I'm about to replace my leasure battery just w onderd what make and amp rating any help appreciated ..
We have found that a 105/110/115 amp hour leisure battery is more than enough to supply the needs of 2 operators. We only run 2 pumps atm so have a standard leisure battery.
If you have other additional power users such as electric reels and a diesel heater then you need a combo battery. It will be a class b battery with a cca value. Its half way between a leisure battery and a starter battery. Its not a perfect starter or leisure battery but it will supply the extra current demands of say an electric reel.
We recommend your battery is fully recharged with a proper leisure battery charger at least every second day in summer and every day in winter.
We have always had good service from Numax batteries. But they will not honour their warranty with window cleaning use. Most of the other battery manufacturers have the same clause in the warranty clauses. We are classed as battery abusers.
The other consideration is the size of your battery tray/holder if that applies. If you can only fit an 85amph battery then its no use ordering a bigger battery as it won't fit.
