Lead acid battery are the most common form for solar battery storage currently on the market.
Battle-tested, thousands of the world's people have used large of lead-acid batteries with solar electricity to remove their need to be
connected to the traditional electricity grid.
The most common setup of lead acid batteries you'll see is usually some kind of rural household installing a bank of batteries + solar panels,
because it's cheaper than paying $30,000 to get the grid extended all the way to their house.
However, some people who have normal access to the grid still elect to go off-grid with a big bank of lead acid batteries.

>FAQ
Q1.What is your warranty time for VRLA battery ?
A1: It depends on battery capacity, depth of discharge, and battery usage. Please kindly contact us for accurate information based on detailed requirements.
Q2. Why battery has different capacity at different hour rate?
A2: The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current.
For example, a battery that is discharged at 10A will give you more capacity than a battery that is discharged at 100A.
With the 20-hr rate, the battery is able to deliver more Ahs than with the 2-hr rate because the 20-hr rate uses a lower discharge current than the 2-hr rate.
Q3. Are you a battery manufacturer, and do you produce the plate by yourself ?
A3: Yes, we are a professional battery manufacture in Fujian Province, China. And we produce plates by ourselves.
Q4. How to proceed with an order?
A4. Firstly let us know your requirements or application. Secondly, We quote according to your requirements or our suggestions.
Thirdly customer confirms the samples and places a deposit for formal order.
Fourthly We arrange the production.
Q5: How about the delivery time?
A5: About 7 days for stock products, around 20 days for half container products, 30 days for 20ft full container products.
