I purchased two domestic batteries from Baxters at Yardley Gobio Wharf, swapped the temporary start battery they had supplied earlier into a domestic so I had three identical domestic batteries. I then purchased a new 664 starter battery from Midland Chandlers. Like many boaters I contemplated upgrading the domestic battery technology but given the cost, options available and the charging system on Albert, I went for a like-for-like replacement.

Our truck-sized starter battery.
This left me with four dead 110 AH lead acid batteries. In the past I have taken the old batteries to the local tip, but this time I browsed the internet, talked to fellow moorers at the marina and decided a trip to a local scrap metal merchant in Bletchley was on the cards. The world of scrap metal is now very professional. I delivered the batteries to the yard; they weighed them and then directly transferred to my bank account around £40. It's well worth considering the local scrap dealer when disposing of old lead acid batteries, it goes someway towards defraying the cost of the new batteries.
