How to store JVC GR-D31US batteries?

Batteries are perishable products that start deteriorating right from the moment they leave the factory. There are simple preventive measures that JVC GR-D31US battery users can apply to slow the aging process. We provides guidelines to reduce age-related capacity losses and how to prime new and stored batteries:
1.Keep JVC GR-D31US batteries in a cool and dry storage area. Refrigeration is recommended but freezers should be avoided. When refrigerated, the battery should be placed in a plastic bag to protect against condensation.
2.Do not fully charge lithium and nickel-based batteries before storage. Keep them partially charged and apply a full charge before use. Store lithium-ion at about 40% state-of-charge (3.75-3.80V/cell open terminal).
3.Do not store lithium-ion fully depleted. If empty, charge for about 30 minutes before storage. Self-discharge on a depleted battery may cause the protection circuit to trip, preventing a recharge.
4.Do not stockpile lithium-ion batteries; avoid buying dated stock,Observe the manufacturing date, if available.

What every battery user should know?

1.How should I prepare my new JVC GR-D31US battery?
Batteries comes partially charged. You can use the Lithium-ion(Li-ion) battery right away and charge it when needed, But prime new Nickel-based battery by putting on a 14-16h charge.
2.Can I damage my JVC GR-D31US battery if incorrectly prepared?
No; Li-ion is forgiving to partial and full charge. No priming is needed when new.
3.Should I use up all JVC GR-D31US battery energy before charging?
No, it is better to recharge more often; avoid frequent full discharges. To maintain the optimum performance of JVC GR-D31US battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
4.Should I charge my battery partially or fully?
Full charge termination occurs by reading the voltage level and charge current. Fully charged a Li-ion battery is safe and does not cause harm. However, regarding the Nickel-based batteries, allow full charge without interruptions. Repeated partial charge can cause heat buildup. (Many chargers terminate charge by heat. A fully charged battery will re-heat, causing overcharge.)
5.Should I remove the JVC GR-D31US battery from the charger when full?
Yes, it is best to remove the pack from the charger when full. A prolonged trickle charge to a fully charged battery can be harmful.
6.Should the battery be kept charged when not in use?
Best to store at 40% charge or 3.75-3.80V/cell open terminal. Store in a cool, dry and clean place. Do not fully deplete battery because Li-ion may turn off its protection circuit. However,NiMH battery can be fully depleted and recharged. Priming may be needed.
7.What should I know about chargers?
Charger should apply full charge. Avoid economy chargers that advertise one-hours charge. Fastest full-charge time: 2-3 hours.
8.What are the allowable charging temperatures?
Rechargeable batteries can be used under a wide temperature range. Slow charge: 0°C - 45°C (32°F - 113°F) Fast charge: 5°C - 45°C (41°F - 113° F) Temperature sensor may prevent charge or cut off the charge prematurely. Charging a hot battery decreases the charge time. The battery may not fully charge.
