I would go with a bigger charger and one that has an auto setting. There are some that also have an auto-deep cycle setting. The auto is nice cause you can leave it without keeping checking. The deep cycle setting allows a very high volteage finishing charge , at the end of the charging ccyle. That's suppose to be good for the battery. I never heard of a 2 amp battery , just 2 amp trickle chargers. The trickle chargers are also suppose to be good for the battery but they are sooooo slow they are imprcatical IMO. In season , you are going to want to recharge the battery fast for another use. I say 10 Amp minimum and up to 20 if you can find one at a good price . Automatic is worth it. Keeps you from overcharging which will eventually cost you battery life.
There is some logic in getting a big but cheap battery. what you want is AMP-hours , not cold cranking amps. Its how much energy total the battery will hold , not how fast it will delivery it. Cold crank is important for starting a car in the cold but for running a pump , its Amp-hours.
I think its the off season that kills the batteries. If you were contimously using the battery and recharging , they last a long time. A couple of winters stored without use is what kills them.
