How To Store HP ProBook 4421s Battery?
Keep HP ProBook 4421s battery in a cool and dry storage area. Refrigeration is recommended but freezers should be avoided. When refrigerated, the ProBook 4421s battery should be placed in a plastic bag to protect against condensation.
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). Lead-acid batteries must be stored fully charged.
Do not store lithium-ion fully depleted. If empty, charge for about 30 minutes before storage. Self-discharge on a depleted ProBook 4421s battery may cause the protection circuit to trip, preventing a recharge.
Do not stockpile li-ion batteries; avoid buying dated stock, even if offered at a reduced price. Observe the manufacturing date, if available.
Never leave a nickel-based battery sitting on a charger for more than a few days. Prolonged trickle charge causes crystalline formation (memory).
Always store a lead acid battery in full-charge condition. Observe the open terminal voltage and recharge the HP ProBook 4421s battery every 6 months or as recommended by the manufacturer. |
