Any other suggestions?



Actually, cycling is what me and a fiend decided to do with his system
The details are lost now as this was the early 80's but, we designed a
switching circuit based on low voltage and temperature and, a series of
random cyclic charge and discharge.

We discharged into a heater blanket he made from fibred sheets which
encased the batter sides. No great heat was produced but, it did reduced
the bitter cold, some. I might add, this was occasional as, I am talking
North West England. Nothing as dire as some places.

Similarly, you could get a mains plug with inbuilt timers. Find a
circuit with a double poled relay switch which will either be charging
or discharging such that the battery is always cycling?


....Ray.
