SL-2A12

Spanker 12 volt lead acid

The SL-2A12 is much more than a compact conventional trickle charger for 12 volt lead-acid batteries. This fully automatic charger has been repeatedly used to bring back to life many weak, useless batteries when other chargers could no longer charge them to a small fraction of the original capacity. Better yet, use this charger on your good batteries to keep them functioning in top condition. Repeated tests confirm again and again that the RC-2A12 lets you have a whole lot more out of your 12V batteries. Designed for 20 to 125 amp hour batteries.

• Universal portable power supply accepts 110-240VAC input.

• Easy-to-read LED status displays state of charge.

• Lightweight and very portable. Approx. 2lbs.

• Physical - 3.25"W x 2.75"H x 4.5"D (excluding external power supply)

Pricing for single quantity without shipping $250.00 USD

Comparison Test

118% MORE POWER

DELIVERED TO THE BATTERY WITH SPANKER OVER STANDARD CHARGER

COMPARING TOTAL AMP HOURS OF POWER IN THE BATTERY

54.79 AH STANDARD CHARGER ---------       64.62 AH SPANKER CHARGER --------

The above comparison test was done with an 85 amp hour automotive type lead acid battery using a computerized battery analyzer which shows the total amp hour capacity. First the battery was charged with a standard 2 amp 12 volt automotive battery charger and then totally discharged to 10.5 volts. Then repeated with the same battery again with the Spanker. Both chargers had a similar power consumption of around 55 watts to bring back this fully discharged battery in a 48 hour period.

As you can see the Spanker in slightly less time improved dramatically the state of the battery as revealed in the Specific Gravity measurements and gave almost 20% more total amp hours of power in the battery. It's important to note that this is only a single charge cycle and that subsequent charge cycles with the Spanker will continue to increase this battery's capacity, whereas using the standard charger will continue to see a decline in the battery's capacity.

Use of the Spanker thus will maintain a battery in an optimum desulfated state allowing for a greatly extended life of the battery.    Learn more about what this technology does
