Charging the Battery: Is this a so called "smart battery charger" that won't over-charge?

So do you have to plug in the entire mower? or can you take out the battery and just plug that in?

I use a computer controlled smart charger. There are lots of good options out there.

yes you must buy a type of charge controller that prevents your batteries from being over charged or over discharged. a pwm (pulse width modulation) is a good affordable choice for charge controllers. i think the one i bought was 60$

I am using a car battery charger bought at (B&D;) Walmart and it works fine. The battery charger need be "smart" enough to sense when the battery is full and automatically shut off. Overcharging a sealed lead acid battery would not be good.

Yes, I have charged two extra batteries to take on a trip with me and know if I'm out all day and night, I won't run out of charge. I also bought an Anker brand USB portable battery charger from Amazon for my Color Nook and Android phone (takes a while to charge either if they are really low). This travels in my purse and can be used on a long air flight!

I'd look in the manual for something saying "It will not overcharge if left plugged in". If you can't find such, then I'd plug it in and check the voltage on the battery every hour for 4-6 hours. If the voltage never goes above ~14.5V everything's fine, but if you see 15V or higher then you're "overcharging" and want to pull the plug.Another option to consider if you like the idea of keeping it "freshly charged" would be to put it on a timer that comes on for 15-30 minutes each day, but isn't on 24/7.

Yes. However, using a cheap charger, one that has a timer, can damage the batteries and they always cause them to not last nearly as long. A smart charger measures the voltage among other indicators, to determine when the battery is fully charged. There some really good and/or expensive smart chargers and I have tried a few. Two of my favorites are the Titanium Innovations MD-1600L and the La Crosse BC-500. Both come with a car cigarette plug so it can be used on the go. The MD-1600L also has two USB ports, so I can charge two phones and 16 AA or AAA batteries all at once. Both of these chargers allow you to charge 1 battery at a time or use every slot. I hope this helps someone. Yes. However, using a cheap charger, one that has a timer, can damage the batteries and they always cause them to not last nearly as long.

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry. I cannot answer that question.

Yes, You should put a charge controller in line to batteries, rated at the proper amps/watts so you don't overcharge batt.

No, it is not. But I found, after reading other comments, that this battery charger 'does' overload if you run it continually--charging four more batteries right after the first four have completed a charge. I had some of the same problems as the others, but after I tested an idea, I found that it's best to give the unit a few hours break after I've charged four batteries. Then you can start the unit again and it will charge perfectly.

No, the battery cannot be overcharged. But I would not leave it on 'charge' indefinitely.

Not that I have found. We keep ours plugged into the charger, just a blue light that it's charged and have not had a problem with over charging.

yes it will not overcharge, once it drops below full charge it brings it back up. I have three of these and always leave them in with no problems

I don't know about the overcharge issue as I have been charging mine by my chair as I'm watching TV. When all four lights quit blinking its done. I left my charger outside for most of the day, and it seemed to hardly charge at all. Don't count on it for a quick charge solution

yes I don't see why it would not work, you should use a charge controller to prevent overcharging

Lithium batteries cannot be overcharged - part of their design must include a charge controller for safety, so lithium battery chargers (cell phones, screwdrivers, shavers, etc. alike) will always shut off when completed. To know if it's done charging without an indicator, feel the wall-wart power supply - it'll be cool if it's done charging.

It is suppose to be a smart charger, that is, it is advertised that it will charge your battery and then shut off after a full charge. It also states that the indicator light will be RED for charging and then turn GREEN when done . The one I received will not change colors and according to Amazon's customer service it will not do so, even though some reviews state that it will. So is it a "smart charger" or not I don't know and apparently neither does customer service. Who wrote the reviews that said it does ?????? Your guess is as good as mine!! For 14 dollars if you need a charger it will work, but I suggest you use a time set for 8 hours since Amazon won't back it up!
