I recently purchased 2 x Class 24 Lead Acid replacement batteries for my mobility scooter. the batteries claim they're 130 Ah, but the old ones, same size, were only 75 Ah.
I tried looking at who else makes these 130 Ah batteries, but now wonder how they shoe-horned an extra 30-45 Ah's into the same size format of the old batteries (Class 24).
The new batteries are also "Lead Acid", so I'm wondering if they are using a new chemical formulation for the electrolytes, different lead plates (if even lead?), or are they trying to "sell me a bill of sale"
I understand how AGM batteries can allow deeper discharge than Lead Acid, down to 20% DoC in some cases, but these are NOT AGM batteries.
I admit, they were cheap, and I understand I AM taking a chance on Wal-Mart branded batteries - EverStart Brand I believe.
I half expected to only get 100Ah of usable energy, which gives me almost double the range, but I'm still curious why 130 Ah. And, of course, HOW!
Is there something else going on in these batteries?
