New Battery and Acid.

[jonno]

I have just received my new Yausa battery today and i would like to get this right as its my third battery in two years!!

The battery is supplied dry with a bottle of battery acid and instructions. The instructions recommend diluting the battery acid with distilled water to achieve a specific gravity!

Now, Im no chemist so could anyone instruct me on what to do (with due allowance for Health and Safety) in order to make this battery last a bit longer than the previous ones.

Thanks.

i thought batteries come with enough acid to fill em which mine did... as like ures so i just filled it up.. i know if ya ever need to top em up u use distilled or de-ironised water(water whats been boiled in kettle) ..steve

erm...............the correct way if its the same as ones i done.......

Invert onto battery top............smack it down so acid drains........leave for wotever time they say.............and give a FULL CHARGE!!!
Then fit ;D

I've just done a Yuasa battery for my LC.The no. was 12n5.5-3b and the instructions were fill to full line with acid,leave for an hour and top up if required with more acid.Charge for 24 hours and bobs yer uncle.Hope this helps.

Thats all you should have to do. Does the acid say what % it is

[jonno]

No, its just got a corrosive warning label on it with the number 8?

I can't believe we are still using these prehistoric batteries, don't they make a gel battery that fits
I use gel batteries on my deisel and both hybrids, far better and they pre filled, sealed & charged. It doesn't matter what angle they are fitted & you never have to top them up ;D

OK,

To wrap this up i bought a battery hydometer to test the strength of the acid supplied with the battery and found it to be correct. I emptied the acid solution into the battery cells equally but found it to be insufficient to bring all cells up to the higher level indicated on the battery case. (about 3 to 4 mm short on each cell). However upon charging the battery i noticed the level rise to the correct level so all is ok and as it should be.

Hope this helps other members.

trickle charge the battery,NOT on a high amp setting that you normally get on a car charger or you will shorten the life also batteries do not take well to being stored static when filled,if not using bike discharge with a 12v light and then trickle recharge this technique was used in subs to get the best out of the batteries,

Blimey it must have taken a long time to discharge a submerine's batteries with a 12v bulb

just bought a Evilbay battery, same method with the acids but I checked it with a multimeter hay presto....12.40 volt!!!
no charge needed?! straight to bike! as if by magic
chuffed at that ;D ;D
