Battery - where to buy?

[florence]

Hi

The battery on my 500 hasn't lasted well this time and the previous one from the same shop was faulty and so, consequently, I'm thinking of changing supplier.

Does anyone have a recommendation?

Thanks,

pay a bit more and go for a motobat, cheaper ones often fail within a few months.

I put a Motobatt on my CB 750 some 18 months ago, bought online from a company in Essex. Delivered the day after ordering and seems to work really well.

I've bought from this supplier with very good service so far,  same battery also from Amazon maybe better delivery cost depending on any concessions you get.

I'll not argue with the other options offerered above as I've not tried them, but I'm very impressed with these AGM Varta batteries both on cars and bikes. Any examples I've used or recommended to others show a remarkable ability to maintain voltage with no use and always start the engine when asked.

I have always used rob hunter lead acid batteries, never had any problems, I use an Optimate when laid up and check the charging system every few months, I usually get around 4 years out of them.

My Yuasa acid lead batteries were aways good for 6-7 years, be it that the last year it was sometimes kickstart only. I use a sophisticated multiphase charger but... only when needed. So I don't leave it connected all winter, but do a freshup charge say every 6 weeks. The advantage of AGM is maintenance free, the minus is you never know how old that battery is when you buy it and for what period of time it is already on way to it ends. The 'countdown' for a conventional lead acid battery does not begin before you actually have put in the acid. Personally I find AGM batteries overpriced, conventional batteries nowadays are competively priced.

Some of the agm batteries come with an acid pack so you start the lifespan when they arrive. I've had a lot of lead acid batteries from the local bike shop fail early, got a bit longer out of Yuasa and Varta, longer enough to justify the cost I would say. The odd thing is on my wifes cb250 the standard agm / mf battery only ever lasts a year, reagardless of use of the bike, using an optimate if not in use etc. My cb500 has made do with a car battery in the sidecar when it was last used, cheaper and longer lasting. The best battery I've encountered was a Numax gel battery from their industrial range. Arrived so flat that the terminals being shorted out on the frame of the machine wasnt causing sparks. It was quite old looking and second hand then, and has been in my ownership for 4 or 5 years now and still going strong starting a small diesel engine, or running a 12v winch. If Numax do a gold seal industrial one that will fit the cb500 I would really highly reccomend it. I'm lucky enough to be able to use bigger batteries on my 500/4.

Motobatt all the way.
If I could get one for my truck I would

As to where to buy from - these days they are readily posted and ebay or amazon are fine. I always check they send it pre filled or with an acid pack. All my batteries come off ebay - various sellers just check feedback a garuntee off an established seller is nice though I have yet to need to claim one.

thanks for all the replies, never heard of AGM batteries before, developed for stop/start cars it seems.

I suspect the agricultural supplier where I get my batteries has them on the shelf for too long.  I might try Amazon or something.

AGM is not a brand. It means absorbent glass mat.

My Optimate dried out my last lead acid battery completely. Have replaced all my batteries now with Motobatt AGM and thrown the Optimate in the bin. I replaced that with a Noco Genius that I only use once a month as the AGM's never appear to need topping up. The Noco is only on them for about 3 minutes. Top batteries. Also a great benefit in not having acid to leak on your frame and exhaust as the AGM's are sealed.
