Questions about this item

How often will the 2500mAh Ni-MH pack need replacing under daily use?

The pack is rated for one year of service; actual lifespan depends on charge cycles and depth of discharge.

What stops the 7.2 V battery from running continuously in the magnifying glass?

Built-in protection cuts power on over-charge, over-discharge, over-voltage or short circuit, limiting uninterrupted run-time.

Does the 236.4 g pack get hot or noisy during all-day operation?

Ni-MH chemistry runs silently; warmth is normal under load but the protection circuit prevents excessive temperature rise.
