These 10440 rechargeable lithium batteries will keep you from having to buy expensive lithium batteries over and over. Roughly the same size as AAA batteries, each 10440 is 3.6V and 500 mAh. No protection circuit is on these, so be very careful not to overcharge or over discharge these batteries. As with all lithium batteries, the proper care needs to be observed. Do not overheat, incinerate, reverse polarity, mix voltages, or do any other potentially dangerous activity with these or any other lithium batteries.
Please note that we cannot ship lithium batteries of any kind to an international address via USPS. International orders containing only lithium batteries will be canceled and refunded. International orders containing lithium batteries and other items will be held while we contact you for further information. Contact us if you would like a quote for DHL or another form of shipping, but be aware that the cost is much higher than via USPS.
