FAQ

1. What are the concerns when using JYC batteries in a parallel or a serial series? 

● Do not mix brands, models and date codes
● No separate discharge then charging in a serial configuration. 
●  Under parallel usage, pay close attention to the differences in voltage in each circuit. 
● If the difference in voltage in each circuit is too high, do not charge/discharge as parallel. 
● The environment of all circuits must be similar.

2. How can you check a battery’s performance? 
Different usage applications will use different methods for evaluating a battery’s performance. Using a 20 hour rate or the 10 hour rate, you can use 0.05CA or 0.1CA to discharge the battery until the battery reaches a terminal voltage of 10.25 volts. You can then calculate the amp hours to see if the battery fits the specifications or not. For a 5 minutes rate, such as the HC1221W, you can use a 21 watts/cell discharge till the terminal voltage reaches a terminal voltage of 9.6 volts and then measure the discharge time to see if it meets the final specifications or not.

3. How are batteries rated? 
Lead acid batteries are rated based on a capacity given in a defined time. There is not a set industry standard for how to rate a battery.

4. When should a deep-cycle battery be used? 
Deep-cycle batteries are used when 50% or more of the capacity is used per cycle. The most common use of deep-cycle batteries is in applications that require deep, repetitive drain, like powerful car audio systems, trolling motors, golf carts, electric wheelchairs, or RV house power sources. Public safety and high-performance vehicles are other applications that call for the special characteristics of deep-cycle batteries.

5. How long can a battery last? 
The service design life of a battery varies considerably with how it is used, how it is maintained and charged, temperature, among other factors.

6. What determines the life of a VRLA battery? 
Sealed lead acid battery life is determined by many factors. These include temperature, depth and rate of discharge, and the number of charges and discharges (called cycles).

7. How can I evaluate the health and charge state of a battery? 
Routine battery examinations divulge irregularities in the charging system as well as in the batteries. The principle method is to examine the electrochemistry of the battery through hydrometric electrolyte inspection. As previously discussed, this important examination cannot be accomplished with sealed absorption or gel batteries. Voltage readings alone require experience to interpret. Hydrometric readings will uncover early warnings of overcharging or over-discharging before batteries are damaged. The state-of-charge and reliability of a lead acid battery can best be determined by the specific gravity of the electrolyte measured directly with a common bulb-type hydrometer with a glass float. We do not recommend the ball float type hydrometer. Specific gravity is a unit of measurement for determining the sulfuric acid content of the electrolyte. The recommended fully charged specific gravity of marine batteries is 1.255 to 1.265 taken at 80 C More than .025 spread in readings between fully charged cells indicates that the battery may need an equalization charge. If this condition persists, the cell is failing and the battery should be replaced. Since water has a value of 1.000, electrolyte with a specific gravity of 1.260 means it is 1.260 times heavier than pure water while pure concentrated sulfuric acid has a specific gravity of 1.835. 

8. SLA, VLRA, AGM, Is There A Difference?

SLA (Sealed Lead Acid) and VRLA (Valve Regulated Lead Acid) are different acronyms for the same battery. This battery type has the following characteristics: Maintenance-free, leak-proof, position insensitive. Batteries of this kind have a safety vent valve to exhaust the gas in case of excessive internal pressure builds up. AGM (Absorbed Glass Mat) refers to a specific type of SLA/VRLA where the electrolyte is absorbed into separators between the plates consisting of sponge like fine glass fiber mats. SLA batteries are divided up into specific subsets of batteries.

9. AGM And Gel Cell Batteries Difference?

Both type of batteries are sealed, valve regulated batteries allowing them to be used in any position. The difference lies in the way the electrolyte is immobilized. In case of AGM (absorbed glass mat), the newer of the two technologies, the electrolyte is absorbed by the glass fiber separator who acts like a sponge. In a gel-type battery the liquid electrolyte turns into a gel right after the battery is filled. Gel batteries use a different type of separators which are not absorbent. Because of the design, gel cell batteries don't offer the same power capacity as do the same physical size AGM battery. For example, an AGM battery that is 12V 100AH, whereas, for example, a gel cell battery in the same size case would only be rated at 84AH.However, the Gel Cell excels in slow discharge rates and slightly higher operating temperatures. The internal design is otherwise similar.

10. How To Connect A Battery In Series And Parallel?

You can connect your SLA battery in series or parallel. Connecting your SLA batteries in series will generate a higher voltage. For example, connecting two

12 Volt batteries will give you an output of 24 Volts.Connecting your batteries in parallel will increase the capacity (Ah). 

11. How Do I Charge The SLA Battery?

Some machines systematically charge the SLA battery, for example some home alarm or backup systems. That means, you do not have to take the battery out and charge it on a battery tender.

If you do need to charge your SLA battery with a battery tender, selecting the correct battery charger will impact the performance and service life of a sealed lead acid (SLA) battery. As a general rule of thumb when selecting a charger for an SLA battery is to use one that is no more than 20% of the capacity rating of the battery (at a 20hr. rate).

Example; to charge a 12 volt / 7.5Ah battery select a charger with a maximum charge output of 1.5 Amps (7.5 x 0.20 = 1.5).

12. What is the reason for battery ballooning or badly deformed in shell?

It may be due to improper use of the battery induces the battery to overcharge or the battery went out of thermos control.

13. Why the open circuit voltage or floating charge of the battery is lower than the rated requirement?

This problem called Undercharge(Self-discharge big), there are three possible reasons. First, the battery storage environment is in high temperature; Second, long-term storage without regular replenishment; Third, the floating voltage setting is low and keep in long-term use.

14. Why the inside of the battery gives off irritating odors during the charging process or the open circuit voltage was significantly higher than the rated requirement after disconnecting the system for more than 24 hours?

Reasons: 1. The charging system is out of control or parameter setting error, causing the charging current to exceed the regulation value and the charging time is longer.  2. The ambient temperature is too high and there is no temperature compensation adjustment for charging voltage.

15. I Dropped The SLA Battery, What Do I Do?

Please use protective gear before handling the battery to avoid exposure to sulfuric acid. Use rubber or neoprene gloves, safety glasses, acid resistant boots, apron and clothing. Neutralize any spilled electrolyte or exposed battery parts with soda ash or sodium bicarbonate until fizzing stops. Place the broken battery in a heavy gauge plastic bag or other non-metallic container. Recycle the battery immediately. Do not store old lead acid batteries, especially lead acid batteries with a broken case.
