Any reason why you can't use a longer lasting lithium 9v battery instead of alkaline as instructed in manual?

You could use a Lith battery. When you get the unit test it immediately. The unit I received had a defective manual function.

Thanks Roy and John. I will use an alkaline battery. GalconUSA has been great to work with and Mr. Levinson and his team are what I wish all companies had representing them. Professional, courteous and so helpful. If Amazon does send you one that has 1401 marked inside the battery compartment then GalconUSA will make it right from my experience. This timer will do everything I need for my drip irrigation. Love the way it can be programmed for any day of the week as well as up to 4 different times a day that you select. Will also be connecting a rain sensor (closed type). Roy helped me verify that too. Customer service is 5 Stars! Thanks Roy and John. I will use an alkaline battery.

The controller will not be able to detect Low Voltage from a Lithium battery, it is not recommended. There was an issue with this controller, but limited to date code 1401. The date code is found under the battery compartment cover, etched into the plastic. If your unit has this date code, Galcon offers a replacement.

I haven't tried a lithium battery, but use the top of the line Duracell. I've had it in my timer for three years and it's still working great.

It doesn't matter that much, lithium ion batteries always have a controller, anything else would be dangerous, it shouldn't be more than an hour or a few more, in any case theres no risk of damaging it from "overcharging".

Mine works with regular alkaline batteries. Sounds like a defective unit, not a battery problem.

My battery still works the same as new. Lithium Ion batteries like to be stored with at least 3/4 charge and normally have very long life. Avoiding deep discharge should also prolong life. There are several good battery encyclopedias on the web that will tell you all about lithium ion batteries.

Another reason not to use rechargeables is that they can drain while idle more quickly than alkaline batteries. I wouldn't use them if you will be gone more than a couple of days.

2 wonderfully inexpensive totally common AA batteries available almost anywhere! Like to pay a bit more? Go alkaline or lithium AA for longer lasting. They are also easy to change!

Yes, I used alkaline when I received the radio because the rechargeable battery was low when I opened the box. I would not put the radio on the charging stand with alkaline batteries.

Apparently I have the "old" version (D cell batteries) but I've had the unit for several years and they've been no problem. I'd guess that they're using more solid state components and so are requiring less power -- thus the smaller batteries. In any case the system works, and works well. I wouldn't sweat the small stuff. PS - Also have the HWH system and have the same experience with it.

No alkaline can not be used , as for the 26650 rechargeable batteries it takes 2 or three with the extended piece which only extends time of usage .although when used on the highest output it will only last for about 45 minutes before it shuts off to not over heat the circuit then you must let it cool down and then it will work .

lithium and alkaline batteries are each suited for particular uses. Lithium batteries are more suited for heavy duty use. you might want to pose this question to the manufacturer on their website as to why this is a requirement.,

Hello there, you can try some alkaline, however I do believe there are rechargeable Lithium Ion batteries that will fit. They would be fairly expensive, but they would last a long time. They would really pay for themselves, and would have a better charge life. Be careful which brands, there are tons of rip-off brands. Go with duracell, or another company that is well known.

2x AA/LRG Alkaline Batteries (Ni-MH and Lithium batteries can also be used)

As far as I know you must replace the batteries, not charge them. And it is poorly designed electrically/electronically to use any type of rechargeable battery. I know as I tired. It drains a rechargeable to darn quick. Alkaline are not much better, even though it was designed for those. I went back to using manual mechanical ones.

Alkaline batteries die quickly in the heat. The hotter it is, the longer it is hot, the faster they die. Try lithium batteries instead for hot climates.

I'm not sure, because i've only used alkaline batteries in mine so far. But, you might ask one of the other buyers that use their lanterns often if they tried it.

I don't know why not? I use lithium and regular batteries for my other devices without a problem as long as it is the same voltage and size. Good lite and powerful and long lasting on even a near dead battery. Finish wears off though.

It was confusing to me too, but somehow I figured it out. Maybe I asked DeWalt for help. I bought two of the DC9180 lithium-ion batteries. Lithium-ion seemed like the better choice for use in my DeWalt drill, my DeWalt vacuum (DC515), and my DeWalt battery charger (DC9320). Amazingly, the instruction manual for the drill does not say anything about the proper battery. But it does mention batteries in the section about product warranty. It says that there is two years's worth of free service on these battery packs: DC9071, DC9091, DC9096, DC9180, DC9280, and DC9360. On the drill itself there is no mention of batteries.
