will i ruin the battery if i go below 50% usage the first time i use it? or how many times below 50% am i allowed before i ruin it?

The first time I allowed this battery to drop below 50% was after 1 year 4 months of ownership. And, now it wont charge to above 10 volts. So, yeah... I disagree based on long term use and experience with the product not just a generalized view based on manufacture information.

No, you will not ruin the battery by a DOD (depth of discharge) below 50% the first time, or every time for that matter. You WILL reduce the lifespan by repeatedly taking it below 50% but in essence, the deep cycle battery is made for repeated discharge cycles followed by charging either by way of solar panels or AC battery charger. Batteries will last longer if you can manage to limit the DOD to a range between 70%-80%, for example, at 50% DOD you may get 450 charging cycles before the battery is dead but at 80% DOD you may get as many as 1,200 charging cycles. So while the greater depth of discharge is within the capability of the deep cycle battery, it does have a negative effect on lifespan. What can really damage the battery in very short order is slow recharging or leaving the battery depleted for long periods after the 50% DOD. Also leaving or allowing the batteries to operate at higher temperatures than 80 degrees takes its toll, so quickly recharging the battery will have mitigating qualities which will help to preserve the integrity of the battery. Overcharging and undercharging can result in the battery shedding active material or the sulfation of the battery so in addition to quickly recharging the battery after a deep discharge, you need to protect the battery from overcharging. This can be done with a charge controller if you are using solar power to recharge the battery or in the event of AC recharging, typically battery chargers have systems in place to prevent overcharging built into the charging device. So, I hope I have answered your question adequately as I have much experience with deep cycle batteries because I use them in my stand alone solar power station and have burned out several batteries due to my ignorance and clumsiness. Deep cycle batteries are tougher than the typical automotive battery with thicker lead plates and I think a little more tolerance to overworking than a much lighter duty auto battery. P.

Hi, To answer your question about the life of the new battery I bought for my macbook, a lot depends on the use during the time it is using the battery. I left it unplugged last night for about 5 hours and was using it about an hour of that time and it was down to 50%. So it used 50% in 5 hours. I hope this helps. Anymore question let me know. Thanks

I let my laptop run on battery and when it gets too low plug it back in. I have had this battery for about 6 months and have had no problems. My last battery gave out because I kept it plugged in all the time.

I've owned mine for almost a month and use it every week. I always leave 1 of my 2 batteries in the charger between uses so that I always have a fully charged battery. The instruction manual says that's fine and so far, I have not seen any issues with doing so.

I don't usually let the battery below 20%. One thing I have learned is that some chargers will burn out a battery if left plugged in continuously. Unplug when charged.

I never tried to go 50 hours as I usually recharge when it is down to one light (out of three when fully charged). I do usually go a few weeks of intermittent use before recharging. Battery life is not a problem. Do not lose your charger; they are hard to find and a replacement costs $40.

I have noticed that if the battery is not used, it is good for the time stated. Of course, any use or over charging will void the life of the battery. Just make sure if the battery is NOT used it is as good as new.

I take high resolution photos so battery life is shorter than it would be with lower. Right now it is 1/4 used up and has 109 minutes on it. I plan to buy a spare battery and keep one charged all the time.

1. You should use a charge controller to reduce risk of damage to the battery. 2. probably 3.3 amps but no way to be sure without seeing the label or cell spec

Brand new with average use it will last more than 20 hours. Do not make the mistake of overcharging the battery. Disconnect right after it is fully charged. The battery will start dying faster which happened to me.

Michelle, if you've Beene using it a lot the battery will slowing lose its power. Your best bet would be to move up to a LiPo battery.

Best to turn it off then charge it....don't let battery drain totally. I often use it plugged in when it's fully charged.

I haven't used it till the battery runs down in one sitting. I use it for 30 to 45 min at a time several times before having to recharge. We mainly use it while in the tanning bed. Usually only have to charge a couple of times a month.

When I ordered this product, it contained instructions for how to properly charge the battery for the first time. If I recall correctly, they recommended a full charge to 100% before use, and then unplugging the laptop and letting the battery drain all the way to 0%. Beyond that I don't remember any other tips. However here's a website that provides additional suggestions. The main point is NOT to keep your battery running at 100% AND plugged in at all times.https://www.luculentsystems.com/techblog/how-to-extend-laptops-battery-life-span/

I did not. Charged it fully and then used it till less than 7%. I'm averaging 4 days of usage... a mild user (wifi & bluetooth off). Bought a second battery so that I can charge one while the other is being used.

Thanks for your inquiry. All batteries are only charged with 50%-70% capacity when we shipped it out in order to avoid any dangerous occurrence happen. Usually, please don't use it up when you first install it and please kindly try to charge it around 12 hours at the first time, and then discharge it. Please do this cycle for 3-5 times continuously. This will help to activate the battery.

I've never let mine get completely down to 0%, the lowest I let it get down to is 20%, but so far on an average charge, is usually 6-7 hours. These are larger batteries than most so will take longer to charge.
