If you have a calefon, then you need rechargeable “D” size batteries. Have you ever rummaged through drawers looking for regular “D” size batteries – only to find none? With CosasPrep’s rechargeable batteries, you may never need to buy (and throw away) another Alkaline battery again!
This is the only time we have put them on sale. Regularly $19.90 – Sale $14.90
Our batteries do not need a traditional battery charger, and they are 1.5 Volts, just like a regular alkaline battery. However, instead of discarding them when your water gets cold, you can plug them into a USB cable (supplied) and recharge them up to 1200 times. They come in 2-packs, so you can keep one charged and on standby, while using the other one.

Hurry – because we don’t have an infinite supply of lithium batteries, and restocking lithium products requires importing – which, even when possible, is extremely problematic.
Visit our easy-to-find store that is located just 5 blocks West of Parque Calderon on Simon Bolivar. We accept cash, credit cards, major crypto and PayPal.
P.S. Beef Jerky in vacuumed sealed bags is back. Great for any go-bag.
