MAINTENANCE
Read all of SAFETY and this section before attempting any procedure. Pay particular attention to Notices, Cautions, Warnings and Dangers.
Leoch Deep Cycle LDC Series Maintenance-free Battery
1. Battery Storage
High temperatures or poor ventilation during storage and transport can lead to higher self-discharge rate, so keep the battery well
ventilated and keep it away from open flames, sparks, heat sources, organic solvents, etc.
When storing batteries, they should be removed from the charger or load and stored in a dry, cool environment.
As battery storage requires charge maintenance, it is recommended that batteries should not be stored for longer than the
following.
6 months below 25°C 3 months 25°C to 35°C 6 weeks above 35°C
If storage exceeds the above time, it should be charged and maintained.
If you are using a charger, the charger setting parameters should follow the charging curves 4.1 and 4.2 until the charger turns
green and then continue float charging for 2-4hrs
If you are using other charging devices, below three charging methods are available.
1)
Constant voltage 2.40-2.45V/cell charge 8-12hrs;
2)
Constant voltage 2.45-2.48V/cell charge 6-8hrs;
3)
Constant current 0.1C(A) Charge for 4-6hrs.
You can also measure open-circuit voltage of the storage battery to determine whether it needs to be charged for maintenance. If
open-circuit voltage drops below 2.12V/cell, it is recommended to charge for maintence.
First in first out management is required during battery storage to avoid battery performance degradation due to a long storage
period.
Failure to comply with these storage conditions may result in serious degradation of battery capacity and service life.

The battery can operate in above temperature
range, but the standard data is measured at 25°C. The ideal temperature range for charge and discharge is 20
~ 30°C for best battery performance and life. Use at lower temperatures will shorten discharge times, while use at higher
temperature will shorten life and increase potential for thermal runaway.
Batteries should be kept away from open flames, sparks and heat sources. Avoid heat and direct sun explosion.
Keep away from wet places that may be soaked in water.
The battery will release a small amount of gas in normal use, should avoided completely closed place.
Different specifications, different years, different brands, different performance of the battery cannot be mixed, if you need to mix,
please contact us for technical guidance.
Notice:
If there is an accidental overcharging, the gas inside the battery will be discharged from the safety valve. Contact the ground before
operation to release the static electricity that may exist on the body or clothing.
