Difference between a battery tender and a battery trickle charger


A  Battery Tender is a microprocessor controlled fully automatic charger / maintainer.when using a battery tender you do not have to worry about it overcharging your battery,when you have it connected. The advanced technology will bring the battery back to a full charge without overcharging and then float or maintain the battery for an indefinite period of time. The Battery Tender Junior and Battery Tender Plus come equipped with alligator clips and ring terminals for easy hook up! It is designed to extend the life of any lead acid battery.When using a motorcycle battery tender it is not uncommon to get an extra three to four more years out of the life of the battery,or any other battery that is commonly used in automobiles, ATV‘s, personal watercraft, RV‘s, boats, airplanes, golf carts, back-up generator systems, etc. Any vehicle or battery operated piece of equipment not used on a daily or basis is a candidate for a Battery Tender charger.

A trickle charger is typically a low-current (500–1,500 mA) battery charger. A trickle charger is generally used to charge small capacity batteries (2–30 Ah). Although they often appear to be a better economic choice for the typical consumer, 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 rises well above 15 VDC,(volts direct current) sometimes even going higher that 16 VDC depending on the charger type and the battery that is connected to it. Either voltage is well 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, even less than 1 day, extreme damage can be done to the battery. What appears to be a cost savings for the charger may actually cost several times the charger price in replacement batteries.

These types of battery chargers are also used to maintain larger capacity batteries that are used in automobiles,motorcycles,boats,lawnmowers,and so on.The current of the battery charger is sufficient only to provide a maintenance or a trickle current (trickle is commonly known as the last charging stage of most battery chargers) When shopping for a Trickle charger read the instructions,and see if you can leave the charger connected to your battery for an extended period of time.Depending on the technology of the trickle charger,it can be left connected to the battery indefinitely.Some battery chargers that can be left connected to a battery without causing the battery any damage are also referred to battery tenders, or smart chargers

When working with lead -acid batteries be careful, Lead-acid batteries contain a sulfuric acid electrolyte, which is a highly corrosive poison and will produce gasses when recharged and explode if ignited.  When working with batteries, you need to have plenty of ventilation, remove your jewelry,(to avoid creating a spark) wear protective eye wear (safety glasses) and clothing, and exercise caution. Whenever possible, please follow the manufacturer’s instructions for testing, jumping, installing, charging and equalizing batteries.
