  • Parts Online is a great source of Lifeline batteries
We purchased 4 of these 6V Lifeline batteries plus one group 31 12V Lifeline battery for our sailboat. We wired them to have a house bank of 440 AH 12 V and a separate starting bank with the group 31 (105 AH). They lasted for 6 years of fairly heavy use, even though we abused the starting battery by using it overnight a few times, running it down. These are the best deep cycle batteries we have found. We just ordered a full replacement set from Parts Online on Amazon, and we were amazed by the seller. The batteries arrived a day earlier than promised and the packaging was incredible. The batteries were in their factory boxes packed inside larger shipping boxes with at least two inches of rigid expanded foam. In short, if you are willing to pay the money for these batteries, ordering them on Amazon from Parts Online is great. ... show more

  • They were good for a whole week!
For me they are a mega giant disappointment. I bought four of these. The first week I had them, fully charged to 13.4v, I put a large load on them for about 20 minutes just to see what they could do. 2500w seems to have ruined them. Ever since then they won’t hold a charge over 12.7v and a 110w load drains them to around 11.5v in 10 hours. I was told, by a Lifeline tech, that my 400w of solar on the roof is half of what I need. Ok. So I took two of them out of circuit. Still won’t hold a charge. And the drain is the same. Lifeline informed me that ALL of their batteries are perfect, they DO NOT make mistakes and I’m doing something wrong. I’ve decided they’re right. What I’m doing wrong is using them. I never dreamed that a 100w load would be considered massive. Well, after a $1700.00 investment I get about the same service that I got from my 2 Walmart deep cycle flooded batteries. And no warranty!!!!! ... show more

  • Good value for the money
A very good product -the same kind of batteries lasted in my boat more than nine years.

  • These are milspec batteries that will work for any application and do it great.
I have had the lifeline batteries before in a 94 Boulder Motorhome. Those batteries were 12 years old when I sold unit and they were still working 100 percent. I installed six Lifeline 6volt batteries in our recently purchased 04 Winnebago Vectra and they are performing great. I try to go with what works the best and Lifeline is it. ... show more

  • Not for use on a live aboard boat or RV. Only good for temporary. Maybe 4 or 5 hours a day
Would not recommend for RV or boat. I have to have 2 fully charged or it won't even run my small refrigerator. Then you have to charge them fully without anything connected to them. Then you can't use them for at least 4 hours after they are charged. If you live on a boat or RV you need constant power. You can't use these batteries while you're charging them or for at least 4 hours after they are charged. Useless when you need them for power supply. Only good for temporary use. Pay the extra money and get real ones. The batteries I got from west marine ran my refrigerator and everything else for 3 days before I had to charge them back up. These batteries only run my refrigerator for about 3 hours. That's it! Ridiculous! Just remember, you have to fully charge these batteries with no load and then not use them for 4 hours after they are charged! They don't tell you that when you go to buy them! ... show more

  • VERY HAPPY WITH THESE BATTERIES
VERY HAPPY WITH THESE BATTERIES!!! I bought two of these batteries for my Class B motor home and power seems endless now. Great for boondocking. Wish I had gotten them sooner. Yes, they're expensive, but totally worth the investment.

  • Worth the money
Use two of these wired in parallel with a 300 watt solar system in our RV and the batteries work like a charm. Zero maintenance and the 220 amp hours means we never have to worry about running out of power.
