Re: starting issues cbr954rr 135CCA battery enough?
You have answered your own question, it isn't enough. Honda fitted them with 190CCA battery. As batteries age they start to lose power. So while the 135 CCA battery worked in the beginning, as it aged it provided less and less and eventually got to the point that it would not start the engine. When you try to start a vehicle and the dash is going out, that is a telltale sign that the battery is no longer up to the task as it cannot turn the motor over and still provide enough power to run the dash. Think of it this way, the smaller battery has about 1/3 less power than the OE battery.
Go and buy a proper battery or go with a LiFePO and watch it crank over.
