New Yuasa batteries = junk!

[Paulus]

What is it with new Yuasa batteries? I just replaced mine at Xmas and the shop had to get 3 in before they found one that worked. Now it's 4 months old and going flat in a week! Boy do I feel stupid for not keeping the receipt. Yuasa used to be a pretty good brand but not anymore - my advice - steer clear of them. Anyone know of a good battery brand?

Gel or acid? Big difference in performance (and price! ) Have just bought a new Yuasa after my gel one packed up after 7 years.

Have a guess where Yuasa now source their battery's from?

And who always complains about the price,forcing them to lower costs...?

.... Boy do I feel stupid for not keeping the receipt....

Proof of purchase should be enough for any good shop, take along your bank statement and see if you can talk them into it.

A battery is not warrantied from date of sale,but date of activation.Any shop that deals with Yuasa can handle the claim....expect to be disapointed.

Don't know. It's a maintenance free YT12B-BS and it's junk already. Not happy!

i bought a new battery last year,old one stuffed as when alarm was turned on it wouldn't stop,only way was to turn alarm off at switch.got new battery and switched alarm on,worked fine as more charge in new battery,after about 5-6 months and little riding in winter the battery would loose charge quick,often needed jumper leads,took battery back to auto sparky,he recharged it and has been good since.even when bike not started for awhile,it still has heaps of charge now,mind you prior to giving it back the battery got pretty warm by positive terminal,fine since then though.

Hi

Firstly and this is important: Yuasa batteries are not all Japanese made -can be Taiwanese etc - which one was yours???
Yuasa Japan make high quality batteries - or they do normally do anyway.

Pointers to remember:

Fully charged battery is 12.6 volts.
Flat battery is 12.0 volts (or less) - often mistakes are made with this.

Batteries discharge normally when not in use.
Many m/cycles sit around through winter (part time M/cylists often get caught by this)
Depending on battery quality try 1% loss per day (alarms add to this of course)

Watch out for "trickle chargers" some will stuff your battery if you leave them attached for two long. Battery doc and Battery tender will not as they vary
the voltage and the current unlike the cheaper "repco" type etc.


Most bikes correct charging is 13.5-14.5 volts but you really want as close to 14.5 as possible. Gel batteries I'm told are damaged more easily by overchaging than conventional lead acid.

Motorcycle batteries get a hard life, watching all the people at the cold kiwi
pushing there bikes after the frost is always good viewing as long as it's not you pushing.

Remember having a stuffed battery will also tax your alternator and your starter motor somewhat.

Hope this helps and may save you money.

Well it was dead alright. They have warrantied it though so we'll see how the replacement holds up. I guess it can only be better!

Voltage regulators in bike often die with time. A symptom of this is that your bike will stuff batteries. I'd get the regulator checked it might not be the battery at all.

No, regulator output is fine. It is definitely the battery that was faulty.

and gel battries tend to last better when charged at 13.5-14v max.....unless your talking about AGM batrry's not GEL?
