Best trickle charger for motorcycle & riding lawn mower – maximum functionality
Before you choose a trickle charger for motorcycle or lawn mower, you need to know the difference between the chargers on the market today. If you choose from the above-written reviews – this is definitely the NOCO Genius G3500 6V / 12V 3.5A.
Its distinctive advantage is sufficient current and two voltage ranges. This charger is fully automatic, it starts, stops without pressing buttons. It DOES NOT recharge your battery, regardless of whether it is a car, motorcycle or lawnmower. It controls your battery voltage and performs a cycle if necessary. So, I think that it is the best motorcycle trickle charger.
What is a Trickle Charger & How to trickle charge a car battery?
Chargers are intended only for gradually charging the battery, their current output does not exceed 8 A. Attempting to scroll the engine with a starter while the charger is connected to the battery will damage it or trigger the built-in protection: the current consumed by the starter may exceed 100 A.
Trickle chargers, also called battery holders, can come in handy for charging cars, boats, RVs, motorcycles and golf carts. It has a low current level, the charger gradually charges the battery as it depletes energy.
Types of Trickle Charger
All car battery trickle chargers, regardless of their type, are required to provide a normal charging mode until it ends. Voltage and current are automatically aligned with the required parameters. All devices that are currently available for purchase are divided into two main groups: pulsed and transformer.
- Transformer devices are very reliable, but, nevertheless, they are not widely used. The reason is that they are very large and heavy, which is why it is not very convenient to exploit them.
- Most motorists prefer to use pulsed “charging”. They are much more compact, and also have a number of other advantages. Thus, the pulse device for the average user is much better, so that they are more common in the sale.
Nevertheless, those motorists who primarily value reliability choose transformer devices.
Trickle Chargers vs Normal Car Battery Chargers – what do you prefer?
Chargers for car batteries are usually installed in the range from 1 to 50 A for charging mode. Some may even have 200 amps, which is necessary for switching most starter motors.
If we talk about a trickle charger, it has a low current ratio, or it can only discharge the charge current. Most handheld chargers are discharged somewhere between 1 and about 3 amps. Some devices are called “automatic” or “smart” trickle chargers, unlike manual chargers.
Are Battery Maintainers and Trickle Chargers different?
It is worth noting that charging for the battery arose almost immediately after the development of the first lead-acid battery. Each charger works according to a fairly simple principle, according to which the voltage first decreases from 220 to 12 V and straightens. The charge is carried out by a weak current for several hours.
The main difference is that the battery maintainers will turn off the power source when the batteries are charged. It monitors the charge and when the charge drops to a certain level, it works again. It provides a continuous charge.
And how to charge the battery?
“Sat” battery … What could be a more unpleasant surprise before the trip? If you have a battery charger on hand, then solving the problem will not be difficult. And the regular and proper use of it is a reliable remedy for such annoying “surprises”. Charging a car battery with a charger is not difficult and inaccessible.
First of all, it is safety. Park your car in a ventilated room, because charging a battery can release additional gaseous hydrogen, which can explode after it is left in a confined space. Switch off the ignition and ensure that the charger is turned off.
How to use a trickle charger?
Set the appropriate current and voltage for your car’s battery. Select the desired charging mode, in accordance with the instructions for the charger. From time to time, monitor the process of charging the battery, and after it is completed, turn it off. When disconnecting the battery from the charger, first disconnect the negative cable.
How much time does it take to charge a car battery?
As for the optimal time for auto battery charging, this question is clearly and unequivocally difficult to answer. It all depends on the level of battery discharge and charging method. On average, the process can last 8-10 hours, and in some cases more than 12 hours. You can, of course, use currents of large magnitude, then charging will be completed faster, but this method has an extremely negative effect on the working condition of the battery and practices this method is often not worth it. Then very quickly, the battery will fail and will have to buy a replacement for it.
Charge time for motorcycle
The main question asked by almost every novice motorist is whether it is possible to charge the battery with a car charger? The answer to this question is quite ambiguous. On the one hand, car chargers with a current regulator allow you to do this. On the other hand, it is better not to start a new rider for such a recharge, since the procedure requires attention and experience.
For a normal battery charge, we need a current of one-tenth of the capacity of the battery. As a rule, a full cycle of charging a 12-volt battery for a motorcycle takes about 10-12 hours.
Overcharge battery with a Trickle Charger
Despite the fact that the chargers are very modern today, they are also vulnerable to overcharging the battery, which can cause serious damage to the battery. But I can recommend a battery regulator to prevent a decrease in the possibility of recharging.
Also, to protect the batteries from overcharging, each device is equipped with a special protection that automatically shuts it off when the battery is 100% charged.
