How we scored them

The Solar Score weighs performance, build, value, safety and warranty. For a battery hold down, safety means a secure, corrosion-resistant hold the listing actually states; all five featured listings name one. Only one featured listing states a warranty term, the Dorman with its Limited Lifetime Warranty. No featured listing states a certification mark.

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 battery hold down

Pick the style that matches your battery

Three styles appear here. A base clamp like the Dorman 00588 bolts at the battery’s base and replaces the original equipment piece; it fits select Ford, Lincoln and Mercury models, so check the application list before ordering. Adjustable crossbars from ARONOVA, Aoerzn and LYCARESUN span the battery’s top and fit a wide range of group sizes, which suits RVs and boats where the battery group may change. The billet bracket from ARONOVA is a machined 6061 aluminum crossbar with J-bolts for flat-top batteries. For the battery side of the setup, see our Deep Cycle and RV Batteries guides.

Match the width and the bolt length

Fit is the first measurement. The ARONOVA 10 in kit adjusts from 5.35 to 7.85 in wide and offers J bolts in 8, 9, 10, 11 and 12 inch lengths; the Aoerzn adjusts from 5.32 to 7.86 in with 10 inch J bolts. The LYCARESUN crossbar adjusts from 13.5 to 20cm with 27cm or 24cm L-bolts. The ARONOVA billet bracket is 8.58 in long with a 7.48 in bolt center distance and fits batteries up to 6.89 in wide, but the listing warns it will not fit between raised vent caps on some batteries. Measure the battery and the tray before choosing a length.

Read the materials for corrosion

Underhood metal lives a hard life. The ARONOVA 10 in kit pairs a premium iron crossbar with 304 stainless steel J bolts and fasteners under a baked-on powder coat finish. The Aoerzn uses iron and stainless steel with a sprayed finish for corrosion and rust resistance, and the LYCARESUN uses premium iron and stainless steel with an anodized matte finish. The ARONOVA billet bracket is CNC-machined 6061 aluminum with full 304 stainless steel hardware and a dual sandblasted plus anodized finish; its listing contrasts this with galvanized iron alternatives that rust under engine heat and vibration. None of the featured listings states a certification mark, so material claims are what you compare.

More options in this range

Five more listings cover nearby needs. The ARONOVA 8 in J hook kit is the same adjustable crossbar as the featured 10 in kit, 5.35 to 7.85 in wide, with 8 in bolts and an item weight of 8.4 ounces. The BFXM black aluminum tie down is an 8.5 in bracket with 10 in J-bolts: its bullets give the bracket as 8.54 by 1.76 by 0.27 in with a 7.48 in bolt spacing and a 4 in screw section, while its spec table says 5 by 2 by 0.5 in, so trust the bullets. The BFXM blue listing describes the same kit but states an item weight of 2.4 ounces against the black listing’s 6.4 ounces, so its weight is unclear. The ecocstm base clamp is a PP clamp with 304 stainless bolts, a 2.87 by 1.36 by 1.07 in bracket and 2.09 in bolts, fitting select Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac and Saturn models with OEM number 14005061. The EXVITAL kit is a different style entirely: two 1 by 48 in nylon straps with zinc alloy cam buckles, 4 stainless steel brackets and 8 stainless screws, listed for boat and RV use at 0.25 kg.

Sizing Notes

  • Measure the battery’s width and the tray before ordering; adjustable crossbars here span 5.32 to 7.86 in, and the L-bolt kit spans 13.5 to 20cm.
  • Pick the bolt length for your tray depth: 8 to 12 in J bolts on the ARONOVA kit, 27cm or 24cm L-bolts on the LYCARESUN.
  • Check the application list on OE-fit clamps: the Dorman fits select Ford, Lincoln and Mercury models, the ecocstm fits select GM models.
  • Note vent caps: the ARONOVA billet bracket does not fit between raised vent caps on some batteries.
  • Compare materials where no certification is stated: 304 stainless hardware and anodized or powder coat finishes resist underhood corrosion.
  • Keep the straps as an option for boats and RVs where a crossbar does not suit the tray.

Frequently Asked Questions

What is a battery hold down?

It is the bracket or clamp that bolts the battery to its tray so it cannot shift on rough roads or during hard braking. The listings here show three styles: base clamps, adjustable crossbars and a strap kit.

What is a battery hold down type?

The common types are base clamps that bolt at the battery’s base, like the Dorman 00588 and the ecocstm; adjustable crossbars that span the battery’s top with J-bolts or L-bolts, like the ARONOVA, Aoerzn and LYCARESUN; and strap kits like the EXVITAL with cam buckles.

How does a battery hold down help battery life?

The Dorman listing states that reducing battery movement helps ensure maximum battery life, since a shifting battery wears cables and terminals.

Will these fit my battery?

Check the listing’s fit range against your battery. Adjustable crossbars list width ranges, such as 5.35 to 7.85 in on the ARONOVA kit, and the ARONOVA kit lists compatible group sizes including 24, 24F and 34. OE-fit clamps like the Dorman fit only select models.

Does a longer bolt matter?

It matters for tray depth. The ARONOVA listing offers J bolts in 8, 9, 10, 11 and 12 inch lengths and advises measuring the battery to confirm the bracket fit and the proper bolt length.
