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
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.

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
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
A3: Yes, we are a professional battery manufacture in Fujian
Province, China. And we produce plates by ourselves.
