Valve regulated solar system AGM storage battery (12V70AH) dry battery ups power supply AGM deep cycle sealed lead acid battery --Sunstone manufacturer AGM Long life ML Series(12V70AH) Lead Acid battery Deep Cycle Lead Acid Battery UPS Battery Power Supply


SunStone Mainline (ML) series is designed for 10 years life.For this long life purpose, the plates are made by developed alloy which is more effectual for preventing corrosion. At the same time, we also according the percentage of alloy change the outlook and dimension of grid wire. It will give batteries more effective radius for chemical reaction. For this long life design life battery, new features include handles for easy lifting, copper terminals for higher current capacity and reduced damaged during transportation, designed to comply with EUROBAT (draft IEC 896-2), IEEE, JIS and BS 6290 Part4, using UL certified components.

Feature in details


Long life design


(ML) series of SunStone batteries are long life design batteries. Normally in
the alloy of plate, the percentage of Tin is 0.8%. For these batteries, we
double the percentage of Tin in the alloy. Also we change the percentage the
percentage of Ca in this alloy.

Valve Regulated Construction (Sealed)

Mainline (ML) series of SunStone batteries
are of the AGM (Absorbed Glass Mat) valve regulated (sealed) lead acid
rechargeable type. The electrolyte is suspended in a specially formulated non
woven glass mat separator. All the electrolyte is absorbed in this manner and
provides a safe non-spillable battery.


Gas Recombination System

The gasses generated in the normal
charge/discharge use of a rechargeable battery are internally recombined during
normal operating parameters. In the fact in normal operational use, more than
99% of the gasses generated are recombined.


Safety and Automatic Valve System

If the pressure is over 2-5 psi the safety valve will automatically open and
reseal. This promise that there is no any excessive accumulation if gas in the


Heavy Duty Grids

The grids are made by heavy duty lead calcium tin alloy. This provides: Safety
margin of performance condition, Excellent recovery capacity from deep
discharge, Extra service life in either cycle or float application, Low
self-discharge when it is not in working.

Float Service life of battery


Mainline (ML) series of SunStone batteries is
designed for float life of 10 years at 20°C(68°F).

Operation in any position

Because SunStone batteries are sealed and all
the acid is absorbed in the special separators, these batteries can be operated
in both vertical and horizontal position.

Wide Operation Temperature Range

SunStone batteries can be used in wide temperature range from -35°C to 45°C.

Available in flame retardant ABS material for the battery case V0

SunStone batteries cases can be make by flame retardant material V0. It depends on the
requirement of customer.





1. The battery is full of power when it’s out of factory, no need to use liquid charge;

2. no memory, no need to discharge battery use, suitable for circuit design;

3. by high partition, adsorption and strong;

4. there is no flowing liquid (poor liquid), does not leak acid and free Upside down,

5. comply with environmental requirements, ease of use,

6. the use of lead-calcium alloys, battery self-discharge is very low,

7. easy storage, less maintenance;

8. using ABS plastic shell and valve technology for safe use.







  1. Don’t near the hot source and don’t under the sunshine.
  2. Don’t charge in the sealed container.
  3. No short circuit. It should be addition charge if you don’t use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid corrosion.
  4. Don’t store in the space of acid gas.
  5. You should be careful and regular check when use the battery. To avoid the battery don’t work. You should change the battery if the capacity is not full or has been damage, especially after one year using.
  6. Don’t put the battery in the fire, or it will explode.
  7. Please use cotton cloth to clean, if the battery is broken down and leak electrolyte. Please wash your skin when touch the electrolyte.
  8. Don’t clean the battery by using the organic solution. (e.g. petrol)
