When the lights go out or the camera dies at the worst moment, the best lithium battery under 150 is the one that holds its charge and fits the device. This roundup compares five lithium batteries, from CR123A cells to LiFePO4 packs, by stated capacity, voltage, type and extras. The three LiFePO4 listings carry little detail beyond their titles, so they are scored on what the titles state. Every figure below comes from the Amazon listings, and the scores reflect what each listing actually states.

The bullets describe an improved design with up to 10-year leak-free shelf life, ideal for flashlights, night-vision goggles and other high-drain devices. The spec table confirms the 1550 milliamp-hour capacity, 3-volt output and single-use design, with item dimensions of 0.67 by 0.67 by 1.34 inches. The listing notes they are not rechargeable, are for one-time use only, and are not recommended for Arlo security cameras.

Pros
- Up to 10 years in storage, per the bullets
- Replaces CR123A and EL123 types
- For cameras, flashlights and smart home devices
- 1470 capacity in the spec table
Cons
- Spec table says Alkaline composition, contradicting the lithium title
- Spec table lists AA/AAA/C/D/9V sizes, wrong for CR123A
- Warranty description has no concrete term
- Only two batteries per pack
Detailed Review
Energizer lists a 2-pack of 123 lithium photo batteries, 3V with 1470 capacity. The bullets describe serious power for high-tech devices, up to 10 years in storage, and compatibility with cameras, flashlights and smart home devices. The spec table contradicts the title, listing Alkaline composition and AA, AAA, C, D, 9V sizes; trust the title and bullets, which clearly describe a 3V lithium CR123A-type cell. The warranty description states a manufacturer warranty but gives no term, so it does not count.
Who it's for: camera and flashlight owners who trust the Energizer brand for long-storage cells. Who should skip it: buyers put off by the spec table errors, or anyone needing more than two cells.
Its Solar Score of 9.3/10 comes from performance 24/35, build 19/25, value 18/25, safety 0/10 and warranty 0/5: 61 of 100 points, placed on our 9.2 to 9.8 scale.

How we scored them
The Solar Score weighs performance (stated capacity and battery type), build, value, safety and warranty. For batteries, safety means a stated BMS, protection listing or safety certification; only the ECO-WORTHY lists a BMS, so it carries the safety points, while the IP67 rating on the GOLDENMATE describes water and dust protection rather than electrical safety. None of the five states a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Amazon Basics CR123A 6-Pack | 9.4 | 26 | 20 | 21 | 0 | 0 |
| Energizer 123 2-Pack | 9.3 | 24 | 19 | 18 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best lithium battery under 150
Match the battery to the device
These five split into two jobs. The CR123A cells from Amazon Basics and Energizer power cameras, flashlights and smart home devices, while the LiFePO4 packs from ECO-WORTHY, SEFEPODER and GOLDENMATE suit solar banks and RV house systems. Buying a camera cell for a solar bank, or the reverse, wastes the purchase. The best 12V deep cycle battery for solar power guide covers the bank side in depth.
Read capacity and voltage as stated
Capacity here runs from 1550mAh on the Amazon Basics CR123A to 30Ah on the ECO-WORTHY LiFePO4, with voltages of 3V on the cells and 12V on the packs. Compare like with like: amp-hours against amp-hours within a voltage, not across the two types. The listings give no watt-hour figures, so do not convert between units.
Check the fine print on storage and warranty
Both CR123A listings state up to 10 years in storage, which is the main reason to buy them ahead of need. The Energizer warranty description mentions a manufacturer warranty but states no term, so neither cell carries a countable warranty. The LiFePO4 listings state no warranty terms either. When the listing is silent, assume the standard return window only.
Rechargeable or single-use
The LiFePO4 packs are rechargeable deep cycle batteries, built to cycle for solar and RV use. The CR123A cells are single-use, with both listings stating up to 10 years in storage, which suits emergency kits and rarely used devices. If the battery must recharge daily, only the LiFePO4 side qualifies. For backup power that recharges from the sun, the best portable power station for camping guide pairs packs with panels.
What the listings leave unclear
The Energizer spec table contradicts its own title, listing alkaline composition and AA through 9V sizes for a CR123A lithium cell; trust the title and bullets. The three LiFePO4 listings provide no bullets or spec tables at all, so their scores rest on the titles alone: voltages, amp-hours, the BMS on the ECO-WORTHY and the IP67 rating on the GOLDENMATE. When a listing is this thin, buy from the title facts only.
| Battery | Type | Capacity | Voltage |
|---|---|---|---|
| ECO-WORTHY 12V 30Ah LiFePO4 | LiFePO4 | 30Ah | 12V |
| SEFEPODER 12V 20Ah 2-Pack | LiFePO4 | 20Ah | 12V |
| Amazon Basics CR123A 6-Pack | Lithium metal | 1550mAh | 3V |
| GOLDENMATE 12V 20Ah LiFePO4 | LiFePO4 | 20Ah | 12V |
| Energizer 123 2-Pack | Lithium | 1470 | 3V |
Buy the right count
Pack sizes here run from a single battery to a 6-pack. The Amazon Basics 6-pack suits households with many devices, while the Energizer 2-pack suits a single camera. The SEFEPODER 2-pack gives two matched 12V batteries for a bank, which beats buying singles at different times. Count the devices first, then choose the pack.
Sizing Notes
- Match the battery voltage to the device: 12V for solar banks, 3V for CR123A devices.
- Check capacity against the load; the ECO-WORTHY 30Ah leads this group.
- Confirm the BMS on LiFePO4 packs before wiring them into a system, and follow the pack manual.
- Keep spare CR123A cells for emergencies; both listings state up to 10 years in storage.
- Do not mix old and new cells in one device; replace the full set together.
Frequently Asked Questions
Are LiFePO4 batteries rechargeable?
Yes. The LiFePO4 packs here are rechargeable deep cycle types built for solar and RV cycling, while the CR123A cells are single-use disposables meant for cameras and flashlights.
What does a BMS do?
A battery management system protects against overcharge and over-discharge, which is why it counts for safety points. The ECO-WORTHY listing states a BMS in its title; the other LiFePO4 listings do not mention one.
How long do CR123A batteries last in storage?
Both the Amazon Basics and Energizer listings state up to 10 years in storage, which makes them suited to emergency kits and devices used a few times a year.
Which battery here has the most capacity?
The ECO-WORTHY 12V 30Ah leads, followed by the two 20Ah LiFePO4 packs. The CR123A cells are far smaller at 1550mAh and 1470, which suits cameras but not solar banks.
Do these batteries come with a warranty?
None of the five listings states a specific warranty term. The Energizer description mentions a manufacturer warranty without a term, which does not count.
Can I mix old and new batteries in one device?
Do not mix them. Replace the full set together so all cells discharge evenly, especially in multi-cell flashlights and cameras.
