Let me tell you about upper tier batteries. Rolls batteries on sailboat. Alternator install malfunction with L16 batteries. Explosion. Blew part of lid off one battery.

Refilled batteries. Used battery case epoxy to glue top of battery back on.

Rebuilt the alternator. Replaced regulator with un-garbage Ample Power unit. Then embarked on comprehensive battery CCA and amp hour tests. Ten batteries passed with flying colors.

Got an email from vessel owner. Aegean Sea. Six-months later. All working perfectly. Sent letter to one of my customers who passed it on to Rolls battery. Framed copy of correspondence mounted on CEO's office wall. This was 23 years ago. The work was performed 1,500 miles deep into Mexico.

SHOW ME proof of damage to battery performance.

Part of the reconditioning process involves venting of gas. Lifeline, braces those plates like they are part of an A-bomb shelter. THICK plates that are harder to break. The intercell connectors weigh four times as much as other AGM brands.

I have serious doubts that this battery has been significantly damaged.

Yes, banging and force-feeding has taken it's toll on ultimate lifespan potential. But a belly-ache after a gut-out is far from utter destruction.

Damaged? Please prove it. Baja racer subject their batteries to shocks that cause racer's kidneys to bleed for weeks afterwards. Batteries are good for season after season.

If interested, hook up a 50 watt light bulb for 24 hours. If glowing at 24 hours the capacity has not been significantly impaired. Yes the battery will be almost 100% depleted. Sue me. The test works and a single 90% discharge will not significantly affect lifespan.


Guesswork is cheap which means near worthless...
