a battery "ready to go" deteriorates with time, even if it is not used.
if one wants a replacement battery on hand for justin (just in case), one can have a battery, but with the electrolyte not yet poured in. this allows the battery to sit there for many years, with minimal deterioration. you pour the electrolyte into the battery when you need it.
Another problem would be that it shortens the warranty, it's already running the moment you bought it

Umabot sakin 44 months (hindi pa ubos pero nagpalit nako)
Twice a week ko lang ginagamit (before covid) pang mall and church lang. Then nag covid, mga twice a month na lang pang grocery. Not bad!
Pero ako na ang sumuko wala na ako peace of mine. Hindi ako sanay kasi before lagi ako motolite na laging sakto tapos na warranty na uubos.
Nag palit nako kanina amaron ulit![]()
mga ka-tsikot ask ko lang. 2015 fortuner MT 2kd-ftv. stock wala naman ako accessories na power hungry like a killer sound system.
worth it ba mag 3sm pa na battery or balik 2sm uli from the factory? amaron pa din. libo din kasi price difference. salamat
If the stock battery is 2SM, you'll be fine with a replacement 2SM. Practical advantage lang ng 3SM is the bigger reserve capacity and cranking Amps. Depending on actual use, the additional capacity may offer some insurance in starting the engine even if an accessory was left on overnight, for example, or if you run into an engine issue that requires you to crank it longer than usual.
It's up to you if you feel that the extra capacity is worth its weight (literally) in Pesos.
FWIW, I have a 3SM Amaron in my 2.5 Innova G.

issue with installing larger battery: kakasya ba? will the battery footprint be accomodated? will there be enough room above, so's the metal hood won't touch the terminals?
will a larger battery result to longer battery life in that vehicle? i do not know.
the larger CCA might result in chronic under-charging, which predisposes to faster battery deterioration.
i do not know.
in my non-diesel sedan with only a stock radio as electrical toy,
i install the next smaller size battery.
over the years, i did not perceive a shorter lifespan.

I would just stick with using the same battery size
Unless there is no stock of the correct battery and there is no choice

From what I understand naka 3SM na ata si babkalakal ngayon, so it will definitely fit, and the alternator is definitely capable of charging a 3SM battery.
His question is if it's worth it to continue using a 3SM or go back down to stock size of 2SM.
If the car is frequently used, there are no accessories with big power draw, and accessories aren't operated on battery for extended periods I vote to save the money and size back down.
