Lead-acid battery charger

Mr Taz,

1). Use a well-regulated constant-voltage power supply that puts out 12.9V to 13.1V as a "float charger". Such a supply should by design be "current-limited" to between 0.5A to 2A, so that if connected to a mostly discharged battery, it doesn't catch fire You can build your own with an AC powered wall-wart that puts out ~15V DC, followed by an IC regulator like an LM317. Such a "float charger" can be left connected 24-7. I get five years or more of service from float-charged batteries.

A long-term "float-charged" battery will benefit from a once-per-month "equalization charge", for which you need a separate constant-current supply (I use a lab supply which has built-in electronic current limiting). Google "equalization charge".

I haven't seen this particular "technology" or read up on it, but my understanding is the same as yours. I have never heard of any "pulser" that magically resonates with sulfates and destroys them.

It sounds like a scam to me, but I would like to read test data if there is any from an independent testing facility showing that it actually works. I tend to be pretty cynical because of all the scams related to battery charging I have seen over the years (like rechargeable alkalines a while back).
