Aim-TTi Battery Pack Replacement For PSA-T

In common with all equipment that uses high density rechargeable batteries, the battery life will deteriorate with use and over time. The figures quoted for typical battery operation time in the PSA-T series documentation apply to brand new batteries. When battery operation time deteriorates to a point where the user regards it as unacceptable, performance can be restored by replacing the batteries.

This battery pack is a complete assembly can and are suitable for both units (PSA1301 and PSA2701). These units use three NiMh AAA size batteries of 700mAh capacity.  These are tag ended and mounted onto a printed circuit board with a detachable connector.

Instructions for dismantling the unit and changing the battery assembly are included.

Alternatively, the individual batteries can be replaced by unsoldering them.  Replacements should have a capacity in the range 700mAh to 850mAh.  The higher capacity versions will give a slightly greater operating life but recharge time will be proportionally increased.

Note: that batteries with a capacity above 850mAh should not be used because the charge circuitry will turn off before full capacity has been reached.
