The Estry 151 replacement battery delivers 12.0V and 1800mAh for a total of 21.6Wh. It uses Ni-MH chemistry and matches the original VAC-905 part number. The pack measures 143.0 x 62.0 x 21.0mm and weighs 540.0g. It carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Compatibility and fit

This unit fits devices that require the 151 model or VAC-905 part number. Buyers with a different model number or part code cannot use this battery. Dimensions and connector layout are fixed, so equipment needing another form factor must look elsewhere.

Deciding specification

The critical figure is the 12.0V 1800mAh rating; the device must be designed for exactly that voltage and capacity. If the original equipment specifies a different voltage or capacity, this pack will not work.

Questions about this item

Will the 143.0 x 62.0 x 21.0 mm case fit the battery compartment of my 151 device?

The pack measures 143.0 x 62.0 x 21.0 mm and weighs 540.0 g; it is built to the exact dimensions of the original 151 battery so it seats correctly in the same cavity.

How do I replace the VAC-905 pack in the 151, and what step is often missed?

Open the compartment, unplug the old pack, connect the new 12.0 V 1800 mAh unit observing the keyed connector polarity, then close the latch — forgetting to seat the connector fully is the common mistake.

What ongoing care does the 21.6 Wh Ni-MH pack need to keep its capacity?

Store the pack at roughly half charge in a cool dry place, recharge it every few months during long storage, and avoid leaving it fully discharged or on continuous charge to preserve cycle life.
