Sulphated batteries

I have read where sulphated batteries can sometimes be reclaimed with a battery reconditioning phase that some battery chargers, such as mine, have. But would such a reconditioned battery be reliable? Is it likely to have lost much of its longevity? How would I know?

Drynoc, unless you are planning on some serious cruising, do yourself a favor. Go down to your local WallyWorld and get some new RV/Marine deep-cycle batteries. They''ll last 2-3 years then you buy new ones.

I have had gells, standard lead/acid, no-maintenance, and in my work, used the glassmat batteries. They all fail eventually. I have had customers put in 300-400 dollar batteries and then replace them in 3 years. It is all related to shock loads and charge cycles. If you are not going to be doing extended sailing, why would you need a battery that is rated in the thousands of cycles?

I hate to see you throwing your $$$ away. Even Cheepo batteries will last more than 2 or 3 years if you care for them properly. Keep an eye on them, if flood make sure water levels are proper. Make sure they are more or less level in the locker. Even "no-maintanance" batteries are in need of care most of them are still flood type. Other batteries are alot more $$$. Oh and a good quility 3-4 stage battery charger is a must.

If batteries are only lasting two to three years they are being abused. I would guess they are being too deeply discharged or being improperly recharged or both.

I guess I didn''t make myself clear. The batteries are only a little over a year old, but they have hardly been used due to engine failure. They have been in my basement all winter, unfortunately without being charged. My charger tells me they are sulphated, and I am wondering if they can be restored to usefulness, or should I buy new ones.

At this point you have nothing to loose by dropping a heavy charge, caps off, say 50 amps at 14.2 volts or slightly above on them for an hour or so. Then drop back to a normal charge overnight. They either will or will not come back. Let sit a few hours then test the cells with a hydrometer, not one of the colored bozo ball variety, but one that has a graduated float and is tempature compensated, about $15 at a good auto store. You may just get lucky.

The "basement" comment concerns me. I left two batteries on a concrete floor one winter and they were toast in the Spring. If yours were unprotected on concrete just go buy some new ones.
