Activating a dry AGM battery

Interesting certainly I remember the yuasa Micro something batteries I have in all my Aprilia motorsports equip . I believe come this way red writing on the battery case. Battery box comes with all liquid needed . You don't use any electrolyte that you have in the shop in the box with a dispenser tube and all that You use only what supplied with the battery I didn't know all the ins and outs of that but I know that's how they came and that's how you did it and that's what you used You don't add anything else water or any of it. But I don't think the larger car batteries came this way I could be wrong I have no idea but in my funny smaller powersports equipment this is how it's done or was done with this brand I don't see a lot of Yuasa or Deka items of this nature anymore.

 

In my youth (the Paleolithic era), We had an 18 Volt DC alarm system. I wanted to add a battery backup so I took an old 12v car battery (flooded dell) and found a free 6v battery at a junkyard. The 6v was dry so I washed out the crud in each cell and added fresh sulfuric acid. Surprisingly the battery came to life with an existing charge and in series with the 12v, provided backup power for many years.

Sure it does. IF you buy one "mail order".

Probably right about dealers and major battery retailers though.

 

Yup when I got a new AGM battery for my motorcycle it came with a bottle to fill it up.

 

^^ Walmart stores sold those "dry" AGM motorcycle batteries.
