are Maintainance-Free Batteries really better?

example: Delkor
or mas okay parin yung low-maintainance?

M-F Batteries should not and never be recharged except for your alternator. It doesn't have the right exhaust holes for the fumes and heat. Some opt to open the sealed covers which voids its Maintenance-Free, and end up with ordinary batteries after.

On the other hand, you wont have to open six holes just to check its water level. An indicator tells when it needs to be changed. This is better for those drivers who just sit and drive; and don't-know-how-to-open-their-engine-hood people.

Id take maintenance free any day over their regular counterparts. Just make sure that you get the high-capacity ones. Im using the red motolite right now, forgot what its called, OK naman! I cant see why anyone would get the old skool batts.

I believe those red ones are named Super Power M-F. Almost all batteries sold nowadays are M-F ones (the old classic refillable ones are still available). I think only the Outlast brand doesn't come up with an M-F yet.

BTW, those red ones are replaced by Motolite Gold. :D

Ah ok :D When i got them, they had the highest Capacity ratings. I also noticed, less yung sulfation sa mga terminals compared to the old type batts.

And at the strange angles we operate our vehicles in, mas maganda ang MF kasi walang leak. Yung sa Besta ko dati nag-leak kinalawang ang fenderwell. Same case with vinj's Frontier.

MF ako, bukod sa performance ng battery it doesnt f*ck up the paint under the hood.

how about yun MF na motolite na tropicalized, anyone own or tried this one?

Yes, maintenance free batteries are definitely better. They are sealed better than low maintenance batteries resulting in less water loss and less corrosive precipitate formation. You can just drive and forget about them until of course they die down and needs replacement.

I hope marevive yung thread na to as I find it very useful and education. My question is, I bought a Dyna Power MF Calcium battery just this May 2016, this is the first MF battery which I used since I had my first car. I had it installed on a Corolla Small body. I noticed that the two small holes on its upper sides emit lots of precipitates/fumes. Not sure if the water coming out of the holes is acid, distilled water of the battery or just precipitates/fumes. Luckily it doesnt cause corrosion on the fender of the car where it was emitted as well as the relay box directly on its side. Is it really normal for such kind of battery to emit too much water? At first I thought it was my water reservoir which is spitting water then I just noticed that it was the battery. Do I need to have it replaced by the dealer since it is under warranty?
