Dog won’t fully turnover

Get rid of the braille and put a Deka in it.
How olds the battery?
Not sure what hits/turns it means? Does the starter sound like it's spinning or sounds like it's getting held up?

Generally I try not to turn my K-9 completely over -- I like the rubber side down (shiny side up for the rest of you). 
Hey Mike, maybe he trying to teach an old Dog some new tricks?Generally I try not to turn my K-9 completely over -- I like the rubber side down (shiny side up for the rest of you).
There's a process charging a new [dry] battery. Yours is pre-filled and who knows if it was following hours to charge. Do you have a battery charger that is a touch over the amp hour rating of the battery?
You'd have to look at the charger's rating like seeing a number with decimal point like, 1.2a on the sticker on the back. That's too low if say the battery is a 14a hour? Then, you'd have to find a battery charger with say, 1.5a on the back of the sticker. And when you get the battery, literally charge it for 14 hours before installing it. Those batteries sit so you think 1% charge is in decline a day, then count two weeks sitting before shipped; it's 14% low or more.
So the deal is 'chemical reaction' is the acid separating from the water. Boil it back up and remix. Not [install] ride for a few hours, park it and let it sit how many weeks? 14% low is 'how many hours worth of recharge' is my new battery first time out?
See how long the [new] sitter had, waiting to be shipped? See how you just threw it in, rode too short a time charging it back up, and now it sits for a week or more? You've got nothing to lose you just charge it for well over the formula: 12 hours if it's rated at 12a. 14 hours or more is a battery being cooked at 1.5a is the charger. As if driving cross country, is the battery cooking along before you install it? I'd be cooking it for days on end like I do my 2013 battery. But I started with a dry battery and matched pre-service prep just what Yuasa told me they do with their competition's batteries.
Signed,
WATT did he say?

What is right? They replaced the battery. It’s an 18ah rated battery. The last one I charged at 5.5A over 3 1/2 hours. My charger can adjust and charge from below 1a to 8a, I can set a max time charged, but charger will cycle down and lower the amps as it gets closer to full charge. Thx

Lead acid batteries generally like to be charged at 10% of AH capacity, especially initialy which is exactly what Sven is saying.
Charge at 1.8A for 10hrs
Charge at 1.8A for 10hrs

Did you get a Braille again? If it reads 12.8 Vdc or above you should be good to go.

I thought self discharge was 1%/month not day -- reference https://batteryuniversity.com/learn/archive/can_the_lead_acid_battery_compete_in_modern_times
see mention of discharge under AGM.
Pg. 13: "At an average outdoor temperature of 77°F a leadantimony battery loses about half its capacity in only 12 days due to the combination of self-discharge and current drain. In another 12 days, it’s completely dead. In other words, it doesn’t take long for the double whammy of self-discharge/accessory drain to knock out a battery for good."

Ahh, ok -- AGM's self discharge is lower than a Leadantimony battery apparently. We weren't looking at same technology. Thanks for the reference.
