger do I need for a 12V 50AH battery?
With such a battery rating, consider using a 12v 10 Amp trickle charger.
Can a trickle charger revive dead batteries?
It’s not every dead battery that can be revived with trickle chargers. When your battery has long-term deep discharge rates, the Microprocessor circuit of the charger might perform a desulfation. During the charging phase, this circuit often dissolves large particles of sulfate crystals that have accumulated inside the battery.
The best battery charger for the lawn mower uses a stable charging process. When the 12 or 6V battery reaches its threshold, the charger stops the flow of electrical current.
However, it resumes charging when there’s a drop in the battery’s charge level. Additionally, this smart charging process can extend battery life.
These top-rated trickle charger models require AC power to charge DC batteries, and they come with a complete set of accessories. Even in cold climatic conditions, many of these smart multi-voltage chargers prevent under-charging of batteries.
