Best Car Battery Chargers
Our first review looks at the Battery Tender Plus from Deltran. This is a neat little charger that packs 1.25-amps of power. This might not seem like much, but due to the way this car battery charger functions, it provides the same charging rate as a 3 amp one! The interesting thing about this charger is that it’s revolutionary. It was the first of its kind to instantly switch to a float/maintenance mode where it helps to maintain the battery charge. This feature is common in a lot of chargers around today, but it all started here!
This is a spark-proof battery, and it’s ideal for cars and other automobiles – such as motorcycles or scooters. The charging process contains four stages; initialization, bulk-charge, absorption, and float-charge. Essentially, the charger is initialized, then it starts the bulk-charge rate to take it to 80% fully charged, then it goes into the absorption stage automatically. Here, it enters float-charge where the battery continues to keep the battery fully-charged without causing any overheating or temperature issues.
You’ll know which stage the charger is in thanks to the lights displayed on the front of it. The best thing about this product is that you really don’t have to do anything. It’s all automatic; your only job is connecting it, which is made easier thanks to the two accessories included in the package – battery tender ring terminals and battery tender alligator clips. The Tender Plus works with all lead-acid batteries, along with flooded or sealed maintenance free ones. Also, you get an impressive 10-year warranty with it as well.
