Batteries & Accessories

Batteries and chargers for cordless power tools, plus storage bags for site work. Sealey's SV-series batteries cover 10.8V, 12V, 18V, and 20V platforms, with capacity options from 1.5Ah to 6Ah. Fast chargers cut downtime, and multi-packs suit crews running multiple tools. Pick capacity to match run-time needs — higher Ah for heavy drain tools like grinders and saws, smaller cells where weight matters more than endurance.

Most cordless systems lock you into one voltage platform — Sealey's 12V batteries won't fit 18V tools, and 20V won't fit 10.8V. Check your tool's model code before ordering. Ampere-hour (Ah) rating sets run-time: a 2Ah battery runs roughly half as long as a 4Ah before needing a recharge, but weighs less overhead. For drills and impact drivers, 1.5–2Ah covers most jobs. Angle grinders, reciprocating saws, and circular saws drain faster — 4Ah or 6Ah keeps you working longer between swaps.

Lithium-ion cells lose capacity over charge cycles. If a battery no longer holds enough charge for a full shift, replace it rather than fight partial run-times. Fast chargers push higher current to cut wait time, but standard chargers work fine if you rotate batteries while one charges. Dual chargers suit two-battery setups — one in the tool, one topping up. Canvas tool bags keep batteries, chargers, and accessories together on-site, particularly useful when moving between jobs or vans.
