Diehard Battery(69)

To choose a 19.2V replacement for your tools, focus on fit and compatibility rather than brand.

• Match voltage: Stick with 19.2V for the same tool platform.
• Check part numbers: Compare the codes on your old pack (e.g., 130279005, 1323903, 315.115410, 315.11485, 11375, 11376, 315.PP2011, 315.PP2020) to the compatibility list on the product page.
• Choose chemistry: Ni‑Cd/Ni‑MH vs. lithium; use the chemistry your charger supports.
• Pick capacity: Options range from about 3.6Ah to 8.0Ah; higher Ah can mean longer runtime.
• Consider multi‑packs: A two‑pack helps with rotation on bigger jobs.

When in doubt, cross‑check tool and charger model numbers before buying.

Charger compatibility typically depends on battery chemistry and model family.

• Identify your charger: Note its model code (many listings reference families like PP2011 or PP2020).
• Match chemistry: Lithium packs generally require a lithium‑compatible charger; Ni‑Cd/Ni‑MH packs use chargers designed for those chemistries.
• Cross‑check part numbers: Ensure the battery lists your tool/battery codes (e.g., 130279005, 1323903, 315.115410, 11375).
• Safety first: Using an incompatible charger can shorten life or cause damage. If you have mixed chemistries, keep chargers and packs paired accordingly.
• Charging tips: Let packs cool before charging and avoid extreme temperatures for best results.

If you’re unsure, choose a replacement that explicitly lists your charger family.

Each chemistry has trade‑offs; the best choice depends on your tools and charger.

• Lithium‑ion: Typically lighter with lower self‑discharge, and often includes protection circuitry. Requires a compatible charger.
• Ni‑MH: A practical option for older setups; higher self‑discharge than lithium. Use a charger designed for Ni‑MH.
• Ni‑Cd: Durable in demanding conditions, but may be heavier and can experience memory effects. Requires a chemistry‑matched charger.
• Compatibility check: Verify your tool and charger model numbers against the product’s compatibility list (e.g., 130279005, 1323903, 315.115410, 11375).

Selecting a chemistry that aligns with your existing charger usually offers the smoothest experience.

“7.0Ah” (amp‑hours) indicates the battery’s capacity—essentially how much charge it can store.

• Runtime: On the same 19.2V platform, higher Ah generally provides longer run times, though actual results vary by tool and task.
• Weight/size: Higher‑capacity packs can be larger or heavier.
• Charge time: Bigger capacities may take longer to recharge, depending on the charger.
• Compatibility: Capacity doesn’t change the platform voltage; still confirm your tool/charger model numbers match the listing.

Balancing capacity with weight and charging time can help you pick a pack that fits your workflow.

Many portable jump‑start/power units use a replaceable sealed lead‑acid battery.

• Match specs: Look for a 12V AGM battery with a similar capacity (often around 18Ah), case size, and terminal type.
• Confirm fit: Check your unit’s model and compare dimensions and terminal orientation to the replacement.
• Install carefully: Disconnect power, note polarity, and secure connections. If you’re unsure, consult the user manual or a qualified technician.
• Recycle: Dispose of the old lead‑acid battery at an approved recycling drop‑off.
