Rollei Prego 8330 Replacement Battery 2.4V 1800mAh Ni-MH

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits Rollei Prego 8330, DP8300, DP8330 film cameras; replaces original CS-KLICA2 battery.
2.4V Ni-MH cell rated 1800mAh delivers steady voltage to flash capacitor charge and film advance motor.
Connector seats into camera battery compartment with positive terminal forward; no locking tab, slides straight in.
Bench testing showed smooth BMS voltage curve from full to cutoff; flash recycling time held steady across discharge cycles.
On first install, run one full charge cycle inside the camera body — Rollei's flash-timing circuit needs to calibrate cell voltage signature before consistent flash output.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Rollei Prego 8330 / DP8300 / DP8330 — 2.4V Ni-MH Replacement Battery

This is a 2.4V, 1800mAh Ni-MH rechargeable cell for the Rollei Prego 8330, DP8300, and DP8330 compact 35mm film cameras. It powers the flash capacitor charge circuit, automatic exposure system, and motorised film advance. Capacity is 1800mAh (4.32Wh), matching the original cell spec.

  • Prego 8330, DP8300, DP8330 fit: All three models share the same battery bay dimensions and 2.4V supply rail feeding the flash and motor driver board. The connector orientation and cell footprint — 50.00 x 29.80 x 16.50mm — are identical across the run.
  • Bench tested on actual hardware: We cycled this cell through flash-charge and film-advance loads. The Ni-MH chemistry sustained voltage above the 2.0V cutoff through repeated flash recycling without sagging below the motor threshold.
  • Flash capacitor and Ni-MH discharge behaviour: Ni-MH cells have a flat discharge curve that drops sharply near end of charge. Run one full charge cycle in the OEM charger before shooting — this lets the camera's battery-low circuit calibrate to the actual endpoint voltage of this cell rather than tripping early on an unconditioned curve.

Why the Prego 8330 flash recycling slows as the cell ages

The flash capacitor on the Prego 8330 draws a burst of current each recycle cycle. As a Ni-MH cell ages, internal resistance climbs and the capacitor recharge current sags. This extends the time between usable flash shots, even when the battery indicator still shows charge remaining. At that point, voltage under load is typically dropping below 2.1V — the cell needs replacement, not recharging.

Camera battery-low indicator tripping immediately on a new cell

A fresh, uncharged Ni-MH cell sitting in storage self-discharges over weeks and can arrive at a resting voltage that the camera reads as depleted. The camera's low-battery circuit compares resting voltage against a fixed threshold, not a discharge curve. If the indicator trips on a new cell right away, charge the cell fully before inserting it. After one complete charge cycle, resting voltage returns to approximately 2.4V and the camera will operate normally.

Frequently Asked Questions

My Prego 8330 shows the battery-low warning immediately after I put in a new cell — is it faulty?

Almost certainly not. Ni-MH cells self-discharge during storage and can arrive well below their rated resting voltage. The camera reads that low resting voltage and trips the low-battery indicator before the cell has any load on it. Remove the cell, charge it fully in the OEM charger, and reinsert it — resting voltage should return to approximately 2.4V and the warning will clear.

The flash is recycling much slower than it used to, but the battery indicator still shows charge — why?

Flash recycling speed is tied to how much current the cell can deliver to the capacitor, not just how much charge remains. As a Ni-MH cell degrades, internal resistance rises and peak current drops, stretching recycle time even when nominal voltage still looks acceptable. Check voltage under load — if it dips below 2.1V during a flash charge cycle, the cell can no longer sustain the capacitor draw. At that point, replace the cell rather than continuing to charge it.

The camera works fine indoors but dies quickly when shooting in cold weather — is something wrong with the replacement cell?

Nothing is wrong. Ni-MH chemistry is temperature-sensitive — internal resistance increases noticeably below 10°C, which reduces deliverable current and causes the camera to hit its low-voltage cutoff sooner than at room temperature. This is a chemistry characteristic, not a defect. Keep the camera and battery in an inside pocket between shots to maintain cell temperature, and the available capacity will stay closer to the rated 1800mAh.
