- Top Pick: KCATDREY 2 Pack LS14500 AA 3.6V Batteries Replacement for SAFT LS 14500, Use for Smart Gauge Device Alarm Sensor, Non-Rechargeable
- Best Value: JOZELNK 4 X LS14500 3.6V Li-SOCl2 Batteries Use for Smart Oil Gauge, Non Rechargeable
- Premium Choice: Meewellvetry (10-Pack) LS 14500 Battery for LS14500 3.6V AA Battery Applied for Special Testing Electronic Equipment, 2600mah (10PCS)
Type “14500” into a search box and you land in two different worlds. One is the rechargeable lithium-ion cell that hobbyists drop into compact flashlights. The other, and the one covered here, is the non-rechargeable 3.6 volt lithium thionyl chloride cell in the same AA footprint, sold as LS14500 or ER14505 and used in oil tank gauges, utility meters, alarm sensors and industrial controllers. The two are not interchangeable, and mixing them up is the most common way to end up with the wrong cell in your hand.
This guide is for people replacing the battery inside a smart oil gauge, a security sensor, a PLC memory backup or a wireless meter, where the device label says LS14500, ER14505 or a similar part code. Going into 2026, the listings are crowded with pack sizes from two cells to twenty, so the comparison below focuses on what each title states: voltage, capacity where given, chemistry, pack count and the part numbers the cell claims to replace.

How to Choose
Check the part code on your device, not just the size
A 14500 is AA-sized, but a 3.6 volt lithium thionyl chloride cell is not a drop-in for a 1.5 volt alkaline AA, and a 3.7 volt rechargeable lithium-ion 14500 is not a drop-in for either. Look inside the battery compartment or the manual for LS14500, ER14505, TL-5903, SL-360 or SB-AA11. Several listings here name those cross-references, which makes matching easier. Solar-light AA rechargeables labeled 3.2 volts belong to yet another category and do not fit this job.
Compare the capacity figures that are actually printed
Only some titles state capacity. The EEMB ER14505 listings say 2700mAh, while the Meewellvetry and the second KCATDREY pack say 2600mAh. That small gap matters less than the application: a gauge that wakes briefly to report a level sips current, so either figure is a long-lived supply on paper. The JOZELNK, My Battery Supplier and first KCATDREY titles give no number, so treat them as unknown rather than equal. Also ignore the temptation to chase the biggest number: a device that draws power in short bursts will accept either printed figure, and the right cell is the one that matches the connector, voltage and part code your equipment expects.
Match the pack count to your service schedule
Two or four cells suit a single oil tank or alarm panel and a spare. Ten or twenty cells make sense for a technician, a property manager or anyone servicing a fleet of meters. These cells are marketed for long, slow discharge, so buying a bulk lot only helps if you will really use it within a few years.
Know what budget listings leave out
Third-party replacement packs often skip manufacturer details, date codes and connector information. Some devices use cells with solder tabs or a connector rather than a plain AA body, and a bare cylinder will not plug in. If your device uses a leaded connector, read the title for the word “kit” or “connector,” and consider a listing that explicitly mentions your device type before ordering.
The 8 Best Options
KCATDREY LS14500 2-Pack
This pair is a modest purchase for someone who needs to replace the battery in a smart gauge, an alarm sensor or a similar device. The title states 3.6V, AA size, non-rechargeable and positions it as a replacement for SAFT LS 14500.
- Strength: clear non-rechargeable labeling and 3.6V voltage
- Strength: names the SAFT LS 14500 it replaces, easing cross-checks
- Trade-off: no capacity figure in the title
Skip it if you service several devices or want a documented capacity number to compare against other packs. It is best understood as a low-commitment way to get a fresh pair for a single device and keep one cell aside for the next swap.
JOZELNK LS14500 4-Pack
Four lithium thionyl chloride cells aimed at smart oil gauges. The title names the Li-SOCl2 chemistry directly, which is useful because that detail separates these cells from rechargeable lithium-ion 14500s that share the same size.
- Strength: explicit Li-SOCl2 chemistry and 3.6V voltage
- Strength: four cells give you a spare set
- Trade-off: capacity is not listed
Skip it if your device needs a connector-style battery rather than a plain AA body. Owners who just want to confirm the chemistry before ordering will find the title more informative than most, though it leaves out the capacity that some competing packs print.
Meewellvetry LS14500 10-Pack
A ten-cell lot with a stated 2600mAh capacity, aimed at special electronic equipment. It suits a workshop or an installer with several devices on the same chemistry and a regular replacement schedule.
- Strength: 2600mAh capacity is printed in the title
- Strength: ten cells cover a small service route
- Trade-off: the wording is vague about specific devices
Skip it if you only need one set; ten cells is more than most homes will use. Because the wording does not name a device, check the old battery label for the part code and size before assuming it fits your equipment.
