Who makes the best car battery charger?

Dead batteries are a common problem with vehicles that sit for long periods of time.

Allowing batteries to fully discharge shortens their lifespan, and having to jump them constantly can be a hassle.

Riding lawn mowers, motorcycles and vintage cars will all benefit from an auto battery charger like Deltran's Battery Tender Plus.

The Battery Tender 021-0128 Battery Tender Plus, is perhaps one of the most advanced battery chargers available. It is especially designed for today's sealed lead acid batteries. The Battery Tender Plus uses a microprocessor to maintain the charge in any 12V battery without overcharging.
Best Car Battery Charger - 12V Auto Battery Charger by Deltran
When the battery is fully charged, the 021-0128 Battery Tender Plus automatically switches to float mode to safely maintain the battery's charge.

Unlike most trickle chargers, which can overcharge and damage the battery if left connected for prolonged periods, the Battery Tender Plus can be safely left connected to the battery for a long time.

Red and green charging indicator lights make it simple to tell when it is charging and when the battery is fully charged. This 1.25-amp charger is much easier on batteries than other chargers, but it charges batteries just as fast as any 3 amp charger. The tender comes with a quick connect harness that can be used in hard to reach areas.

Features of the Deltran 021-0128 Battery Tender Plus:
  • Automatically switches to float mode once battery is fully charged
  • Reverse polarity protection for user safety
  • Charge indicator lights show charging status
  • Quick connect harness
  • Ring terminal and alligator clips included
  • 10-year warranty
  • Retail price: $59.99, Amazon price: $44.99

Extreme temperatures and prolonged periods of inactivity can cause a 12-volt battery to lose its charge. With the Battery Tender Plus 12-volt Battery charger, you can easily charge and maintain your batteries so that jump-starting is unnecessary.

Having previous experience with the Battery Tender, I would have to say that in my opinion it's the best car battery charger out there.
