Old UPS as car battery charger

[aioshin]

Got my car battery drained for unknown reason yet and cannot start my hilander anymore, i dont have a battery charger but found this very old ups that has a none working battery. So i open the ups, removed the old battery and rewire so i can connect the + - wire to the car battery corresponding terminal hoping it can charge. Charged it for 6hours and it works, it able to revive my battery and start my car.

Just sharing coz its working.

ako naman i use an old 3SM batt for the desktop and kung merong brownouts as an inverter

gumagamit nga lang ako ng car batt charger after severely draining it as the charging circuitry is only designed for the smaller batt

Thanks for sharing bro.

I am using a 13.8V (12V) power supply to charge a "dead battery" for as long as all the cells are functional. This was the power supply I use for my HAM (rated at 25A).

The battery in this case acts as a "voltage regulator" and so the charging.....

good job! better yet get a hobby charger like the imax B6. i got mine, just a cheap clone, from hobbyking for something like $16. charges li-ion, nimh, lead acid, of various voltages. super useful

or if you can afford it get an iCharger of which i have 3 now they're just so frikkin useful

kumuha si TS ng 12volts dun sa secondary ng transformer ,tapos nilagyan kahit isang rectifier diode.pwede na...

Ang UPS, meron talagang charger for 12 volts, so no need to connect a rectifier or diode para makapag charge, you just need to connect the charging terminal to the car battery. Yun na yun.

Pinoy Ingenuity! Galing Sir! Ma try nga sa Genset Battery namin, nasira na kasi yung float charger nya. I believe pareho din naman yung functions nya.

Very good idea. Just be aware that not all UPS uses 12volts dc as supply voltage. When absolutely certain that the UPS has 12 volts dc, your car battery will even charge faster if your 220v ac supply into your wall outlet.

We should always use a Voltmeter so we are certain that it has 12 VDC or even 14VDC available from the charging terminal of the UPS we are going to re-use.

Ok ito ah. Meron ako UPS pa naman. Masubukan nga. Hiram lang ako voltmeter.

Been using this continuously in our gensets for 27 days already and so far so good. Sulit na!
