What has Trojan done ?

If you don't mind my asking? How do you know the chemistry has not changed?

OMG this is terrifying. I thought Trojan wanted 14-4-14.8 all along. What to do. I need to buy all new batteries now?

Rolls and Surrette has a fine PDF manual to download. It applies to Trojan 101% and the Space Cadet academy in Corona and to LTH and Johnson Controls 5% antimony batteries. Deviate from that charging protocol at your battery's risk. Try reconciling a correct charging protocol with "smart" converter's profiles.

The idiot who proclaimed bulk charging as being a stage hoped and prayed it would be taken as a charger controlled event. Two stage, three stage, twenty ninth stage. A charger takes x time to arrive at voltage limit. Factor 2 is how much time is spent at voltage limit before defaulting to float. I am one of the few who achieve instantaneous voltage limit because my chargers have capacity to do so.

It charges
Then hums
Then sepentines up and down
Then zots a higher voltage
Then sends Morse Code to the battery plates
Then falls to float

BUlk voltage is a screwy term, as during bulk, voltage eventually rises to absorption voltage. Technically bulk should end at absorption voltage.

IMO, 'bulk' should refer to initial amps applied to depleted battery

Trojan has been saying 14.8 absorption for a long time no?

I thought the 16.2 from 15.5 rise and 13.2 float to 13.5 was a more recent change.

I remember seeing rolls surrette user manual saying 16.2 fo EQ, and then seeing that trojan bumped their EQ voltage to this too, within the last 14 months or so.

And I am stuck with rote chemistry. My figures haven't changed in what - 10 years on this forum and 35 years overall. Chemistry like electricity is a discipline not a Madison Avenue playtoy.

just a guess, to many early deaths from consumer use
they finally published the real specs needed to keep them healthy
commercial users, using timed heavy duty chargers, not consumer 'smart' chargers
have been using the higher voltages for years
