Battery Maintainer: Powerful High-Tech Battery Tender Charger

When it comes to car battery chargers or other vehicle battery chargers, what most people think is that they areBattery Maintainer CTEK MULTI US-7002 8-Step Chart View going to hook up the charger to the car battery or motorcycle battery and simply charge it until the battery has enough juice to start.  What they don’t think of is that there is a reason that the battery is low in the first place and usually it’s because the battery was not maintained properly using a battery maintainer or battery tender.

A battery charger is good for getting a battery back up to charge, but in the long run, if you leave your battery unattended for long periods you will want to buy a battery charger that is also a battery maintainer or tender.

Battery maintainers typically run a smart program via a microprocessor that controls the whole charge process and automatically stops charging and goes into a maintenance mode when the battery is fully charged.

 

There are many great battery tenders around and we’ve got the articles for just about all of them.  Be sure and see our articles:

 

Regular battery chargers typically don’t do this and so once the battery is charged, the charger may detect and stop charging, but in any event, you should disconnect the charger to prevent damage to the battery or charger.

 

 

 

A battery maintainer will often have a series of steps to its charge process that may include desulphation which can prolong the life of your battery.

 

Some of the battery charging steps that are common in a good battery maintainer or battery tender are:

  • Desulphation – Possible reconditioning of batteries that have lost power due to non-use
  • Soft Start – Charges until the battery’s terminal voltage has risen to a preset level
  • Bulk – Primary charging step charges battery to a preset charge percentage below full charge
  • Absorption – The final charging state keeps voltage at a preset level
  • Analysis – Charging is suspended and voltage is measured
  • Recondition – Charger feeds a constant current to the battery and maximum voltage
  • Float – Constant voltage is maintained
  • Pulse/Maintenance – Charger sends a pulse of electricity to the battery when its charge falls below a preset limit to keep the battery in perfect condition for prolonged periods

 

There is one high-tech battery charger and maintainer that has the power to quickly charge your 12V battery while also being capable of maintaining your battery for maximum life and performance.  It’s a great battery charger and tender for car, truck, RV, ATV, marine, and motorcycle batteries.
