Customer Ratings & Reviews

These batteries last the longest compared to other brands I have used. I am a medical/microbiology student and I use these batteries in my Bamboo pen for taking notes on my computer. If it gives you any idea of the quality of these batteries, I use my computer for taking notes daily which equates to at least 8+ hours of note-taking.

Finally found these batteries at Best Buy for my stylus. Exactly what I what was looking for and at a good price too.

My son recently got a drawing pad and bamboo pen for his animation class. The bamboo pen is great and holds a charge for several weeks of long use. However, it requires QUAD A batteries. Best But was the only place locally that carried them. It would be great to offer these at check out for people buying the Bamboo pen.

No issues. Fits in device well. Long life and works as expected.

Purchased these when my Surface Pro Pen stopped working. Made the replacement and my pen now works like a charm. I have to admit that at first I thought the pen was faulty. LOL! These batteries brought the life back to me pen. Thank you Best Buy, you always deliver!

These last a long time, I didn't have to replace my old ones for nearly 3 years. I use them in my Surface stylus, but they're not an easy battery to find. Luckily Best Buy carries them!

Only place in town that had these. Thank you for stocking this item.

I had no idea that the touch pen I had for Surface Pro needed a battery. It had stopped working few days back. After going thru the document saw that it needed "AAAA" batteries. Searched at Walmart & Target as usual. Then suddenly realized that BestBuy may have this and ordered this online. The touch pen works perfect now.

I purchased these to replace the battery in my active stylus that came with my Acer Switch 12 Alpha, replaced the original battery and been going strong since, haven't even needed to use the second battery that came in the pack and probably wont have to for several months maybe a year inside a stylus.

Just the size I needed. Ran great, would recommend again.

I bought the batteries for my Samsing pen. The service was great and extremely helpful in finding these small batteries.

These are batteries. AAAA, which isn't a common size, but they work very similar to other batteries. Energizer is a great brand and these batteries work exactly as advertised. I use them for my HP stylus I use with my Surface Pro. Great product.

LOL Not much to say or review here. They work as they're supposed to. I will say that these are not easy to find as they are more rare I suppose. I have one of those pen lights that I use in my studio and AAAA are required - so hats off to Best Buy for carrying them.

The purchase experience was pleasant. Staff was courteous and helpful. Product has exceeded my expectations.

Of course I like Energizer batteries because they don't leak ....but this size was hard to find went to 4 stories and then thought...Best Buy... and there they were!!! Glad they carry od sizes

Needed a 4A battery for my Surface PRO 3 pen and looked at the battery store, plus a number of other places that normally carry batteries, all to no avail until I stopped by BestBuy. They had the battery and a kind sales person took me directly to the spot where they were. My SP3 pen now works great again.

What else can you say about energizer batteries? They last long however, due to the rarity of the item I feel they were a bit overpriced. Maybe that's the legitimate price, I am not sure, but AAAA batteries are kind of hard to find.

Did not know these type of batteries existed. Purchased a stylus and it required 4A batteries. Located them at Best Buy for a good price. Batteries work fine.

Works good. Needed for my surface pro pen and is a rare battery

These are a unique battery that is hard to find but Best Buy had it.
