What settings should I charge my battery?

[feignfeign]

I have this battery: AW IMR 18350 3.7v 800mAh

My charger gives me an option of 0.25A, 0.5A and 1.0A settings as well as an option between 3.2v, 3.6v and 3.8v.

xtar charger instruction sheets are badly translated. My gut feeling is to go 0.5A and 3.6V but just wanted to check with you guys

3.6, I use one amp charging because batteries are cheap. Maybe Mooch can chime in?

I don't know about your particular battery. What I believe is true generally is discharging and recharging are both stressful to a battery. Doing either one at a lower rate is easier on the battery than at a higher rate. Sometimes you might be in a hurry but I believe the battery would prefer to be recharged slowly.

The 0.25A setting will take longer but heat the battery less, so it should last longer. A 3.7V rating on a battery is the nominal rating. That is the range it will be in the longest in each duty cycle. You can charge it to the 3.8V setting, and check the actual battery voltage with a voltmeter when it finishes, most chargers will finish at 4.1-4.2V, which will quickly drop to the 3.7V nominal in usage..

Personally, for 18350 batteries, I wouldn't charge them any higher than the .5 setting. For any battery, if you have the time, slower is better. I even charge my 18650s at .25. But I have plenty of spares.

On your battery, I would stick to .5 amp max, as AM states: Standard Charge : CC/CV ( max. charging rate 0.8A )

Is the xtar a Vp2?
I've charged my cells at a 1/2 amp for a year. Now 1 amp the last 8 months. I've found no difference in performance or life of my batteries.
I only use 18650s..

yup its the vp2.

It sounds like the consensus is 3.6v at 1/2 amp. I will give that a try

Was thinking of buying another,,went to xtar site to look at new models. The descriptions are more clear.
Finally figured out how to use a charged cell to juice
up my phone.
I live in hurricane country..
I use 3.6 volts too. Great little charger..

I like my Xtar. I've had my VP1 for several years. It's only a 2 bay. But I usually have about 8 batteries in my rotation, so I've never felt I needed more bays.
