Questions about this item

How do I insert the Estry 1800mAh 2.4V Ni-MH battery into my Rollei Prego 8330 and which way do the contacts face?

Open the battery compartment, align the pack so its terminals match the camera's contacts, then slide it in until it clicks; the pack only fits one way, so do not force it.

Will this 1800mAh Ni-MH pack need recalibration or a full discharge cycle to keep its 4.32Wh capacity accurate?

Ni-MH chemistry does not require calibration cycles; charge it normally and avoid leaving it fully discharged for long periods to preserve capacity.

At continuous use, does the 2.4V 1800mAh pack hit a voltage sag or thermal limit first?

Under sustained drain the voltage will sag toward the end of charge before the pack reaches any thermal limit.
