Battery Tender Plus 021-0128

Powerful Response to Battery Discharge

The Battery Tender Plus 021-0128 is one of the best trickle chargers on the market today, thanks to its reliability and power output, hence, it will be suitable for motorists of all sorts, so let’s break down why it is so good. First of all, this 1.25A trickle charger is capable of powering up motorcycle, car, and even truck batteries twice as fast as the competing models with lower amperage.

The simple yet convenient interface of the appliance features two indicators that will show the charging status of your battery, while the fault indicator will signal any problems in the electrical circuit.

Although this model can be used for almost any vehicle that features a lead acid battery, the jumper cables might be a bit small for car batteries. In case you want to use the charger on your car, we recommend double-checking the alligator clips when you connect them to the pins of your vehicle’s battery to exclude the risk of electric discharge. Alternatively, you can purchase any 12V jumper cable set for using it on your car specifically. Nevertheless, the float charging process doesn’t need the clips to firmly grip the connectors, unlike regular jump starters. That said, it is important to not touch the metal parts of clips during the charging process since there is a risk of an electric shock.

To wrap things up, the Battery Tender Plus can become your vehicle’s best friend that will protect its battery from reverse polarity discharge, sparks, and short circuits. Regardless of what type of car or bike you drive, this all-purpose charger should do the trick.

Schumacher SEM-1562A-CA

A Solid All-Purpose Choice

Engineered specifically for small to medium vehicles, the Schumacher SEM-1562A-CA trickle charger can still easily maintain the charge of large car batteries’ without too much of a hassle. While the 6V / 12V charger maintains the discharge level at a minimum, the 1.5A float device will ensure that the battery will be charged quickly. So quickly, in fact, you won’t even notice that the charge was depleted in the first place.

When the powering up process has been completed, the device will automatically go into monitor (floating) mode to conserve energy. In case the charge level starts dropping, the appliance will keep the battery topped up. Although the tool is quite good in keeping the battery of your vehicle juiced up it will not charge a completely drained one. On the bright side, however, the charger comes equipped with two types of clamps - jumper cables and o-ring connectors, which makes it suitable for a variety of lead-acid batteries.

All things considered, with a weight of only 2.5 lbs this fully automatic trickle charger is a portable must buy for every motorist that cares about their vehicle. If you don’t drive enough to constantly keep watch on your battery level, the SEM model from Schumacher will do it for you, which makes it a top pick in our eyes.

Functional yet Simple

The Battery Tender Junior is one of the most compact chargers, which comes with the additional auto mode function. You will have no problems using this equipment since it doesn't require any special configuration or adjustment.

The charger has only one LED indicator, however, its two-color scheme allows displaying the complete information regarding the battery condition.

Taking into account the fully automatic operation of the device, all you need to do is connect charger clamps to the posts on your car battery with the corresponding polarity, and then plug the charger socket into your household outlet. Yes, it's that easy! The Battery Tender Junior comes with two pairs of different connectors, which are ring terminals and battery clamps, to offer you the selection of the common options of hooking up the charger to the battery terminal posts.

Speaking of the device automatic operation in more detail, before initiating the charging the Junior 021 performs additional diagnostics and checks whether the polarity is observed. Thus, even if you connected the cables incorrectly, the special LED indicator will warn you about the wrong connection. However, we recommend reading the operation manual carefully before using the unit. Another great benefit of the Junior is the manufacturer 5-year warranty for the product!

What Is a Trickle Charger?

A regular car battery operates in the temperature range of 30°F and 90°F, thus, even the slightest hike or drop in temperature can cause capacity damage and shorten its service life significantly. On top of that, with a self-discharge rate of lead-acid batteries varying between 8-20% of the total capacity, you will definitely need a tool that will keep them charged, especially if you don’t use the vehicle too often.

It can be a real challenge to keep the batteries of your steel horse charged, especially in the colder time of the year. In case you are living in an area where winters are severe you probably know how bad it can be when your car or truck just won’t start on the first try. A trickle charger will help you keep your vehicle’s battery charged and ready to go at any time.

Trickle charging can be crucial in case you rely on your car to get to work on a daily basis or in case you use your vehicle as a seasonal transport (motorcycles, ATVs, or convertible cars).

If you are looking for more sophisticated car gear you may be interested in jump starters and pressure gauges to keep yourself safe on the roads.
