Read evidence and context
Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Suggestion
After you "fully" charge it, check the SG with a floating ball tester.
Leading evidence: 'Check sg' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check sg' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I know.....I should have put on a battery tender last November but I didn't.
I put on a battery charger yesterday at 4pm on 2 amp trickle charge and now at 8am it is still only reading 50%.
Anyone with experience......should I be patient or should I up the amps on the charger?
Pete
thanks guys.
I think I'll give a try at a higher amperage charging rate for the next 6 to 8 hours and if still the same, then I'll get the new battery!
Pete
Just bear in mind that after a complete discharge like this, a car battery permanently loses capacity. You may be able to get it to where it looks fully charged, but it will never be the same.
Usually that's prety true, tho it does depend on how old, how many times, and for how long it it was dead. The older, more times, and long it is dead , the longer there was time for the sulfination to take place which is what kills capacity, CCA, and life. As dirt cheap as new batteries are, I wouldn't even fool with it, as a weak battery stresses the other parts of the charging system, and any of them are many times more expensive than a $60 battery from Autozone. Heck, Costco has the right size & amps, etc for less than $40!! After you "fully" charge it, check the SG with a floating ball tester. If still low, get rid of it.
Well I need a new battery. Made the same mistake moved during the winter and got lazy to connect by battery tender. thought I could just connect the tender for a few days and it will be fine. First crank, tough start, but did start. Drove the car around for about 15miles. Turned her off and tried to crank her up again, but no juice. urgh!!! Connected the battery tender and red light came on then finally after 1/2 hr blinking green light for about 3 hrs before I gave up. I was a bit confused though, because before first crank, the tender gave me a solid green?
As mentionned above, I put the charger to 6 amps and after almost 2 days it indicated full charge.
Took a specific gravity reading and it reads "good".
Cranking speed is fast but in any case she starts up very quickly anyway so there isn't much cranking effort needed.
So..so far so good.
If it deteriorates, I'll let you guys know!!
