At 18100 Kms, my batt suddenly went defective (low voltage). Nagkaroon kasi ng hesitation sa pag-start (when you press the Engine start/stop button) for about two or three times. Good thing, my dad bought a Panasonic 2SM MF batt (to replace his 4 or 6yo Bosch Silver - pero alternator pala prob nya) a few months ago. So I borrowed his batt (which is just stored in its box sa garage) thinking ahead that the casa might not have a battery on stock. Good thing I did kase although under warranty, 2-5 days pa dadating from the central warehouse replacement. So I asked a favor from Nissan North EDSA to temporarily swap the battery I brought kase I don't want the hassle of being towed due to a dead batt. Mr Dennis and Mr Winston obliged cheerfully. Great service from that dealership so my next Nissan will definitely be bought there.

One thing I learned from that experience, gumagana pala talaga yung power management system ng Sentra B17 natin. Accdg to the manual, it will allocate and reserve starting-power when the battery charge drops (due to usage when the engine is off). In this case, kahit due to batt defect, gumana pa rin.

Also, that GS Battery sucks. 1yr palang dead na. Ako nga pala ang 2nd case sa dealer na nasira agad batt kahit all-stock.

Anyone else got B17 issues? Been seeing quite a lot of new releases lately (no plate yet).

Eventually, I went back to stock tire pressure (F33-R30). Didn't really see any fuel mileage gains in city driving. Siguro try ko ulit mag 36-33 pag may out of town trips.
