Default Battery life on Freego F2 and Leadway RM09D

Ive got a bunch of both models in stock and selling them gradually online.

They are chinese versions built on 3 X Lead Acid 12V batteries.

I retail the F2 for approx 3-3.5K and the Leadway for 3995.

I also own a battery reviver as with my stocks I need to re-activate the batteries prior to leaving my warehouse.

Basically I fix all the batteries when they are sold making sure they charge properly as a new unit should. With a 20AMP triple lead charger this is accomplished from completely dead overnight. Takes around 10 minutes to open
a unit completely and expose the battery terminals for a manual charge, and then another 10 minutes to re-attach all the terminal leads and put back together and test prior to leaving.

It actually only takes 2.5 months of non-use for a battery to require manual charging as the standard charger is only 1.6AMP.

My question is if anyone knows the basic life-span of the 12V batteries my projected time-frame for selling the remainder of my units is 12-36months as I sell only 1-4units/month and I still have 44 units in stock. That means I currently own 15 Freego F2 units and 29 Leadway RM09D.

Will I be ok using the battery reviver on each unit prior to each sale or will some of the batteries eventually become un-reviveable?

We will see. You may be right as have been having some trouble getting a new set of batteries revived.

The latest model Chinese Segway now has lithium ion with a claimed 45-50km
range and now all lead acid models have been discontinued.

I'm figuring there's a good reason lead acid models have been abolished and I'm
really hoping im not on the bad end of this stick, but we will see

As you might imagine ive now had some decent experience with Lead Acid batteries as I do all my own repair and maintenance myself.

Im convinced lead acid batteries sometimes "pretend" to be dead only to wake
up after repeated tampering or even if just given a break.

Once a brand new battery was indicated by the battery reviver all night as dead so I removed it and sat it up-right on the bench overnight. The next day tried the charger again and it started reviving fine.

Answer- My 20amp charger has trouble reviving 3 12V LA batteries from dead all at once. At this set-up each battery only has approx 6.65amps. When I do this each battery comes up as faulty. However when I put only two leads on at once each battery has 10Amps and seem to revive fine.

Thank you for the "good time" and it's very kind of you to let us learn the technical detail of the lead acid battery revival technique, you should publish a tutorial, I'm sure you will save a lot of substandard toy batteries and it also helps the environment as well.

You take me back to the memory lane, thank you.

Well it just shows at this point each battery needs somewhere between 6.65 and 10amps with 6.65 not being enough to revive properly.

Thats all it is as there is nothing wrong with the batteries!
