Questions about this item

Does the 7.2 V 3700 mAh Ni-MH pack run hot or make noise when the Lyric panel is powered all day?

Ni-MH chemistry produces no audible noise and only slight warmth during continuous trickle charge; the pack has over-voltage and short-circuit protection to limit heat.

What existing hardware must I already have for this 100.8 × 68.0 × 17.2 mm battery to work?

You need a Lyric Control Panel LCP500-L or Lynx 5210 that accepts part numbers 300-03866, OSA214, LCP500-4B, LCP500-24B or LYNXRCHKIT-SHA.

Will this 26.64 Wh replacement behave the same as the original battery in my older LCP500-4B panel?

Yes — it matches the original 7.2 V 3700 mAh specification and fits the same compartment, so charge cycles and runtime remain identical.
