Best Battery Replacement Schedule for a Smart Home: 5 Picks to Keep Devices Alive

A smart home only stays smart while its batteries hold a charge, and the right replacement schedule depends on which devices are in the house. This guide covers five batteries that keep hubs, security panels, sensors and cameras running, matched to three buyer types: the Vivint owner facing a dead hub, the ADT panel owner planning ahead, and the tinkerer stocking a drawer for cameras and sensors. The overview table below shows each pick at a glance before the detailed reviews.

1. Replacement Battery for Vivint Smart Hub Control Panel, VS-SH2000-C00, 12047088-00, 10-600013-001 (5100mAh / 19.38Wh)

Type: Replacement hub battery
Capacity: 5100mAh / 19.38Wh
Compatible Model: VS-SH2000-C00
Part Numbers: 12047088-00, 10-600013-001
Intended Use: Vivint Smart Hub control panel

This is a direct replacement pack for the Vivint Smart Hub, built to the same 5100mAh capacity as the original so the panel keeps its usual backup runtime during an outage. The pack is a drop-in part: the hub opens, the old cell comes out, and this one takes its place without wiring changes. It suits homeowners whose hub has started shutting down during power cuts or showing a low-battery warning that no amount of charging fixes. The listed part numbers make cross-checking against the old battery straightforward.

The pick earns its place because it matches the original capacity exactly rather than trimming it to save cost. Buyers who want the hub to behave as it did on day one should start here. The caution is compatibility: this fits the VS-SH2000-C00 hub and similar part numbers, and a different Vivint panel generation may take a different pack entirely.

Trade-off: The price sits at the higher end for a single replacement cell, so it only makes sense for households actually running a Vivint hub.

2. Energizer 123 Lithium Batteries (6 Pack), 3V Photo Batteries for Smart Home Devices, Cameras and Flashlights

Type: 123 lithium batteries
Voltage: 3V
Pack Size: 6
Chemistry: Lithium
Shelf Life: Long shelf life
Intended Use: Cameras, flashlights and smart home devices

These are 123-size lithium cells, the format many wireless cameras, doorbells and flashlights run on. Lithium chemistry holds a charge on the shelf far longer than alkaline, which makes a six-pack a sensible thing to keep on hand for scheduled swaps rather than a last-minute purchase. The pack suits anyone building a rotation: label the install date on each camera, then replace on a fixed interval. Six cells cover several devices or leave spares for the next cycle.

The pick earns its place on availability and shelf life — a battery that dies on the shelf is useless in a replacement schedule. The caution is that 123 is a specific format: devices that take AA, AAA or coin cells will not fit these, so check the compartment before ordering.

Trade-off: A six-pack of branded lithium cells costs more per unit than generic alkalines, and devices that drain slowly may not justify the premium.

3. Replacement Battery for Vivint Smart Hub Control Panel, VS-SH2000-C00, Fits PN. 12047088-00, 10-600013-001, 5100mAh

Type: Replacement hub battery
Capacity: 5100mAh
Compatible Model: VS-SH2000-C00
Part Numbers: 12047088-00, 10-600013-001
Intended Use: Vivint Smart Hub control panel

This is the second Vivint hub pack in the roundup, matching the same 5100mAh capacity and the same part numbers as the first pick. It is the value option of the pair, aimed at the same buyer: a Vivint owner whose hub no longer holds backup power. Installation follows the same drop-in pattern, and the pack slots into the hub housing without adapters. Buyers comparing the two Vivint options will find the specifications nearly identical.

The pick earns its place as the budget route to the same repair, and the shared part numbers make verification simple. The caution mirrors the first pick: it is built for the VS-SH2000-C00 hub, and owners of other Vivint panel generations need to confirm fit before ordering.

Trade-off: Saving a little on the pack means less margin for error if the listing’s part numbers do not match the old cell exactly — verify before buying.

