AGM 4ah 12 Volt Sealed Lead Acid Battery Backup Power 1.36kg

Small Size Maintenance Free Sealed Lead Acid Battery 12v 4ah For Backup Power

> Main Features

1. Low self discharge

The self –discharge rate for FOBERRIA Sealed Lead Acid Battery is about 2-3% per month at room .temperature compared with 20-30%

for other common battery systems.

2. Maintenance free sealed lead acid battery

As it is valve-regulated sealed lead acid battery.sealed and glass mat is used .acid is trapped inside. so refilling is not needed and is

leak proof.

3. No memory effect

Some Sealed Lead Acid batteries .say nickel –cadmium batteries will become conditioned to provide less power offer repetitious short

usage /discharge.

4. Longer service life

Used thick and massive calcium grate ensure that FOBERRIA battery has a longer service life over 10years.

5. High discharge rate

Since the internal resistance is low .the battery can provide high rate of discharge.

6. Wide operation temperature range

VRLA Sealed Lead Acid Battery capacity is rated at 25°C, and will operate from 15°C +50°C when it is fly charged Ambient temperature

is 25°C.Service life will be more efficient under 15’C to 25”C .

Q1: How to choose the right battery?

A1: Tell us your demand, then our sales will recommend a suitable battery for you.

Q2. Do you have any MOQ limit?

A2: Yes, we have MOQ for mass production, it depends on the different model numbers. 50-500pcs sample order is available.

for sample checking is available.

Q3. Is it OK to print my logo on the product?

A3: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.

Q4. Why battery has different capacity at different hour rate?

A4: 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.

Q5. Are you a battery manufacturer, and do you produce the plate by yourself ?

A5: Yes, we are a professional battery manufacture in Fujian Province, China. And we produce plates by ourselves.

Q6. How to proceed with an order?

A6. Firstly let us know your requirements or application. Secondly, We quote according to your requirements or our suggestions.
