"Just as described."
batteries
"Great batteries, wonderful customer service. The techs here are the best"
Authentic and fast shipping
"Good authentic product with fast shipping! Thank you"
Great Replacement Cell
"I purchased this battery to replace 'no-brand name' battery with no markings. It is performing very well. The device is a 'dusk to dawn' outdoor solar light. And with this battery, the light stays on throughout the night, then turns off at sunrise, ready for the next day."
works great
"works great and deliveryed faster then expected"
Replacement drill battery
"So far this battery is performing exactly like the factory battery"
They had my battery
"I looked all over the internet trying to find an obsolete battery and finally found it Battery Junction. It took no time to receive the battery as they stated when I placed my order. Soldiered metal tabs onto the new purchase and reassembled and worked and charged perfectly. Thanks!"
Almost what I ordered
"While these did much better than a previous purchase from another vendor of cells that were supposed to be 9000 mAh (silly me!), they are not 2500 mAh as advertised. I tested each of the dozen I ordered, and they came in at 2253 to 2313 mAh, with an average of 2282 for the batch."
Q&A
- Can you wield tabs onto these batteries?
- Technically you should be able to solder tabs to the battery. Please note that working with lithium ion batteries can be dangerous when you are attempting to solder. You can also damage the batteries themselves. We would strongly recommend that you either find someone who knows how to solder these appropriately or be sure you do your research. We do carry one that already has tabs installed. It is the Tenergy-30005 - it might be safer to get one that already has the tabs.
- Will this battery replace a LGDAHD418650
- I really don't know. The information I see only provides us with the size. Not the mAh or the Ah - Here is a link to the LG batteries on our site. Perhaps this will help. https://www.batteryjunction.com/catalogsearch/result/?q=lg+18650
- Work with vape?
- We cannot answer as to whether this is a good choice for your vape. That would be a good question for the manufacturer of your vape.
- I need for a radio for Battery use the model DX-18650-1S-P Material ternary Lithium3.7 V 18650- 200mAH
- I do not know much about the battery you are trying to replace but this Samsung 25R is an unprotected battery with a high drain. Unless your device requires an unprotected high drain battery, then this might not be the best choice. For a radio, I would think a protected cell would be a better choice and I am unsure if a high drain battery would be a requirement for the radio. Perhaps the Tenergy 30016 - https://www.batteryjunction.com/batteries/shop-by-size/18650/tenergy-30016
- is this battery good for a solar light on a flag pole
- I would be hesitant to suggest an unprotected battery. I would suggest a protected 18650 - if the battery you removed is flat topped then I would stick with that but if it had a button top, I would get the same.
