Deltran Battery Tender Plus 6-Volt 1.25 Amp Battery Charger Harry Potter7

Product Description

Constantly monitors battery without the damaging effects of trickle chargers (a trickle charger will eventually boil dry or overcharge a battery) The voltage output compensates for temperature changes- providing additional protection Initial charge brings battery to full charge at approximately 14.2V After full charge is reached- converts to float charger and monitors battery at 13.2V Although a constant charge is being applied to the battery- there is little or no current (approximately 10mA) Periodic maintenance is recommended- but Battery Tender Plus can monitor a battery for years without the fear of boiling or destroying the battery 12V Battery Tender Plus has fused quick-disconnect rings with a weather cover Optional pouch for safe and easy storage or transportation Photo`s are for reference only.

Customer Reviews

Monitored Battery Charging
A Battery Tender will constantly maintain a battery without the damaging effects of a "trickle charger". Full charging initially at 1.25 amps (7.25 volts), the charger will switch to a float-charging mode of 6.8 volts to monitor a 6-volt battery. When the battery is accepting only 0.5 amps, the charger's float mode will decrease both amps and voltage. The amp rate will drop to virtually no current (0.10 milliamps), and the voltage rate will drop to 6.8 volts.
~ The "gassing point" of a 6-volt battery is 6.9 volts. Therefore, applying any voltage greater than 6.9 volts for an extended period of time will overheat the battery and warp the separator plates, permanently damaging the battery.~
(Note: This last paragraph above is the diagnosis for why 99% of all 6 or 12 volt motorcycle batteries fail after only a short life. People unknowingly use a standard 6 or 12 volt battery charger on their new battery - which overheats the battery and permanently warps the separator plates. Use a Battery Tender from day one and your battery will outlive it's warranty period.)

I also recommend using "Charge It"(AGL890277Y), a cadmium additive from J.C. Whitney.

Directions for 3-cell, 6-volt M/C batteries:
"Use 1/3 of a 2.5 oz. bottle of "Charge It" into each of the three battery cells BEFORE the acid (electrolyte) is installed. Each cell receives 0.833 fluid ounces of "Charge It" and 7.167 ounces of acid.
Note: By adding "Charge It" into the battery first, you will only have to fill the battery with acid up to the upper level line, instead of having to measure exacting amounts of each." - 1941-1959 Mechanics & Owners Guide to Harley-Davidson OHV Big Twins - Vol. 1
