Deep Cycle Battery Charging
I have a 12v 105 ah battery and the only charger I have is a 2/4/6 amp charger/maintainer. I've hear that charging this slow is bad and I've also heard charging too fast is bad. What's the truth?

For that size battery, 6 amp setting is fine.
If it is a charger/maintainer as you say, it should drop down to a trickle charge after the battery is full up.
Also, make sure that you check the fluid level each time that you charge the battery and keep the plates covered. - If you need to add water, use ONLY distilled water (go buy a jug at the grocery store to keep on hand!)and not sink or creek water!!
On the internet, EVERYONE is entitled to their opinion!

Never quick charge a deep cycle battery. Make sure you run the battery down to around 80% discharge for maxium life.
1.Recharge immediately after each use
2.Use battery charger matched to the battery's size
3.Do not overcharge; an automatic charger that turns off or on with a timer is your best bet
4.Always slow charge a deep cycle battery; never fast charge or boost charge it
5.A 10-12 hour charge with the appropriate charger at the correct amp rate will usually bring your battery to a full state of charge from a deep discharge

when a batt shows no charge at all you may have to reverse the leads for a few seconds it knocks off the build up on the plates inside the batt do this a few times then hook up correct pos to pos and neg to neg and charge at 6amphr do not put on fast charge the batt needs a deep soak charge then after its charged back up dis charge down and then recharge right away this will revive the batt

I'm curious as to how many seconds 5-10 -15??? How many times? fast or slow? (understand slow after you knock off build-up) and will it harm your charger? Thanks

I own two boats...both have Bass Pro 3 bank XPS onboard chargers that I leave on trickle pretty much 24/7 while storing....batteries going on 5/6 yrs in one boat and 4 years in the other.

10 to 15 sec you can also do this by switching from power start if you have it 75amps on batt charger do that 4 to 5 times to get the batt going

If you are in the market for a new charger, Walmart has a black and decker charger with a battery refurbish / desulfer mode ( ~70 bucks). I have had luck refurbishing 4/5 batteries that were sitting for a few years. They would not take a charge from a regular charger. It has paid for itself a few times.
