Is the charger "smart", or do you have to be careful to not overcharge the battery?

The instructions say keep batterie charging between mowings so I guess its smart.Ive used it about a month and I still have the same power

Hi, The manufacturer does not specify that it is a smart charger. This indicates that you may have to make sure that the battery does not get overcharged. In any case it is never a good practice to leave a battery in the charger longer than necessary. The good side of the neat lawn mower is that it does not need to be charged long to attain max power. I hope this information helps.

No it is not a smart charger. It will not overcharge your battery enough to destroy/damage it.

It will not overcharge, but I have felt for decades that rechargable batteries last longer if allowed to cycle through some discharge and then recharge. The Dorcy will get warm when plugged in and my fear of a fire, if unattended, is large.

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.

While technically any battery could leak I have never had this happen to these high quality "eneloop" batteries. Keep in mind it is not so much the battery being left in the device as it is where the device itself is left dormant. If there are frequent temperature and humidity changes the device terminals are likely to corrode which could then damage the battery. As with even mechanical devices (such as springs) it is cycling count that eventually takes its toll. There is a lot of technical data available on long term storage and recharging. From what I know you want to allow them to store partially drained, but NOT "dead" as you can get polarity reversals. Also, it is worth the investment on a "smart charger" that will not overheat the battery and will automatically put the battery through beneficial "cycles" to improve performance and life. Also, it is worth monitoring voltages on all your good batteries... remember the pack is degraded by the weakest battery. In summary, store cool partially drained, smart-charge and never let them overheat.

Yes, it does prevent over-charging. This is accomplished by the charger switching to a type of stand-by mode when the battery is fully charged. Its LED display shows the specific cycle in which the charger is operating. If the battery power drops to a level below full charge, the charger switches to charging mode to top-off the battery again. I am completely sold on this CTEK Charger! Also, it CAN re-charge a supposedly "Dead" battery, if the battery is still capable of accepting a charge. This is achieved through its "de-sulfation" (altho this is not the correct term) process.

This charger does have an auto shut off feature that's suppose to shut off the charger to prevent overcharging. I haven't needed that feature, so I can't tell you how well it works, only that's it's available.

I am not sure about the charger, but I consider it a smart purchase. It lets you know that it is charging and when it has finished. Buy it and enjoy the service it will provide. With a 2 year warranty, how can you go wrong.

I tried this and it did not work. I'm not sure what "smart" charging means, but this device charged my phone for a while and then turned off (or the phone turned itself off). The result is that if I leave it connected, I end up with a discharged phone. Not good.

charge it to be safe,when you plug the charge in it will automatically start charging at a lower number and work its way up,you can tell how much of a charge it needs by how long it takes to get back to 100%,you cant over charge it so this wont hurt it,once your sure its 100% only charge it when it gets low,if its fully charged your just wasting electricity!!!!!

It does have an overcharge safety, but I'd never advise leaving these types of batteries in any charger for more time that it takes to charge them, let alone days or weeks. You're just asking for trouble in that scenario.

Yes it comes with a battery charger but, a smart charger that prevents overcharging would be a wise investment. (It is too easy to leave the battery charging too long.)

No problem whatsoever. Just make sure you have the leads connected to your battery before plugging the unit in. If you plug the unit in first and the leads accidentally touch together you will most likely destroy the charger. That's from personal experience.

As I understand from the instructions, you can leave the battery in the charger. It will not overcharge.

Yes...according to a Clarasonic representative it is similar to a toothbrush charger. The unit can remain in the charger and plugged in all the time. You can not overcharge it.

No, not recommended. If the required load to maintain the two batteries (assuming they are wired in parallel) is unbalanced, this can damage the charger. These are cheap chargers, save yourself some grief and buy two.

Using up to 400mAh (500mAh might be fine but the batteries will be a bit warmer) in a smart charger and usually i will refresh the batteries in a high drain device (or the device you plan on using them in). If the device is not a high drain device such as a USB battery pack or a Maglite flashlight (you'd have to monitor the flashlight to avoid over discharging) then using a smart charger with a discharge feature is the best way. You shouldn't need to cycle the batteries more than once (top off charge &gt; discharge &gt; full recharge), you could actually test the batteries and that would be good enough, i suggested the latter though because i don't want to waste cycles on a smart charger. One full discharge cycle upon purchase is necessary due to self discharge and most likely because the batteries are more than a few months old and then subsequent refreshing is only needed based on usage. The more you recharge them the more you refresh them, but is generally a good idea to regularly charge them if you are using them daily.
