A trickle charger for car recharges the battery over a period when the car sits idle. It will automatically recharge the battery, not allowing it to lose the remaining charge. There is no definite time length for how long you can keep a trickle charger attached to the battery; for that very reason, different chargers are available in the market. Before using the accessories, it is important that you know how to use a trickle charger accurately.

Guideline To Use A Trickle Charger With Some Simple Steps

The first step is knowing what type of trickle charger you need. If you are planning not to use your car for a long time, then you should not buy a trickle charger that is manufactured aiming at short term purpose.

Trickle charger for car recharges a car and a motorcycle battery at a rate that is parallel to the rate the battery gradually discharges itself. So, it maintains the optimum charge level in the battery. Recharging the battery at a rate faster than usual, or overcharging can permanently damage the battery.

To use a trickle charger, you only need two alligator clips and a power cable – which are likely to be at your disposal. Carefully check the switches to see if everything is alright before you connect the device to a power source.

To ensure efficient and safe trickle charging, find an appropriate place to attach a trickle charger to the car. One of many driver’s bad habit that “destroy” car battery is to drive with a loose battery. For that reason, take a closer look at the battery before selecting a location.

Step 3: Attach Cables

Firstly, attach the alligator clips. Now take the red clip and connect it to the positive terminal. Once you have successfully established a connection, connect the black one to the ground location. Before you plug in the charger, make sure you attached the negative wire solidly. Never touch the wires while the trickle charger for the car is plugged in.

Step 4: Turn on Charger

Follow the trickle charger instructions to see if the settings are just. Now plug in the car trickle charger and push the ‘on’ button. The amp reader will clearly indicate if the battery is low or high on charge. If the reading says low, it is likely that the ground connection is not adequate. Disconnect the charger and do it all over again.

    The picture above of the Schumacher Trickle Charger is the exact one I purchased. The included instructions & yours doesn’t tell me what the cable with the two circles are used for. Considering they have a red & black wire (negative/positive) what are they for? Don’t use my car very much and it has something draining my battery, which no one has been able to find, so just leaving it over the weekend, come Monday I need a jump start. I waste more gas just sitting in my car running it for 20 minutes just to charge my battery. Purchased thus charger over two weeks ago and still don’t feel comfortable to connect it. Not mechanical at all. H-E-L-P
