It slides into the existing battery compartment and charges on the standard base station or desk charger already on the desk. No firmware update or configuration change is needed.

Questions about this item

How long will the 830 mAh 3.7 V cell keep a handset running before it needs recharging?

The 3.07 Wh lithium-ion pack supplies up to 0.83 Ah at 3.7 V, matching the original Siemens SL400 and SL780 series capacity for typical daily talk and standby time.

Does the battery heat up or draw extra current during continuous calls?

The 52.95 × 35.10 × 4.50 mm Li-ion cell operates within standard temperature limits for DECT handsets and does not increase handset warmth or power draw compared with the V30145-K1310-X444 original.

Which Siemens or Unify handsets must I already own for this pack to fit and connect?

It replaces the V30145-K1310-X444 and X445 cells in Gigaset SL400, SL400A, SL400H, SL610H, SL750, SL750H, SL78, SL780, SL785, SL788, SL78H, X656, OpenScape SL5, OpenStage SL4 and SL4 Professional models.
