What Is The Lifespan Of A Battery Tender? | Answered

They have an identical lifespan to every other electrical equipment. Possibly dead forever or dying at any moment.

Battery tender is a device which is used to charge and maintain the charge of a lead acid battery. 

Most battery tenders on the market today are fully automatic, meaning they will shut off when the battery is fully charged and turn back on when it needs to be recharged.

Lead acid batteries are found in cars, motorcycles, lawnmowers, and other small engines. 

A battery tender differs from a standard charger in that it will not overcharge and maintain the battery at full charge without damaging it. 

Battery tenders are also known as “smart chargers” because they can be left connected to the battery indefinitely without damaging the battery.

The first is the amperage or charge/discharge rate, which is a user-defined setting and easily adjustable.

Second factor is an internal circuit breaker that will eventually malfunction.

The tender automatically turns off after the battery is fully charged and won’t turn back on until it has cooled off. Thus this kind of failure is uncommon.
