The instructions the manufacturers send can be sometimes confusing and incomplete, and if you talk to 10 people you will get 10 slightly different opinions...so I called one battery maker today for clarification and here is what the tech help person told me regarding placing one of their new 35A battery into service: I took notes, and then reviewed the steps with him.


Barely cover plates with electrolytes.
Wait 1/2hr.
Shake, vibrate battery to bump air bubbles off plates.
Re-cover plates if necessary with electrolyte.
If cool, charge; maximum 10A, 1hr. A higher charge rate here is better (up to 10A), as it warms the plates, making more bubbles come off.
Cool.
Fill to bottom of split ring with electrolyte, then charge @ 2A, overnight with 'trickle' charger, one that reduces output as goal is reached.

From now on, only use distilled water to replenish - throw away the acid.

If plates ever get dry during the battery's lifetime, charge 1hr THEN add H20(d), but only to 1/8" below split ring. Then finish charging. Something about the heat is necessary for a best return to service.


So I had always thought slow charge rates results in a longer battery life and;
I never would have dreamed of charging a battery with exposed plates. Chernobyl comes to mind.
