Cheaper alternatives to Motolite Gold 21 on a 2009 Kia Picanto MT

[grss1982]

Back in Sept. 2017, I bought a Motolite Gold 21 for my 2009 Kia Picanto (MT). It died on me this month which is sadly not within warranty. So I traded it in for a new one. However, I think this will be my last one because with a trade in discount this battery is freaking expensive at P4,400.

I was wondering if there is any cheaper alternatives to this battery that's available locally? I'm from Cebu by the way.

My Kia Picanto has one of those locking mechanism in the battery tray that clamps to a tab at the bottom of the battery so I can't just go for the cheaper brands because I can't secure it to the battery tray since the cheaper one I've looked into do not have that tab on the bottom. Most battery brands I've looked also do not have this tab at the bottom. The tab I'm talking about is the one circled in red in the attached picture.

I really wanted to go with the cheaper Enduro but it did not have this tab. It was cheaper by P1,000 than the Gold 21. I was also considering a Panasonic battery but it also did not have the tab.

So here I am now asking folks here for help and feedback if there are any other cheaper alternatives for my future battery purchase for this car? If it helps the Picanto is my daily driver to work (Mondays to Fridays averaging 30KM a day). City driving.

Thanks for any help.