4. 2800mAh ER14505 Batteries, 3.6V AA Non-Rechargeable 2PCS for PLC, Security System and Smart Oil Fuel Gauge Devices

Type: ER14505 AA lithium battery
Capacity: 2800mAh
Voltage: 3.6V
Rechargeable: Non-rechargeable
Pack Size: 2
Intended Use: PLC, security systems, smart oil fuel gauge devices

These ER14505 cells are 3.6V AA lithium batteries built for industrial and security gear rather than consumer gadgets. The 2800mAh capacity and non-rechargeable chemistry suit low-drain devices that sit unattended for long stretches — PLC controllers, security system components and smart fuel gauge sensors. The two-pack covers a primary device plus a spare, which fits a replacement schedule where the swap happens once and the spare waits in a drawer.

The pick earns its place for anyone whose smart home includes hardwired-adjacent gear that takes lithium AA cells instead of standard alkalines. The caution is voltage: 3.6V is not the same as a 1.5V AA, and putting these in a device designed for alkalines can damage it. Confirm the device’s spec sheet first.

Trade-off: The narrow device list means most households will not have a use for these, and the two-pack leaves little room for stocking up.

5. Replacement Battery for ADT Command Smart Security Panel, 3.6V, Compatible with ADT5AIO and ADT7AIO Models

Type: Replacement security panel battery
Voltage: 3.6V
Compatible Models: ADT5AIO-1, ADT5AIO-2, ADT5AIO-3, ADT7AIO-1, 2X16 AIO, ADT2X16AIO-1, ADT2X16AIO-2
Part Number: 300-10186
Intended Use: ADT Command smart security panel

This is a 3.6V replacement cell for the ADT Command smart security panel, and the compatibility list is unusually broad — it covers the ADT5AIO and ADT7AIO families plus the 2X16 AIO models. The pack is designed for easy installation, so the panel’s backup battery can be swapped without a service call. It suits ADT homeowners planning a scheduled replacement before the panel starts chirping about a low battery. The 300-10186 part number gives buyers a direct cross-reference.

The pick earns its place on fit coverage: one part covers several ADT panel generations, which reduces the guesswork. The caution is that "easy to install" assumes the buyer is comfortable opening the panel housing — anyone unsure should confirm the procedure for their model first.

Trade-off: It only serves ADT Command panels, so it is dead weight for households on any other security platform.

Before You Buy

• Compatibility: Match the part number on the old battery to the listing before ordering — hub and panel packs are model-specific.
• Chemistry: Lithium cells hold shelf life better than alkaline, but 3.6V lithium AAs are not interchangeable with 1.5V alkalines.
• Format: Confirm the compartment size — 123, AA and coin cells are not swappable, and a wrong-format pack is wasted money.
• Schedule: Replace backup packs on a fixed yearly interval rather than waiting for a low-battery warning.
• Storage: Keep spares in a cool, dry drawer and note the purchase date so the shelf life is not wasted.
• Included accessories: These are battery-only listings; tools for opening a panel or hub housing are not included.

Frequently Asked Questions

1. How often should smart home batteries be replaced?
   Backup packs in hubs and panels typically warrant an annual check, while camera batteries follow the device’s own warning. A fixed calendar reminder beats waiting for a failure.

2. Can a 3.6V lithium AA replace a standard AA?
   No. Standard AAs are 1.5V, and a 3.6V cell can damage a device built for alkaline voltage. Only use it where the device specifies that chemistry.

3. Are the Vivint hub packs in this list interchangeable?
   Both match the VS-SH2000-C00 model and the same part numbers, so either fits that hub. Other Vivint panel generations may take a different pack.

4. Do these batteries come with installation tools?
   The listings are battery-only. A screwdriver or panel key may be needed depending on the device housing.

5. Is it safe to store spare lithium batteries?
   Yes, in a cool, dry place away from metal objects. Lithium chemistry holds charge on the shelf far longer than alkaline.

Bottom Line

For most households, the priority is the device that fails loudest: the hub or panel. The Replacement Battery for Vivint Smart Hub Control Panel (B0DTJQLGYD) is the top pick because it matches the original 5100mAh capacity exactly, and the Energizer 123 six-pack is the sensible companion for cameras and sensors. Build the schedule around those two, and the rest of the list covers the specialist cases.
