Re: replacing batt's
When you replace your battery go with the best rating
you can afford.The less a battery is discharged before charging the more charge cycles it can go through.
The better the battery the longer it will take to discharge,I feel the best deep cycle for the money is the Trojan and the 30 XHS is an excellent choice.
It is a 130 amp hour battery with a 225 minute rating.
It is pricey at about $150.
