i was looking at upgrading from my oem battery. The ytx14-bs to a ytx20ch-bs .the difference between the two is the 14 is 240 cca and 12 Ahr the sizes seen to be the same . like (5 7/8 " L)x(3 3/8" W)x(5 3/4"H)and the 20 (6" L)x(3 7/16" W)x(6 3/8 H) .Now the 20 offers 270 cca and 18 Ahr. Has any one done this before . The next question i know it will fit but is there going to be and problems from the higher cca ??? Ifevery thing works out this might fix some like problems i have when plowing snow or using the winch

Shouldn't be any problems.It'll just turn over faster.

Yeah, it should work fine. Just make sure the negative and positive posts are on the correct side or the cables might not reach, but you could always put longer cables on, if needed.

a slightly larger battery should help, not harm. I would think it would still be able to charge and keep up with it. Im a diesel mechanic, I don't know as much about quads

This may not be entirely true, form a pure electrical point of view. The larger batter is still only 12V, so all things being equal the starter won't know the difference.

What will be different is that the battery will hold a charge longer, which may lead to the engine turning over faster if, for example, the smaller battery were to become more discharged, but assuming both batteries are in good condition, fully charged and the smaller battery was originally designed for the system, then there will likely not be any difference in crank speed.

Sort of long winded, but thought I'd throw that out there. :happy2:

^^^^^ Agreed. The 12v. system will not crank (turn over) any faster. The larger battery will have more amperage to draw from thus a longer cranking, (discharge) time.

I agree with everyone, but a bigger amperage battery won't hurt it, though.

good, im glad im not the only one who thinks so. I used to use my old worn out truck battery to start my ridding mower lol, it worked. Not sure the charging system would charge it. A slightly larger batt should give you longer cranking due to more cold cranking amps. I hate it when a battery lets you down. Let us know how it works,
