How long should a battery last?

[syl]

How long should a battery last - plugged into an optimate when not being used over the winter.

Mine is dead again, only managed five and a half years.

I would say that 5 and a half years is a reasonable life to expect out of a battery.

I'd say normal is 3 to 5 years.

[Paddy Blake]

I have had a battery years but I have learned that a new battery may only last you days.

It is a bit like asking how long does a bulb last imo.

There is no answer.

I have never got 5 years out of a battery in daily use.
Maybe a bit over a year but that is going 8 hours a day 5 days a week and more.

[Kradmelder]

I find the original battery may last up to 5 years. After that about 3 years

I suppose it beat the last one (that wasn't plugged into an optimate when not in use) by over three years.

Gel or wet cell? Keeping the electrolyte levels topped up?

Mine is at least 5 years old.

[Kradmelder]

Im waiting for Teflonmike to make a post of battery capacity, amps, voltage, frequency of use, ambient temperature, lighting and accessories etc to calculate to the hour how long a battery will last

Before The Wall came down a Battery would easily last three to four years. But now with all these bludy Pols and Eastcranians flooding the country your luck if it stays on the bike while you're in buying a paper.

OEM Two-Three years.
After Market Four to five years. (Decent quality.)

£29.99 including delivery (YUASA YTX9-BS). Arrived this afternoon and just fitted. Of course, I now feel like a master mechanic - do my skills have no bounds?

Those boys at Yuasa also hold the record for the highest charge density you can get from lead-acid cells.

Prolly the reason why just about every maintained emergency light, UPS or other safety system uses them.

I would say 5 years is good going.

[TheSmiler]

I've had my motobatt for about 3 months, new regulator was fitted at the same time and now my indicators don't work when my headlight is on.

Also the neutral tell tale is going lighter so looks like I'll be getting a new battery if this carries on.

Anything over two years is good going.
