Good Rechargable Batteries
These rechargeable D Batteries are well worth the price. They charge real fast and hold their charge even when in storage. Would purchase again.

I got tired of buying D cell batteries.
You know you have first world problems when you're concern for the day is getting good enough batteries for the automatic opening garbage can. So when I tell you I put these in the garbage, that's a good thing. They work well and with a brief charge seem to last a long time opening my garbage can. Highly recommended.

Go for it
Hard to see yet other time, but they definitely doing the job. They are way lighter than the original one. From the use I have of them that's a plus.

EEMB D Batteries 1.5V Rechargeable D Batteries
Less than a year ago, I bought 2 packs of 8 D cells for my emergency lantern for if the power goes out. The batteries were all corroded in the package, AGAIN, so I looked for rechargeables and found these with built in USB chargers. My Dad would have loved these! They blink while charging and the LED's become solid when they're charged. They charge pretty quickly. I wanted to see how long the charge would last, so I put them in the lantern and turned it up all the way, which is seriously bright and when the power goes out, I only turn it up less than half way. Two hours later, the lantern was still just as bright and the batteries tested in the green. I read some reviews which said that the batteries emit signals which interfere with radios, so I put them into my short wave radio and it worked fine and I tried them on AM radio, which the slightest little thing will interfere with, and that also worked fine. These are ingenious.

Yes need a recharge.
This item was as advertised and it wasn't damaged when it arrived and worked well but the batteries are alittle lite for D size but okay.

False Advertising
These 4 batteries work 10% as long as ni cad D cell batteries. That's 2 hours before going dead. It says Long-lasting Lithium D Cell batteries. This is purely false advertising and wrong.

Be careful using these - there is no current limit.
These batteries can put out potentially dangerous amounts of current - I measured 4.5A with a terminal voltage of 1V which could melt wires and potentially start a fire. Otherwise, these mostly live up to expectations - I measured 3200mA/hr not the claimed 3700.

Life saver!
10/10 saved my life (and my bank account) during the newborn phase, since all my baby wanted was to be in her swing! 10/10 recommend to every parent, or just everyone in general, I will be going and buying multiple rechargeable batteries is all different types!

Le batterie si ricaricano in 1 ora e mezza circa se totalmente scariche. Le ho comprate per usarle con un gioco per bambini che notoriamente sono energivori e hanno avuto una buona tenuta. La ricarica si può effettuare contemporaneamente usando il cavetto in dotazione e si può usare anche un powerbank al posto della presa elettrica. Mentre le pile si caricano c'è un led verde lampeggiante che si spegne una volta che il processo è terminato. Consiglio questo acquisto.

Había una oferta por 4 pilas a unos 27€ y me pareció que a unos 7€ unidad merecía la pena. Lo primero que sorprende es que son muy ligeras. No vienen en un estuche ni nada, solo en una caja de carton. Tienen un led verde que parpadea mientras cargan y se pone fijo al completar la carga. Vienen las 4 pilas y un cable de 4 tomas para cargarlas. Este tipo de pilas no son más que una batería de litio dentro con un circuito cargador y un conversor de voltaje a la baja mas o menos efectivo. Este tipo de circuitos tienen un cierto consumo dado que monitorizan la batería de litio continuamente (lo cual es necesario). Esto descarga la batería si se deja largo tiempo sin usar, es normal, esta tecnología funciona así. Solo se podría mejorar si se incorporase en la propia pila un interruptor para desconectar totalmente el circuito conversor. Eso es lo que pretendo hacer cuando desmonte una de las pilas con cuidado (si no la destruyo en el proceso). La caida de voltaje que se produce de los 3.7v de la batería a los 1.5v de salida tiene un coste. Se pierde energía por el camino, por eso nunca durará tanto como una pila primaria en igualdad de condiciones. Aqui el único factor determinante es la potencia de la pila de litio que lleve dentro. Digamos que podríamos considerar a estas pilas pequeños powerbanks de 1.5v. De cualquier modo es lo esperado. Una bateria de litio con un BMS/cargador USB y un conversor tipo buck a 1.5v. Tienen protección contra cortocircuito así que no les pidáis corrientes muy altas, se desconectarán por seguridad y tendréis que ponerlas a cargar (aunque sea unos segundos) para reactivar el circuito. Seguro que te puedes fabricar tu mismo uno mejor y más barato, pero puede que no tan bonito y te llevará tiempo. 7€ por una unidad de este tipo es aceptable si sabes como usarlas y conoces sus particularidades. Solo me gustaría que llevaran dentro una batería de litio más potente, tengo la sensación de que había sitio dentro para poner una del doble de capacidad. En cualquier caso, buenas pilas a ese precio para lo que hay por ahi. Actualizacion: He desarmado una pila. Tienen una carcasa de plástico bastante robusto, están enfundadas en un papel metálico y contienen una pila de litio 18500 de unos 2000mah. El circuito es bastante simple, las soldaduras están bien y protegidas/aisladas. Es bastante segura. He tenido que destruir la carcasa de plástico para abrirla, lo cual ya esperaba. No hay problema, podré usar la pila 18500 para otras cosas y el conversor/cargador también. Pienso hacerme una pila gigante de 1.5v que dure siglos ;-)
