How Do I Know When To Stop Charging?

The KeyLine Auto-Switching SLA Battery Charger features a 3-step smart charging process that will: 

1) Diagnose your battery voltage. 
2) Charge the battery. At a rate of 7.2-7.5V/14.3-14.7V) until the battery reaches a full charge and then
3) Float with automatic monitoring. If the voltage drops below 6.7 (for 6V) and 13.5 (for 12V), the charger will maintain the voltage between 6.7-6.9V/13.5-13.8V to keep your battery fully charged.

The KeyLine Auto-Switching SLA Battery Charger features an ultra-bright LED lamp to indicate the charge level, and when the battery is fully charged. Just set it and forget it… It’s THAT EASY!

NOTE: Although this is a smart charger, and will not damage your battery, we recommend that you disconnect the battery after the indicator light turns GREEN (fully charged) as the KeyLine Auto-Switching Charger is specifically designed to charge the battery, NOT maintain it. If left for long periods of time (days not hours), the battery can over charge. Unlike our competitors, that only claim to make “smart” chargers, KeyLine Chargers Auto-Switching SLA Battery Charger is the only mini battery charger on the market today that features this exclusive 3 step plug & go charging process.

Not only that, but all KeyLine Chargers are backed by a full 1-Year Warranty. So buy KeyLine and buy confidence!

 

Why Buy From Us?

Hello From the Owner

What our Amazon customers are saying about us...

"The Keyline Mini-Pro Automatic Car Battery Charger is elegantly simple in design and beautiful in its packaging. The single page of instructions and the minimal "warning" paragraph were more than adequate for the device. The charger itself is completely protected from electrical abuse and will not harm the car battery under any conditions..."
Robert

"Great product. We started using the charger right away and it is working great. It arrived on time, which is a plus during the holidays!
Everything as stated and then some. We had questions that were answered in a timely fashion before purchase. Would recommend this product and seller to everyone I know!"
Michelle

"This is a very user-friendly unit. It has a cord on both sides of the transformer so that it does not take up 2 outlets. Well designed. I love the consumer-friendly consideration. Permanent battery connection for the generator battery was very simple to connect and the appropriate cords included. I purchased 2 units and am very glad I did. It comes with an outstanding 5 year warranty! That is standing by your product! The price is very reasonable. The cords are reasonably flexible. The face of the unit is also user friendly and easy to read. A+++++"
Gerald

"I bought the KeyLine charger to charge up my battery packs to my home alarm as well as to the ATT box. Honestly I did not know they were rechargeable as I had already purchased replacements for them. When I was about to turn the old ones into be recycled is when I saw that they were all rechargeable thus I ordered the charger. It charged them right up so I am very happy with my investment."
