![]() ![]() What kind of battery life are you guys getting before changing? My first set went to five years before changing and my old converted bus even longer.Īnd if you have a bad cell, general what fails is one cell in a battery, the one cell will not come up to full charge, it refuses the charge. I need to decide whether to replace just the start battery or the tow deep cycle house batteries too. Is it important or just desirable to have the batteries in different banks the same age? My batteries are coming up on 4 years old and I think my start battery is going bad. Since the main reason for going the AGM route is to get away from battery electrolyte maintenance there doesn't seem to be much reason to change if you've got to maintain a regular lead acid start battery and my own personal opinion is that an outfit that sells this stuff should have shop capability for installation and preferably actually have the product in stock. I actually visited them to see what their shop capability was and was turned off by their inability to offer installation although they would be glad to order Lifeline AGM batteries at $650 a pop plus $100 shipping for the first one and reduced shipping charge for the 2nd. He said to simply install a lead acid type with suitable cold cranking capacity as the start battery. Is it necessary or just desirable to have the same type batteries in the coach starting bank and house deep cycle bank? The question arose recently while talking to a Lifetime dealer about the apparent lack of a Lifetime AGM start battery in the D8 size. We all know that one shouldn't mix battery types in the same bank and that it's desirable to have all batteries in a bank approximately the same age. All the other custom cable cutters I have found were just as expensive as Theft Marine or would take their time putting together custom orders. I wish I had known about this business sooner. I had to help a guy jump start his 40 foot Class A Diesel this past weekend with my coach and it took a half hour to charge his battery enough with my jumper cables to get it to crank in 25 degree weather after we nearly toasted my cables trying to do a quick jump start. I am thinking I could have him make me some really heavy duty custom jumper cables for a lot less money than buying the thinner 4 gauge jumper cable. His web site allows you custom order the length and various sizes of crimped lug ends. ![]() I might replace the wires in my boston whaler and few more cables in the County Coach because some of them are much longer than they need to be and this place makes it very affordable to do this. Located in Auburn WA and his internet site is Lawrence and his business is Greg's Marine Wire Supply. Great service with personal emails keeping me up to date with the order and shipping. I ordered a single 4/0 1 foot crimped cable to replace the (2) 3/0 cables, late Saturday night. He processed my order in less than 12 hours and had the order in the mail the next day. The shrink wrap was liberal and the very thick adhesive type. The 4/0 cable was the same quality as the West marine 3/0 cable but at 1/3 the cost and the lugs where 1/3 the cost and excellent quality and bigger ends. All the other suppliers of 4/0 welding cable I could find sold the wire in bulk and the shipping was way out there.Ī couple days ago I found this business on the internet that does all of this work for 1/3 of the cost and the crimps (die crimped) are far better than mine or the original ones on the country coach (stamped). Since West Marine did not have 4/0 cable I had to double up a 3/0 cable for the additional shunt to negative terminal on the inverter. ![]() I am running a total of 980amp hours with 4 AGM 8D house batteries. I had to crimp and shrink wrap them myself for the first time and they came out ok but it was not a die crimper that compresses the whole lug around the wire. I wanted marine grade cable because of the extra tinting on the copper wires and flexible cable like welding wire). What I ended up with is 3/0 gauge cable (the largest gauge they had). I recently spent over $250 dollars cutting and crimping some new battery cables at West Marine to add two more house batteries in my coach. ![]()
