Best Trickle Chargers Buying Guide

We gave you an insight into the best trickle chargers. Here are a couple of things you should keep in mind when choosing the right trickle charger for your needs:

Engine Size

First and foremost, the problem you are getting a charger for is cranking the engine. A bigger engine draws its power to start from a bigger battery. A bigger battery hence would require a bigger battery charger. The bigger the engine, the more powerful charger you should be getting.

best trickle chargers

Therefore, before buying a trickle charger, make sure that it is suitable for the size of your vehicle. A motorcycle engine battery is small and would do fine with a one-Ampere trickle charger. Moreover, the same battery is used in scooters and golf carts.

But, if you are going for a battery for a two-liter engine, you need to have at least two Ampere trickle charge capacity and a preferably higher fast charge capacity on the charger.

The fast charger can help recover the battery from a deep discharge, and then the trickle charging mechanism of the charger can maintain the charge.

Battery Type

The other thing to bear in mind is the kind of battery being used in the system. Some chargers might be good for a lithium-ion battery but would not perform well on a lead-acid one. Spending money on something you cannot even use afterward would be a waste of money.

The rule of thumb when buying a trickle charger is that lead-acid batteries are compatible with all kinds of trickle chargers. The problem arises with gel and calcium batteries. If your vehicle uses one of these solutions, then go for gel or calcium battery-specific chargers.

Usage

Not everyone needs a trickle charger. If your car is driven daily, you do not need one. A trickle charger is needed to start the machinery that lies around for so long that the battery dies. So, trickle chargers might be needed by someone with golf carts that aren’t used frequently or an antique car that only goes around the town once a month.

Many adventure enthusiasts use trickle chargers on their SUVs that are not driven daily. Daily driven cars do not require trickle chargers, this is because they charge up their batteries through their alternator as they drive.

It might be a perfect thing for your occasionally used car. Connect a good trickle charger to the car battery, so it is ready for some DIY experimentation whenever you have the time. However, you might be needing some oil change, paint touchups, and other work done before it can see the road anytime soon.

Types of Trickle Chargers

There are two different types of trickle chargers on the market.

  • Traditional Charger

Traditional trickle chargers are ‘dumb,’ which means they cannot ‘see’ what is the charge status and will keep sending out charge to the battery. As a result, the battery may overcharge, and in extreme cases, can even be a safety hazard. The chargers cannot read the charging status from the battery and derive their power from the mains.

You get the advantage of charging anything or everything with these traditional chargers as they will dish out charging to anything that is at the end of the two charging wires.

  • Smart Charger

Smart trickle battery chargers are much more advanced than traditional ones. They have updated designs and keep tabs on the battery percentage as they charge it. This information can help the charging systems prevent overcharging. Because of the added functionality and features, they are priced higher.

Smart chargers can increase the life of a battery. They do not need any supervision and are fairly simple to operate. Moreover, they adjust the voltage and current to suit the needs of the battery.

The only downside to a smart charger is that it cannot charge any battery size like a traditional charger can.
