## Overview

Panasonic’s Eneloop BQ-BS2E4SA C Size Battery Adapters let you convert AA Ni-MH rechargeable batteries into C size cells without sacrificing the original 2000mAh capacity or up to 2100 recharge cycles. Lightweight at 0.35 ounces each and designed with precision Japanese engineering, these adapters come in a convenient 4-pack, offering a sustainable, cost-effective solution for devices requiring C size batteries.

## Description

eneloop C size battery adapters are designed for use with eneloop AA rechargeable batteries. eneloop C and D size spacers allow for eneloop AA batteries to be inserted and utilized in C and D size battery applications. The battery cells maintain their original eneloop AA rechargeable battery performance characteristics including 2000mAh typical (1900 minimum), up to 2100 recharges, and will hold 70% of their charge for up to 10 years, (when not in use). These adapters are a great alternative when C and D size batteries are not available. Battery life will vary based on the application.

Review: Perfect compliment to the Eneloop AA battery family. - I bought these D Size Battery Spacers for use with my Eneloop AA batteries and these work great. I had previously bought a couple of lanterns and the one takes D batteries. I didn't mind that it took D batteries but the weight of 3 D batteries is more than 3 AA batteries and adds weight to an item that if you use it for camping you want to reduce the weight because you are carrying that item. Plus the D batteries I had originally installed were just throw away alkaline batteries. I always want to reduce waste so since I already had some AA Eneloop batteries, that I like a lot, I wanted to use them in my lantern and these spacers helped me do that. The lantern worked great with these batteries with no difference in function. They are so simple it amazes me that I had not used these before. The bottom unscrews and pops off and you just insert the AA Eneloop battery into the spacer correctly and seal it back up. They are now D cell sized but not D cell heavy plus when they run down I just have to recharge them. Now you can not recharge them within the D Cell spacers but they just unscrew and you take the AA battery out. I have not come across anything yet that will not run on the Eneloop AA battery inside or outside the D cell spacer but I rarely come across anything that uses D sized batteries. My Eneloop batteries are the Panasonic branded versions not the Sanyo so I can not comment on previous versions of Eneloop and the D sized spacers. So I would recommend these spacers for anyone who wants to reduce the weight of D cell battery operated devices as well as one who wants to reduce waste/cost of D cell batteries for those devices and also one who wants a rechargeable option that will last for years.
Review: Save money with these D battery adapters for your rechargeable AA - I love these adapters. I'm sold on my Eneloop AA and AAA batteries but from time to time I need a bigger sized and this fills that gap perfectly. Drop in a AA, power up your device. It works exactly as expected. I've used a previous set of these for years and it was time to add some more to the mix and I'm glad I did.

## Questions & Answers

**Q: how many AAs go into a C spacer?**
A: I have the D spacers and they use 1. I prefer the d rechargeables as the ones that use AA don't last long at all. I think they are a waste.I had both types in my fake candles, the spacer lasted 1 night and the others over a month. Very big difference. All were eneloop.

**Q: Do the C Spacer work with normal alkaline battery? I want to use this on a Nerf Rapidstrike**
A: The spacer has print that warns you not to use with non-Eneloop's. But I've used with Duracell ProCell successfully.  I wonder if using non-Eneloop batteries may damage the spacer over the long haul. Given these are high quality but really pricey ($5 for each spacer!!), I'm going to stick with using only Eneloop AA batteries in them, but yes you can potentially use any AA batteries but at your own risk.

**Q: How many "D" Size Spacers in an order? The picture shows four, right?**
A: It is for 4 spacers.  That is what I received with my order.

**Q: Anyone know if these fit the large maglite that use D cell batteries? Thanks in advance**
A: I have both a 2 cell and 3 cell Maglite flashlight for C sized batteries.  They are the LED version so they don't take as much energy as the incandescent bulbs.  I've used the eneloop C spacers in them for a few years and have been very happy with their performance.  They do not last as long for sure, but if you have another set charged and ready to go then simply swap out and go.  Way better than having to keep paying for C or D sized batteries that don't recharge or rechargeables that don't hold a charge.

### ⭐⭐⭐⭐⭐ Goodbye alkaline batteries!

These work well with the eneloop AA batteries & fit right in. They are good quality & the charge rate & battery life are what you can expect from the eneloop AA as that is what fits inside.
