I am looking for a battery that will last for more than 8 years to store energy from my solar panel.?
I use a solar panel as a renewable energy and generate power. Since the battery life is 3-4 years, I am looking for a battery which will have good performance life period for over 8 years. Can you recommend some batteries?

Look up Electroveya. They build batteries for laptops and are currently working on building an electric car. They might be able to help you.
Shares in the company are cheap, and will very likely make you a bit of cash in the future. Check out EFL on the TSX. Buy and hold.
Industrial deep cycle batteries should work correctly in that application. Electric Forklift batteries can last for 10 years or more. Deep cycle batteries have a different plate structure than automotive ones. They do not need to produce large amounts of of current in a short amount of time, but are made for a steady, known amperage. An important point is that one does not drain them past 1/2 their Ah (Ampere Hour ) capacity prior to recharging. Battery manufacturers have technical data that gives metrics on the Ah rating, reserve capacity, and # of cycles of recharging a battery will take,
There are some additional energy storage possibilities working towards being cost effective for off grid uses. In 1999, I obtained a device called an electric double layer capacitor, it looked very promising back in the day, and since 10 years has elapsed, I believe the cost of the devices are falling into the reach of many consumers. There are disposal issues for SOME double layer capacitor designs, whereas popular lead-acid batteries are not only very HEAVY in weight, they also have to be disposed of correctly, unlike the balance of double layer capacitors. According to one manufacturer (nesscap: http://www.nesscap.com/products_advantages.htm ), the double layer capacitor should last 25 times longer versus a battery (they don’t mention which kind of battery, though).
no way. they can last 8 years, but in order to do that you have to buy batteries 3 times as large as you need, then as they age, in 8 years they will hold the charge your panels put out.
Even the car batteries have system that only allow the battery to run from 30% capacity to 80% capacity in order to get longer life. The best bet is to use deep cycle batteries and dispose of after 3 to 4 years and replace. you buy two sets instead of buying a single set that is 3 times to big to begin with.
I don’t know who is giving all the thumbs-downs. The others that say lead-acid can last 10 years or more are right. The batteries must be properly maintained, and the less % of capacity you discharge them, the longer they’ll last. For example, if your bank is 10 kWh, and you only use 1 kWh a day, that will be a good long life. If your bank is 2 kWh, it won’t last very long with that kind of charge/discharge.
For cost reasons, lead-acid is really your only practical choice today.
