30 minutes to an hour. Depending on which charger u have. Quick charger 30 minutes.

It can take between one and a half to two hours to charge the battery if charged when about 15% of the charge remains. I usually do not let mine completely run out but based on the time it takes for 85% of the battery to charge, I would estimate two hours and twenty minutes to two and a half hours for a full charge.

I can charge my radios from completely dead to fully charged in less than 8 hours. If you charge for over 24 hours and still can't get a full charge, either your battery pack needs to be replaced, or your charger is defective.

24 watt hour sounds like 1.5 amp hour. more information can be found here http://toolguyd.com/ryobi-18v-lithium-ion-batteries/

5 or 6 hours for a 100 Amphour battery or faster if you use the 120 AC to run a 15 - 20 amp battery charger which I prefer

Yes, you can. But you need to be aware of problems that may arise from overcharging your car battery. This is designed more for short term charging where you won't leave the panel/kit connected for more than 24 hours. Ideally one should not charge a battery for more than 12 hours. It is safe for a 10 amp charge for that time frame on vehicle batteries. Smaller batteries like atv or motorcycle batteries should get 2 amp for 1-2 hours. Make sure your water levels are up before charging. Also, if you are storing a battery for extended periods of time, charge it every 3 months. Once the charge is less than 12.6 on a 12 volt battery, they start to degrade. This reduces the life of the battery as well as the true cranking power. The safest bet for long-term charging is to use a charge controller which will monitor the voltage of the battery and maintain the proper levels. Something like this would work great: http://www.amazon.com/Brunton-Controller-12-Volt-Battery-Monitor/dp/B000P696QS

They recommend 12 hours for full charging time. The unit comes with (2) batteries, just FYI. I've trimmed my yard (3) times on one battery, which surprised me. I have yet to install the second battery.

It depends a lot on the project...7" screws into landscape timbers take it down a lot faster than 2" screws into decking. I also have an 18 volt Ryobi with Ni-cad batteries that I use and would say that, under most situations, the Hitachi 12 volt lith. does as much work as the Ryobi on a battery charge,,,sometimes it even lasts longer. I always have a second battery charges before I start any big projects.

With the stock battery around 12 minute's. .i bought a high performance battery as an extra and it runs almost 25 minutes. . Charging varies with battery size.. around an hour i think. You want to let a Lipo battery cool down before you charge it.

Yes, that's what it is made for. The controller will charge the battery until it gets to around 13.7vdc and then rest until the battery voltage falls to less than 12.7vdc and the charger will again start to charge the battery and so on. The fully charged voltage of most 12vdc batteries is 12.7vdc.

I think 1 yr. I bought one of these mowers for my daughter. Battery ended up being defective. She contacted Ryobi and they were very responsive. Shipped her another battery with no questions.

Both models are dual chemistry. Ryobi refers to the P117 model as a 30 minute "fast charge" charger. The P118 model is a "1 hour" charger. Having owned both, the P118 is a little slower but it will charge my P203 battery (high capacity) in about 40 minutes versus the P117 that charged in 25-30 minutes. That's fully depleted to fully charged.

Depends on how long you have had the battery and if you have damaged it or properly installed it when building your model. However I would recommend charging it for 30minutes if its low on charge and an 1 or more if you almost depleted it. However please charge the battery in a lipo lithium bag, because in some cases during charging if overcharged or any thing goes wrong within the battery cells the battery itself may overheat and catch fire. Please never charge it without supervision always monitor it and unplug it if not in use.

Sometimes it takes 12 hours, I bought 2 battery packs, They last me about a week of riding for about 40 minutes every morning before I have to change. I leave them plugged in to the light so there is always a bit of current draw even with the light off. I have ridden for > 3 hours on a charge and still used it the next day. I really like this unit even if it does take 12 hours to charge.

That depends on many factors such as age of battery, outside air temperature, and extra weight due to add-ons. In general, you can expect between 6 to 8 minutes. It's very important to notrun the battery down below 3.70/3.74 volts per cell.

Hello! I have several 18V Ryobi Lithium batteries. This is where I use the this charger. Works great! RCH

You need to buy a 12 regulator they sell for solar panels so it will not over charge your 12 volt batteries.