EEMB ER14505 4-Pack
This four-pack lists 2700mAh and names a cluster of equivalents: LS14500, TL-5903, SL-360 and SB-AA11. It also mentions PLC, fuel gauge and security system applications, so it speaks to both home and industrial buyers.
- Strength: 2700mAh figure and multiple cross-reference part numbers
- Strength: application list covers PLCs and security systems
- Trade-off: four cells may be more than a single device needs
Skip it if your equipment calls for a battery with wires or a plug attached. The extra detail in the title is what sets this listing apart: a reader can match a part code from a manual to one of the named equivalents without guessing.
My Battery Supplier Replacement Kit
Sold as a replacement kit for a smart oil gauge built around the SAFT LS14500, this listing is tuned to a narrow audience. The title confirms 3.6V, Li-SOCl2 chemistry and non-rechargeable operation.
- Strength: written around one specific gauge use case
- Strength: states chemistry and voltage clearly
- Trade-off: the title does not give a pack count or capacity
Skip it if you need to confirm how many cells arrive before ordering. The narrow focus is a plus when the gauge matches and a drawback if your device is something else, such as a meter or a controller.
KCATDREY LS14500 4-Pack
The four-cell KCATDREY lists 2600mAh and a smart oil gauge as its intended use. It is a straightforward restock for an oil tank monitor owner who wants a spare set after the first swap.
- Strength: capacity is stated at 2600mAh
- Strength: four cells cover a full change plus spares
- Trade-off: title is short on compatibility details beyond the gauge
Skip it if your device lists a different part code such as TL-5903 and you want it spelled out. For the same chemistry with a longer list of equivalents, the EEMB listings are more explicit.
EEMB ER14505 10-Pack
This ten-cell box repeats the 2700mAh figure and Li-SOCl2 chemistry, with water and gas meters, PLC systems and alarms in its use list. It is a good fit for a maintenance tech who services different device types.
- Strength: 2700mAh and Li-SOCl2 stated together
- Strength: use list spans meters, PLCs and alarms
- Trade-off: ten cells is a lot for a single homeowner
Skip it if you need a quick one-time swap on a single oil gauge. A technician who services mixed equipment will get more from the box, since the title speaks to meters, PLC systems and alarms alike.
EEMB ER14505 20-Pack
The largest lot in the group: twenty cells at 2700mAh with the same cross-reference names as the four-pack. It is meant for facilities that keep sensors and smart meters running on a rotation.
- Strength: highest cell count and 2700mAh printed capacity
- Strength: lists LS14500, TL-5903, SL-360 and SB-AA11 equivalents
- Trade-off: far too many for an occasional user
Skip it if you cannot store and use twenty cells before they age. It makes the most sense when one person controls the stock and records the date each cell goes into service, so no device runs on an old swap.
Which One Fits Your Situation
Replacing the cell in a home oil tank gauge
The My Battery Supplier kit or the KCATDREY 4-Pack matches the home gauge scenario, with the SAFT LS14500 wording or a smart oil gauge named in the title. Pick the kit if your gauge model is SAFT-based, and open the old battery cover first to confirm whether the cell is a plain cylinder or comes with a connector.
Maintaining PLCs, alarms or industrial controls
The EEMB ER14505 4-Pack stands out because it states 2700mAh and lists several equivalent part codes, so you can match it to a controller manual.
Servicing a route of meters or sensors
The EEMB 10-Pack or 20-Pack fits installers and facility teams, while the Meewellvetry 10-Pack is a smaller bulk option for a lighter service round. Label each bag with the swap date and keep unopened cells in a cool, dry cabinet away from metal objects.
Needing only a quick swap
The KCATDREY 2-Pack or the JOZELNK 4-Pack keeps the order small, which helps if you do not want to hold stock. Either way, write the install date on the device cover so the next change is easy to schedule.
Common Mistakes
- Buying a rechargeable lithium-ion 14500 for a device that expects a 3.6V lithium thionyl chloride cell
- Putting a 3.6V cell into a 1.5V AA holder and risking damage to the electronics
- Ignoring the part code (LS14500, ER14505, TL-5903) printed on the old battery
- Overlooking connectors, since many gauges use a wired battery rather than a plain AA body
- Buying a bulk lot and leaving it unlabeled for years, so nobody knows which cells are fresh

Frequently Asked Questions
Is LS14500 the same as ER14505?
They are closely related names for a 3.6V lithium thionyl chloride AA-sized cell. The EEMB titles list LS14500 as an equivalent to ER14505, but always confirm against your device manual.
Can I recharge these cells?
No. Every listing here is non-rechargeable. Trying to charge a primary lithium cell is unsafe, so keep them away from chargers made for lithium-ion 14500 cells.
Why are some capacities listed and others not?
Sellers choose what to put in the title. Where capacity is missing, treat the capacity as unspecified rather than assuming it matches a 2600mAh or 2700mAh listing.
How many cells should I order?
Count the cells in each device and add a spare set. Reserve ten- and twenty-cell lots for maintenance teams that rotate through many devices.
