I can't see why that would make it any better than any other starter battery tbh.

Yes it would last longer than a smaller starter battery because its has a bigger capacity.

There are numerous window cleaners who are quite happy with using starter batteries so I'm sure it will do a satisfactory job. Its just rather expensive when you consider the delivery charge as per Tayna website.

If you buy it on the internet, how will you get any action on the warranty if you need to?

The specs tell you it has good deep cycle capacity, but I can't see any figures to back it up.

Numax is starting to do dual purpose leisure batteries. Take for example the cxv31mf which is 110 amp and a CCA of 800. They say it is good for 500 cycles, but again they don't tell you what they specify as a deep cycle.

Over the years we have had good service from Numax batteries even although they refuse warranty on batteries used by window cleaners.

What ever battery you go for, these need to be fully recharged regularily. With your demands of pumps and electric reels at least every few days even if you have a scr and do a reasonable daily mileage.

It will be interesting to see how you get on with it in the future. I was tempted to go down a similar route last battery charge. I was looking at Banner batteries, but eventually opted for the safest route that I knew.

The problem we have as window cleaners is that our power demands are half way in between a leisure battery and a starter battery.

If you run a single powered hose reel your auxillary battery needs to be able to supple a current of about 25 amps, albeit for a short period of time. If both of you decide to reel your hoses in together there is 50 amps. Thats way ahead of what a leisure battery will provide without it being damaged.

Traction batteries (Trojan) are more what we want but they are heavy, expensive and as they are 6v we would need 2 of them to make 12v. But they are excellent dual purpose batteries.

We have to thank the caravan market now as caravan mowers are getting more popular and they draw current from the caravans leisure batteries. So its about time that we started to see dual purpose batteries on a bigger scale. So any leisure battery that also quotes a CCA value will be a dual purpose battery.
