Battery Tender, the best Accessory for your Bike

Well it is getting to be that time of year again when we look for ways to keep our  batteries from complete and utter annihilation. The question is often posed, “What can I do to keep my battery from going dead?” And while the answer is simple, not enough people are aware just how easy it is. K and G Cycles ( has what is referred to as Smart Battery Tenders. The most popular of them being The Battery Tender Jr produced by Deltran.

The complete line of Battery Tender Products has risen to the top, and continues to be the mark by which all others are judged. The reason being is Deltran, the maker of Battery Tender Products has employed “Smart” Technology in the production of its units. The Battery Tender Plus (BT Plus) is a battery charger that has a microprocessor controlled power electronic circuitry which enables it to preform and safely control a number of sophisticated charging functions, well beyond the capability of inexpensive trickle chargers.

Once you’ve connected the BT Plus and 4 bank battery tender boxsupplied AC power, it first conducts a number of checks during Initialization Mode to ensure that the battery is functioning normally. Then it will deliver its full charge at a constant rate of 1.25 amperes. This is called the Bulk Charge Mode. The battery voltage will rise and when it reaches a predetermined level the BT Plus will hold the battery charge voltage constant at that level, allowing the charge current amplitude to drop. This is the Absorption Charge Mode. The Absorption Charge Mode is complete when the charge current drops below a very low value, usually below ¼ ampere. Some BT Plus models have timers to limit the duration of the Absorption Charge Mode.

After the current drops or the allotted time expires (typically several hours), the BT Plus automatically switches to a Float / Maintenance Charge Mode. The purpose of the Float / Maintenance Charge Mode is to maintain the battery voltage just slightly (typically between 1/10 and ½ volt) above where it would be if it were fully charged and sitting at rest. This keeps the battery topped off at voltages well below the gassing voltage of a lead acid battery.

Based on price alonBattery-Tender motore, trickle chargers often appear to be a better economic choice for the typical consumer, but trickle chargers do not have the advantage of sophisticated electronic control. Therefore, as they allow the value of charge current to trickle down to what appears to be safe levels, the output voltage of the charger may very well rise to an unacceptably high level, sometimes even going higher than 16 VDC depending on the charger type and the battery that is connected to it. This magnitude of voltage is far above the gassing voltage of a lead acid battery. If the battery remains connected to this high level of voltage for an extended period of time, extreme damage may be done to the battery. Without Battery Tender type electronic safety controls, what appears to be an initial cost savings for the charger may actually cost several times the charger price in replacement batteries.

So you see, there is so much more than you think in these little packages many use to keep their batteries maintained. A Battery Tender just may be the smartest money you spend on your bike. As Ron Popeil used to say, “Set it and Forget it”. With a Battery Tender installed on your ride, you never have to worry about your battery again.
