12 V 3300 mAh Ni-MH replacement battery

The Estry CSD12 is a 12.0 V nickel-metal hydride pack rated at 3300 mAh and 39.6 Wh. It matches the original dimensions of 138.77 x 72.88 x 71.18 mm and weighs 858.0 g. The cell includes overcharge, over-discharge, over-voltage and short-circuit protection. It is certified to ISO 9001, RoHS, CE, UN 38.3 and MSDS.

Suitable applications and limits

This pack suits owners of equipment that specifies a CSD12 battery and requires a direct-fit 12 V Ni-MH replacement. It is not intended for devices that need a different voltage, chemistry or form factor, nor for users who require a higher capacity than 3300 mAh. Always verify the part number on the original battery before ordering.

Deciding specification

The critical figure is the 12.0 V 3300 mAh rating; the device must be designed for exactly this voltage and capacity. If the original calls for a different voltage or a substantially larger amp-hour value, this unit will not operate correctly.

Questions about this item

How do I install the Estry CSD12 battery and what step is often missed?

Insert the pack so the terminals align with the device contacts, then secure the latch; the step often missed is verifying the 12.0 V polarity matches the original before closing the compartment.

What maintenance or replacement will this 3300 mAh Ni-MH pack need later?

Recharge every few months during storage to avoid deep discharge, and replace the pack when runtime drops noticeably below the 39.6 Wh rating.

What limit appears first under sustained use of this 12.0 V battery?

Voltage sag under heavy load will trigger the protection circuit before the 3300 mAh capacity is fully used.
