LR stands for round alkaline and CR for round lithium. The first letter indicates battery type, and the second letter indicates shape. So, R means round. 2. How Long Does an LR44 Battery Last? Battery is a 6 volt alkaline battery (non-rechargeable), which looks like a smaller version of a C cell battery. The 4LR44 Battery is most commonly used today in dog-collars. This battery goes by several other model numbers or names, such as: the PX28a, the A544, and the L1325.

The Duracell 76A is a direct replacement for the LR44, and the only difference between the two is the name. 5. Is LR44 better than SR44?This 6-volt alkaline battery is primarily used to power photo equipment, garage door opener, glucometers, and medical equipment. Also compatible with some electronic dog collars & invisible fence systems. It is well known that silver-oxide batteries have a steady discharge, and they are commonly employed in medical and precision instruments. Batteries like the SR44, SR44SW, 303, and 357 are all identical in size but differ in chemistry from the LR44. Rayverstar LR44/SR44SW supplies an excellent mixture of high energy and constant voltage. Zinc Air(PR44) Both the 357 and LR44 are silver oxide batteries. But 357 batteries last longer and maintain a more constant voltage than LR44 batteries. 4. What Duracell Replaces LR44? A544BP, 544A, V4032PX, L1325, 1414A, K28A, UL544A, BAT-001 Innotek, RFA-18, UL544A 6V, Innotek BAT-001, PX-28AB, A544, L1325 Dog, RFA18, 7H34, 4034PX, V34PX, This battery is used in the following devices:

However, before switching out SR44 batteries with LR44 or another type, be sure to read the equipment’s manual and comprehend its parameters. The Energizer batteries range also includes 2032, 2025 and 2016 batteries, so it’s easy to find reliable power in the size you need. For rechargeable batteries, search for Energizer Recharge – ideal for high-tech devices like laser pointers, remotes, keyless entry systems, watches and toys. Since creating the world’s original consumer battery in 1896, Energizer has led the charge in industry innovation with a proud history of firsts, including the world’s first on-battery tester. Silver-oxide batteries also have a higher nominal capacity, typically 150-200 mAh, and Low-drain batteries can claim to have more than 200 mAh of capacity. The self-discharge rate of the SR44 battery is extremely low, with most models having a shelf life of 5-7 years and some having a shelf life of 7-10 years.A cheaper alternative is to use 2pcs LR44 to replace the CR1/3N. But I would recommend using the CR/3N because it has the same chemistry as the CR123 and woudn't leak like the LR44. On the other hand, the PR44 battery is generally referred to as “Blue Tab” and is mainly used in hearing aids. This battery has a lower beginning voltage (often labeled as 1.45 volts) and a relatively steady output voltage during discharge. PR44 batteries have the largest capacity of all chemistries in the 600-700 mAh range, nearly three to four times greater than silver-oxide batteries.
