Honda batteries often fail prematurely due to the "Dual Mode" charging system which reduces the alternator output in order to increase gas mileage by a very small amount. If your driving habits are mainly short trips you may not be getting enough "on time" at about 14 volts and so the battery will gradually run down to a point where it will no longer start the engine. If you drive with your headlights on the alternator will always be on at about 14.2volts and the battery will maintain an optimal charge. If it is not too late or inconvenient you can fully charge your old battery overnight with a battery charger of moderate size or even a trickle charger and you will probably get a lot more life out of it. Batteries should last ive years or even more.

Always drive with your headlights on
jump into conclusion that you have bad batteries.
