Battery Maintainer 12 Volt. Waterproof - Prevents Sulphation

Final bid

Special auction for for two units.

By maintaining full float charge further sulphate buildup is eliminated, and by maintaining the high level of charge sulphate can be redissolved. Waterproof, the electronics are fully encased in a wax-like material!

This little unit is rated at 12 volts 1.5 amps DC output, and is ideally suited to maintaining batteries up to 250 AH in size. It also has the ability to charge small batteries up to 30AH in capacity Corolla NS40/NS60 size BUT don't expect this little unit at $40 to overcome & look after and fix a dead or near dead battery... You will cook it. Sell my other listings for the Pulse chargers that are correctly rated and with the time per phase capability..

It is supplied with a NZ approved 3 pin plug with a 1.6M lead.and the perfect little gadget for the battery boat or camper-van batteries whilst they are in hibernation waiting for the warmer weather. I so often see in my battery shop little NS40 batteries in small cars lasting 5 years & yet expensive marine units hardly doing two seasons. It is because they are not used over the winter & they are simply allowed let go flat, or become heavily discharged.

This TE4-0221 will fix all of that! Remember an ounce of prevention is worth a ton of cure...and is perfect product for vintage & classic car batteries, it will ensure that your vehicle will start even after extended periods of non use.

Put one on the battery of your stand by generator, fit and forget, & it will start in the dark at your next power outage.

It is fully automatic in that it will will enter into a float phase after charging, that will maintain the battery at its fully charged state. It has LED indicator charge level status lights.
