TC12150C - 12volt 130a/h - VRLA batteries good for a boat

Are these batteries good for amps on stereo ect?


I was thinking about getting 2 of them and 1 regular starting battery?

sounds brilliant but do you need 260 AH as an aux battery ? even if that stereo is rated 1000w it wont draw much current as that 1000w is probably PMP not RMS ..I always recomend you check the actual current draw at normal listening level with an ammeter before you deceide on the battery requirement. You dont say what boat or engine or how you intend to charge them ..off the boat I guess .

Here is what I'm trying to do.....run a 1000gph bilge, a Lowrance HDS-10 and about 15 watts of lights for 10 solid hours with out recharging. The outboard is a 1984 Johnson 75HP. The outboard will only be used to get up from fishing hole to fishing hole, so not very much

I wanted to run 3 12v 130a/h AGM batteries in Parallel

I can charge every night without a problem. Does this sound like i'm on the right track?

Every device you need to run from the battery has an "amp" rating. Look at the tag for that device and add the values for all of them. That is the A/Hr you will use. Multiply that number by 10 (the number of hours you need to operate) and that is the A/Hr battery you need. 15 watts of light is only a little over one amp. A 1000 g/hr bilge pump I will guestimate at 7 - 9 amps. Don't know what the HDS-10 draws exactly but I suspect 3 amps would be way on the high side. So if all of this was running at the same time you would draw less than 15 amps so a single 130 A/Hr batery would provide just short of the 10 hours you need. Since the bilge pump is the huge draw (in comparison) it will not likely be needed 100% of the time so figure 4 amps for it. This brings you down to 9 amps total to the single battery now would power things for over 13 hours. You need two only if you didn't tell us everything you intend to power -- such as a marine radio or stereo, more than the 15 watts of lights, anchor light, compartment lights, -- well you get the picture.
